My 7/76 has a space saver Yokohoma in it. But I don't think it's stock. Wheel well looks like it takes a full size tire. FSM has no information on spare tire. Haynes manual has an addendum that says all 280Z's from 1975 have C78-14 space saver tires. S30 Wiki says 1977 and up 280Z's had space saver with sloping rear deck and an enlarged fuel tank. FWIW...

I guess I wasn't clear enough. Yes, a tubeless tire will work on that rim without a tube. Clear enough?? The rim is not manufactured as a Tube or Tubeless type. You just change the valve stem. That's the only difference. Either type of tire can be mounted on them with or without a tube. It is a universal design. You only need tubes in some really old style rims, ( pre-1956 ), or if you have wire wheels with spoke holes in them.

Thanks Jeff... maybe I'll have to keep looking. My Conti Extreme Contact DW tires are very good in the wet. Need something with good wet grip. Wonder what the BF Goodrich rivals are like in the wet

Transister Ignition Unit is not in engine bay. It is the passenger side footwell behind a plastic kick panel just in front of the door. Check all your fuses of course

Not too concerned about not being the " latest and greatest". But the Azenis 615 comes in a size that I like ( 215/45x16) . What I am most concerned about though is wet grip. From reports I have read, it rates fairly high for wet grip. That is quite important to me as we get a lot of Rain in the PNW . What were your impressions of the tire Jeff? I'm not too concerned about competition use. I may run the occasional Autocross, but no Track Days. TIA.

I'm having a good hard look at the Falken Azenis RT615K in a 215/45x16. That's 23.6" in diameter and 7.6" Tread width on a 7" wide rim . The other tire is the Firestone Indy 500 in a 205/45x16. That's 23.2" in diameter, but it's only 6.9" Tread Width on a 7" rim.

Here's the one I bought. Resolution on a PC is 1280 x 720 wich is pretty darned good. Waterproof as well. Works with Android 4.0 OS and above and Windows XP and above. Smart Phone must have OTG function. Don't know if it works with IPhone, because Apple has proprietary software. http://www.ebay.com/itm/5-5-7mm-Digital-USB-For-Android-Borescope-Endoscope-Inspection-Waterproof-Camera-/162214076703?var=&hash=item25c4b6611f

Yeah... not all Android devices work. OS has to be one of the later versions that has Automatic detection for plug in USB Camera's. I have a BB Z10 and it doesn't have the capability, but a Z30 does. With my laptop and WinXP it is detected just fine and runs with Windows Media Player. Laptop has far higher resolution than most smart phones. Warning. Don't load the software drivers included with the endoscope. It is laden with Malware, as are most of those Chinese mini-disc drivers.

My biceps grew an inch in the first year after buying my 280Z. 225/50x16 Conti Extreme DW ties are a very nice tire but HEAVY steering. Autocrosss can be a challenge in a Z with wide sticky tires. You may want to consider electric Power Steering. SilverMine motors has just come out with a new kit that is a complete bolt in. A friend of mine has 275/40 x 17's on the front of his 240Z with EPS. He can crank up the assist with a rheostat so that he can park it with one finger if needed.

Just personal choice. I find the overall diameter of the 225/50 x16 is a bit too large. I prefer a smaller diameter tire on the car as I will be lowering it further and I am going to have an issue with fender rub. Main reason I went with 16" rims is because of tire selection and I have a BBK up front with 12" rotors and Z32 four piston calipers. Tire selection has improved lately in 15's though and it turns out the 15" Rewinds would have cleared the calipers. I've seen 205/50x 15's on a local car that is lower than mine and it is the look I want. It has the same wheels and it just looks more " correct " . The sidewalls are also a bit too flexy, with a 225/50 x16. Makes for a comfortable ride, but corner turn in is a little too slow for my taste. The other issue with the 225/50 x16's is that the steering is really heavy. That is more of a tire design issue though ( Conti Extreme DW ). My biceps grew an inch the first year I drove the car. No kidding!! I've heard that the Firestone Indy 500 tire has very light steering, so I may go with those down the road.

I bought one of those off E-Bay a while ago. I figured for $10, how can I lose. I was pleasantly surprised by the video quality, The one I got could be used with Laptops, Andriod phones/tablets and I-phones/Tablet. They come with little attachable hooks and magnets so you can retrieve those screws & washer that you dropped. Handy little device. Question is. How long before you stuck it down your throat and looked at you teeth, tongue and tonsils? Most guys seem to do that in the first 5 minutes....

Stock rims on 280Z are tubeless. Spare tire rim though, is a space saver tire I believe. At least it is on my 1976. You shouldn't put a regular tire on it. Don't even know if you can, because a space saver is a special size. I'll have to check my spare tire after breakfast... still a bit of " morning Fog "

Done all the time. Just curious. What year and model is the rim off of? Tubeless tires have been standard equipment on new cars since 1955. https://en.wikipedia.org/wiki/Tubeless_tire Edit: Some Rally guys used to run tubes in tubeless tires, because it kept the tire inflated if you hit a rock and damaged the bead area of the rim or tire. I did this on my Rally 510. Off Road drivers do the same thing.

Here's a picture of my 76 280Z on 16 x 7 Rewinds. Gunmetal gray. Tires are Conti Extreme Contact DW in 225/50 x16. Car is currently on Eibachs, but I am having some Coil overs made using a TT3 DIY kit. I'll drop the car another inch or so. Want tires level with top of fender openings. May go with a shorter profile tire when I lower car. 225/45x16's are 24.9" in diameter. A 215/45x16 is 23.6" in diameter. Some good tires in that size. Will be installing 240Z JDM bumpers front and rear. I'm on the fence about the side skirts and rear valance. PO installed those. I prefer the original look like Mike W's car ( Nicely done sir ). But it is a lot of work to remove them due to how they were mounted and a partial or complete re-spray would be needed. What do you guys think? Keep the side skirts and rear valance, or get rid of them?

Juts a further FYI. Official Crane instructions for installation and mounting of all Crane coils. There is no mention that Crane oil filled coils cannot be mounted horizontally: http://www.cranecams.com/uploads/instructions/9000-1091_.pdf

PS20 is still a fine coil, regardless. Only reason I got the MSD coil on my 280z, was because I started to have a misfire problem on the way to California a couple of years ago. Spark was very weak, so stopped in at local Parts store and bought a new coil. Only thing they had was MSD. Turns out it wasn't the problem.....

Nope... filled with oil. Notice how the factory oil filled coils are mounted horizontally. Think about that. Some coil manufacturers ( MSD is one ) save a few pennies by not filling the coils to full capacity, allowing air bubbles to form. Factory Nissan coils and other high quality coils ( Ahem Crane ) are filled to the proper amount of oil with just a very small space for expansion. They are not sensitive to mounting position. Doesn't hurt to mount them vertically though. Many, Japanese cars have oil filled canister coils ( Hitachi, or Nippon Denso ) mounted horizontally. So do Mopars with stock coils. Chevies and Fords mount canister coils vertical. On vintage German cars I have always seen the coils ( predominately Bosch ) mounted vertically only. Note to self: In fact, I have an MSD Blaster 2 mounted in the stock position on my 280Z ( Horizontal ) . Because it's MSD and those DO fail when mounted horizontally, I am going to change the mounting position. BTW, I just looked up the some Tech info in the Crane catalog, and all of Cranes canister style coils are oil filled. They are not E-cores. PS20 ( Black ) and PS40 ( Nickel plated Chrome ) have 1.4 ohm Primary. 5.2 Kohms Secondary, 7.5 mH Primary Inductance, 26 H Secondary Inductance, 60 to 1 Turns ratio . They are suitable for all points and OE Electronic ignitions. Crane HI-2000, HI-6500, XR700 and XR3000. C.A.R.B certified. PS60 canister coil has ouput characteristics similar to Crane PS91 E-Core. It cannot be used with points ignition. Compatible with all OE Electronic ignitions and the Crane HI-2000, Hi-6500, XR3000, HI-6, and Hi6S. Can be used with XR700 if an additional ballast resistor is installed.

Ah... I was thinking more long term storage.

Have never liked Michelins. They last a long time. But they do that by turning into granite as the tread wear gets below 50%. Horrible in the wet on used Michelins. Here in the PNW it rains a lot and you need a tire that stays grippy in the wet and cold. I've taught HPDE, and the worst cars to drive in the wet have always been shod with semi worn Michelins. The new Firestione Indy 500 ( Do not confuse with the older Wide Oval Indy 500 ) is getting rave reviews on Tire Rack. It's now rated #1 by customers in the Ultra High Performance class. Mind you, take that with a grain of salt as it's a fairly new tire and the data sample is fairly small. However, it's still getting lots of 5 star reviews. It's a re-branded Bridgestone...which is good.

You can safely use the Datsun factory resistor. The reason for the ballast resister is to lower the amperage draw through the points. But there is some varience allowed.

Ah.. gotcha. I had a set of Hankook Evo S2's that liked warm weather as well. They were useless in the rain or when the ambient temps got down.

" Invisible " Scotch tape around the battery terminal lugs. Trust me, That confuses the hell out of people. Even a jump start won't work. Tape both positive and negative for added frustration. Thief ain't gonna hang around long... Quick, cheap and simple.

Thumbs up on the Crane Ignition parts. I've heard that Fast EFI has purchased all the stock and production rights from S&S Cycle. ( Crane went bankrupt after the 2008 crash ) . I wonder if Fast is getting new production made in the USA or out sourcing to China. Might be best to purchase NOS or used on Crane stuff till that question is answered. Summit and Jegs still have a fair bit of NOS Crane Fireball parts on hand. I've used Crane ignition products since the mid 90's. Very high quality parts. Put MSD to shame when Crane came out with the HI-6 CD box. Cranes E-coils were also the bench mark when they came out. Still are.

50 degrees? The Direzza ZII Star Spec says not to be run at or near freezing, but 50F?? That doesn't sound right. Quote from Tire Rcak:

Glad to help. Georges is a great guy. I've known him for years, decades actually. Met him at WestWood way back in the late 70's. Do you know Andy Paerson from Specilaty Engineering? Another great guy and Datsun expert. We'll have to get together and cruise out to Mission sometime. Are you a member of the BC Z Car Registry? It's been inactive for a number of years but has been revived . I also do cruises with the local 510 club. Huge Datsun knowledge base out here. A lot of the local Z car guys frequent http://www.the510realm.com/ Richard Boyk
