  1. I can't speak for the Koni engineers (and I'm certainly not one, lol), but as best as we understand it: The strut insulator does not impact on the Koni sleeve either way it is installed. The insulator impacts on the strut bearing in the front (or the strut spacer in the rear), and they in turn impact on the top of the spring seat. The Koni sleeve sits slightly under the top of the bearing or spacer (otherwise it would grind when you make a turn), and is not impacted. The bump stops were originally bonded to the underside of the spring seat. If you bottom out, the bump stop takes the impact between the strut body (Gland nut) and the upper spring seat, the Koni sleeve is in-between and isn't impacted either way. As far as damage to the bump stop, that is an engineer question for sure, but it *seems* like the only time there is pressure on the bump stop is when it bottoms out, and then all the stress is between the top of the bump stop and the spring seat, and the bottom of the bump stop and the Gland nut. I'll try to get this discussion seen by those engineers to get their corrections/thoughts.
  2. You are exactly right, sorry about that, I had forgotten all about posting that previously. I blame 2020, lol... Koni made this setup with the sleeve because that is the way they did it back in the early days. So for these struts, they copied that same setup. Koni told us that originally it was done that way as some coil over kits would not work with the diameter of the shaft, and they therefore chose the sleeve design so it could be optional if necessary for custom setups/coil overs/etc. (Koni always tries to think of racers as well as enthusiasts whenever possible). When the image on the left was posted, we had queried Koni and they agreed that was a proper way to set it up, and will work fine that way. When our drafting-talented customer made the image on the right, we queried Koni again about it. They had the engineers (i.e. smart guys) go through it all again, and their final determination was that once the weight of the car is down on the setup, it matters not which direction the sleeve is placed, as it ends up functioning exactly the same while in actual use. So if you install/installed them with the "flange/ledge" at the bottom, all is well. If you install/installed them with the flange/ledge at the top, all is well. The smartest guys in the room determined that it makes no difference. I'm sure people will add their own thoughts, which is part of what forums are great for. In our own non-engineering minds, having it with the ledge at the bottom might hold the bump stop (at least our urethane bump stops, which we recommend with these struts) in a bit more favorable position. At the same time, having the ledge at the top might work better with different bump stops, and to be extremely non-technical, "looks" better and more natural to us, and might make initial installing slightly easier due to the pre-compression height of the parts while installing (possibly useful if you have stubby fingers like I have). But literally, direct from the Koni engineers, when it comes to how the strut assembly functions, the "ledge/flange" part of the sleeve is irrelevant as to position. Both are Koni engineer approved.
  3. John, let us know when you're back, and we'll go from there for Gland Nut measurements, and/or getting them back here. As far as the ones you used, as long as the ID of the inner opening that seats down on the strut matches extremely close to the top of the KONI, we would assume you'd be ok, but there may be factors we're not thinking of. If there is any movement at all, the damage could grow over time. We'll figure it out.
  4. Sorry you’ve had trouble. One manufacturer’s Strut Cartridges should not be used with another manufacturer’s Gland Nuts, so let’s see what we can figure out. Which Gland Nut you used there doesn’t necessarily matter to what we’re trying to figure out here, but to cover all the bases, the one shown in your video is not an original Nissan 280Z Gland Nut. The original nuts had seals to keep the oil fill inside the shaft where the plunger rod was, and it would not fit down properly on top of the strut cartridge body (I was curious to see if we had an original Gland Nut here, and found one, so included images in case others wanted to see them). When manufacturers started making physical strut cartridges to replace the original non-cartridge setup, they all included their own specific Gland Nuts, as they needed to match the shape of the top of the strut body. Just like with Koni, that Gland Nut is the exact inverse of the top of the strut body. Depending on what strut cartridge manufacturer made that Gland Nut, it may or may not be fitting well on top of the Koni strut body; which, if not, could allow strut cartridge movement and damage. The only way that a Gland Nut could slip when tightening would be if they somehow were incorrect nuts (difficult to imagine, but not completely impossible that some random Koni application has Gland Nuts that are nearly identical but just slightly smaller, and were mistakenly put in the box), or if the threads are damaged on one side or the other (which you said the threads weren’t), or there is damage to one part or the other (even stress/wear/cracks/stretching/damage to the strut housing tube itself). Also, in your video the top of the housing seems to be shiny clean as if machined somehow. It may not be relevant, but do you know what was done to the top of the housing tube there? As far as the Gland Nuts you received, if you are able to measure them for us, knowing the exact dimensions and thread pitch/details would help us try to figure it out. Otherwise we could also just get those back here from you and confirm if they are correct. Since the Koni Gland Nut is the exact proper fit for the Koni Strut, then we should see what can be solved so that you can use Gland Nuts that hold the Strut Cartridge in the proper position. Let us know. (the first two images are of an original Nissan Gland Nut (with seal), and the third is the underside of the Koni Gland Nut shaped to fit the top of the Koni cartridge exactly)
  5. That is the one from Thailand I was referring to in my email discussion with you. Unfortunately he doesn't sell wholesale or bulk. We hope to have some additional options (much less expensive than the actual reproduction version we currently sell) available soon.
  6. No product failure is ever welcomed, and we will certainly be talking to the manufacturer about this one, and continue to monitor them. We're of course very sorry that both of your products had obvious issues. We have sold over 180 of them since 2016, and these are the first two alerts we know of concerning this issue (possibly 3 assuming the one from Hybrid was the same manufacturer, which is hard to tell for sure, since there have been a few similar options on Ebay over the past couple of years, some of which are no longer around). Hopefully it is not more than 2-3 out of 180 and not indicative of a mass or new problem, we'll certainly look carefully at the next batch we receive. As far as we know the rest of the 180 that were installed are working fine to this day. If other members have had the same issue with this style, please let us know. Certainly Greg and this company have not stayed in business for over 40 years by ignoring reports like this, they are all taken seriously, and again, we'll make sure the manufacturer is aware of it. We do apologize, Madkaw, for the delays. Being severely short-handed for over a year now, Greg himself is having to take care of all the returns, along with a number of other missing staff positions, and we have been quite overwhelmed and behind. Sorry that it took extra time to get everything processed. We're working as hard as we can, and working hard to find more team members at the same time. We of course responded personally to zKars, and are processing his refund now. As a side note, unfortunately James has been on a leave of absence since mid last year, so if you have, or do, try to message him, unfortunately he won't see it. We're also hopeful that James might be able to return at some point.
  7. Thanks Zed, always appreciate you looping us in. Lee already knew, as Koni has been conversing with this customer directly this week. Lee himself will be in soon with a direct response. James is on a leave of absence, which is why there haven't been any responses from him for a while. Thanks again!
  8. Lee from KONI has been made aware of these things. He is getting caught up (I'll never complain about my flooded inbox again, since he said his had around a thousand messages, sheesh!) and will be coming in soon for the following: 1. He has a simple something-or-other for those who for some reason need a longer adjuster knob. As far as we know, for the many hundreds that have sold so far, only two Z-Cars have had the issue of not being able to reach with the knob for some reason. We honestly don't know why at this time, but hope to research it and find out. Lee was gathering the information he had on his fix, and will share that soon. If anybody else has this issue, please let us know at (800)633-6331 or info@motorsportauto.com. 2. Lee and his engineers are looking at Madkaw's situation. Since that is miles above my pay grade, I'll leave that to Lee and his engineers, and look forward to what they have to say. He may have some other things to address, but those are the highlights. As far as what you said Madkaw, yes, we sent them O.E. 240Z, 280Z, and 280ZX strut housings, just to confirm everything. They already had the proper sizing from all the years they did the Reds, and this was just to confirm, which they did. As far as grinding the inside of the strut tubes, that was a misunderstanding on us. We should have been more clear that we've heard of many struts (and have some here in the building) where there is a hardened gunk buildup at the bottom from years of oil and such. That is often needed to be cleaned out, often by "grinding" with something to break off the gunk. However, grinding of the metal at the bottom of the inside is not something anybody should do and not what we intended to convey. Again, our apologies that we "muddied" that up, pun intended. Thank you for your patience on this Madkaw.
  9. Man, Koni has a lot of events! Lee had to go back on the road to another one before he could finish catching up on all requests and so forth. I believe he gets back mid next week, but I gave the impression here that he was back and soon to be jumping in, which was inaccurate. My fault, sorry for the confusion.
  10. Definitely not 4mm in my image. Just made that to be clear and confirm to everybody what the measurement was supposed to be measured from and to. I think Lee may be back but I'm sure is trying to unbury himself. I hope to get some confirmation before the end of the day (I'll try anyway).
  11. Sorry if whom you spoke to sounded as you describe. We're all a bit hair-on-fire trying to keep up with short staff, but that isn't an excuse. 1. Please private message me about who you spoke to here. 2. Before I (and/or Lee) respond to the rest, I need to confirm that the image you included is torqued down; and using the diagram I included below, you're saying on that strut the same gap is 6mm? It is hard (for me anyway) to tell from your image. 3. Well over 90% of the 240Z's, including many 70-71's, have been within the 4mm gap tolerance with the original gland nut. So far, of the very few single digit numbers of anomalies we've heard of, the modified KONI gland nut has brought the gap back into their prescribed tolerance of 4mm just fine. Yours would be the first to not be solved. 4. Please do not grind anything until I (and/or Lee) get back to you. Thank you for your patience.
  12. Sorry folks, you may have seen the note we put up in our store, this Covid thing has forced a couple more guys to step down to take care of family, including James temporarily, and we were already short on warm bodies, so we've been a bit overwhelmed, but still standing and swinging. We have a couple of new guys starting soon, both of them Z owners, so if we've missed any of your emails or messages know we're working hard to get caught up. I was able to check in with Lee between his recent business trips. He is traveling (again), and having log-in issues, but I mentioned the Stainless issue to him and he said that the hardware is chromed steel, not stainless. Now that discussion is above my pay grade, lol, so I'll let Lee pick up any further questions when he gets back. It has already been answered previously, but that disc is completely there just to avoid possible air damage to the seal, by giving paths for the air to move freely if the bump stop comes all the way down. I guess they used to see it happen way back and thus came up with the disc as a simple yet fully effective solution. One of the projects that has suffered with the current situations is making a picture-gram of how the pieces go together on the strut just to add clarity. The sleeve and the bump stop go together like this image I took. I believe this was also described early on in this thread, but I never made it to making that diagram/image. Sorry about that. I'll make a real one soon with all the pieces. Then instructions are also something Lee is looking into, but those wheels turn pretty slow, especially with our current world. Somebody said it was done like that to make it work for all languages, which is exactly correct. We hate to see that anybody had any trouble with their struts, but it is great to hear from so many who love the performance. Ok, it's nearing 10:30 pm here in SoCal, back to answering more emails!
  13. Hopefully that takes care of it, just make sure that when you torque them down, there is a 4mm or smaller gap between the housing top and under the gland nut flange. If anything doesn't seem right, just contact us directly. Thanks!
  14. Hello @fyrst.z, like Zed said, the gland nuts definitely are specific to the struts, and you should use the Koni gland nuts. If you have one side of the front that threads and the other side that doesn't, that definitely could be, also as Zed said, decades of dirt and oil that create a "spacer" down there, so check that as well. The only other options would be non-matching strut cartridge heights, which will be fairly easy to check, or damaged/modified/mismatching strut housings. Struts, whether Tokico, KYB, Koni, are different heights, and they all have different gland nuts to go with them. You show an image of a strut installed with what looks like a KYB gland nut, we assume you are not using those gland nuts on the Koni's. When you're certain there isn't a buildup to scrape out of the bottom of the housing tubes (it isn't easy, unfortunately), and if then using the Koni gland nuts you are not able to torque them down to a 4mm gap, regardless of side, just give our sales technicians a call at (800)633-6331 or (714)639-2620, or email if you prefer at info@motorsportauto.com, and we'll get things figured out.
  15. Sorry for the slow reply. While all brands are always subject to availability, the wheel bearings we've had for a good while now are Koyo (Japan). They have been excellent quality so far. If you have any further questions you can always ask James@thezstore directly for a faster response ?
  16. Jonbill, another helpful confirmation would be to see if you can get the numbers off of the strut housings, and we'll check from that angle. What else was telling you that the build date might be earlier?
  17. Most of you know Hector Cademartori, the renowned Automotive & Racing Artist, and have seen his great work. We have many of his creations available on our website. Some may not know that he makes a Classic Datsun Z Christmas Card every year. With all of the same old winter scenes and Christmas trees repeated over and over most years, these cards are a fresh option if your family sends out Christmas Cards. They also make great collector's items. This is the fourth edition Hector has created (these are prints, the original of course was painted by hand). Here is what the Artist had to say: The Christmas cards are the highlight of my year. I produce five or six every year for different clients, all of them involving cars or motorcycles, and I've been doing them for over 25 years. Since Christmas cards don't have a commercial target (beyond their retail price), I have plenty of freedom to come up with situations involving Santa Claus, his helpers and all the elements of a Christmas scene around cars and motorcycles. It's fun to come up with new ideas and enjoy adding elements in the background pertinent to the subject matter. I get comments from the most observant in the audience about a poster on the wall or a little racecar in a dark corner. For instance, in this year's art I included a toy fire truck. It's my friend Dan Banks', a well known Datsun collector and historian from Maryland who owns the real thing. We included some sequences from rough sketch to final art. Thought they'd be of our customers' interest. This is my fourth Datsun Christmas card and I look forward to next year's design. Merry Christmas and Zeason's Greetings!

  18. Oops... Guess what arrived in September just like we said? Our apologies for saying we'd announce it when they arrive, and then neglecting to... Here they are! The front 280ZX cartridges look and function basically the same as the 70-78. However the rear shock/spring seat version features a little extra. Note that these are designed with a 3 position spring seat perch. So if you know you will be touring often with lots of luggage and want a bit more ride height, you can set them to the top position. If you want them to ride a little lower, set them to the bottom position (they are set during installation, to change the position later, the struts must be removed). Nice little option to have available, thanks Koni! So now the Koni Adjustable Sport Yellow Struts/Shocks have been completed for all of 70-83 240Z, 260Z, 280Z, and now 280ZX. We've heard some good reports so far where people like how they function, especially with Eibach Springs. Thanks again to Koni and Lee Grimes (KONI Lee) for all the great work!

  21. Our apologies to all of the patient 280ZX owners, sorry for the delay, as Koni had to spend some extra time on the more-difficult-to-create rear units to make sure they were right. As far as we can tell, they went into production in mid-July. After that, sea freight generally takes about 6 weeks to arrive to Koni in the U.S., and then from Koni U.S. to our warehouse about another week or so. If all goes according to plan... then hopefully that means we'll have them in stock sometime after mid-September. We hope to have images soon, and of course will announce it here when they arrive.
  22. In case you missed it, 70-78 Koni Sports are in stock! Check the early discussion thread for more details.
