  1. I don't spend a lot of time on message boards lately, but found this thread and wanted to update folks that we have responded to the issues found with the WCR CV axle design. FutoFab CV axle kits are not just a continuation of the Wolf Creek Racing (WCR) design, they are significantly revised and improved FutoFab product. The first way to identify the change is the ORANGE axles. FutoFab acquired the rights to the WCR CV axle design and has made several changes and improvements to them. Our most notable change is the introduction of a second, larger and stronger axle kit for higher horsepower cars based on the Porsche 930 Turbo 108mm CV. FutoFab Type 2 / 100mm CV Kit Improvements We use the same CV size as the original WCR axles, but that is about the only similarity. The following are improvements we have made to this axle kit. The CV bolt holes are tapped directly into the adapter allowing use of LocTite. WCR used Helicoils in their adapters which can back out and cannot be used with LocTite. Our CV Bolts are now grade 12.9 - M8x1.25 socket head metric bolts. They are drilled to use safety wire, which we still strongly recommend doing. We use a torque distributing washer under the heads of the CV bolts to spread the clamping force. Each washer spans two CV bolts. The CV bolt lock washers are now a SCHNORR washer. They have a cone shape with one-way serrated surfaces for a greater locking force than the original lock washers. Since making these changes we have had zero complaints of the CV bolts loosening. FutoFab also changed the outer CV adapter design to help keep the bolts that attach the adapter to the companion flange tight. FutoFab's outer CV adapter has slots that captivate the head of the bolts that hold the adapter to the companion flange. This allows you to check that the bolts are tight (and tighten if needed) without having to remove the outer CV from the adapter. Noise Reduction and Improved Driver Confidence One of the biggest complaints FutoFab received about the WCR CV Axle design was the excessive amount of rotational freeplay within their system and the clunking noise it created. While operationally solid, it did not instill confidence that the WCR CV Axle was durable. FutoFab addressed this by minimizing the amount of rotational freeplay to nearly zero. And as a result, axle strength increased as well. We changed the CV’s to ones that have tighter internal tolerances. This decreased the CV’s internal free play to the absolute minimum. Our axle bars are now made from a larger OD, heat treated 4340 chromoly steel with custom machined splines. Each axle end is custom fit to the CV spline, further minimizing rotational free play. By using custom made axles we added a hard inner CV stop machined into the axle. This eliminated the inner C-clip and groove that WCR used. This change makes the FutoFab CV axle much stronger than the original design was. Detailed Comparison - FutoFab Type 2 / 100mm & Porsche 930 Turbo / 108mm CV Axle Kits: While both axle kits use the same basic design, they are unique in most every detail.

The targeted horsepower numbers are offered above as only a guideline and in no way are to be construed as a guarantee of our CV axle kit’s capabilities.

  2. FutoFab will have spaces at Carlisle near the end of Aisle B. While most of our stuff is 510 related (steel reproduction fenders, valances, rockers, aftermarket sway bars, aluminum LCA's & TC Rods ) We will have our Z car adjustable aluminum LCA's & TC rods. Chrome F&R 240Z bumpers, amber directional (JDM style) 240Z tail lights with us.
  3. The tail lights we sell are complete units with harnesses (all you need is bulbs). They have the chrome trim, come with bolts and a light duty foam gasket. What you see in the picture is what you get. The connector is 4 prong connector, no rewiring, plugs right into the US market 240Z harness.
  4. Yes, that is correct FutoFab is holding a Cyber Monday Sale. 15% off all online orders except wheels (wheel purchases will include free shipping to anywhere in the lower 48). It will be all day Monday December 1st and ending at midnight on the west coast (12:00 PST). More details will be posted to our website.
  5. FedEx should have the bumper to you tomorrow.
  6. We use FedEx on our larger parts. We have a decent rate schedule so shipping doesn't get crazy. Without doing an actual look-up I'd say around $30/ea S&H. If anyone wants actual shipping costs, the bumpers are on-line for ordering. Set up your account, put the parts in your cart and head for check-out. The actual shipping charges will calculate before you pay. Custom colors could be arranged, but it would be done with my local powder coater. He would have to strip the part first and then recoat it. Likely less than a chrome bumper, but not by very much.
  7. Prices are for new bumpers, not for plating cost or a rechromed OE piece. They are 100% brand new parts. The quality is exceptional. The prep and chrome work is better that OE. I am not sure on the powder coat sheen. I have not seen a sample of the bumper in black. I'll post as soon as they arrive.
  8. Zup, FutoFab has '70-'72 240Z steel F&R bumpers coming November 14th. Available in both chrome ($360/ea) and black powder coat ($240/ea). Ordering is now open. These are JDM style w/o holes for rubber face strips. Pics of a '70-'72 240Z chrome front (black powder coat is made the same).
  9. Gary, Adverse wear on bearings is not a direct result of using spacers, but more a result of the effective wheel offset the spacers create. As an example, a +0 offset is considered by most to be the correct fit for a 7" wide wheel on a Z car. If you have 15x7 +0 wheels and add a 25mm spacers you end up with an effective wheel offset of -25. This will add more load to the wheel bearings. Now if you have a 15x7 +25 offset wheel and add a 25mm you end up with what is effectively a +0 wheel offset, which is considered "perfect" by most for a Zcar. So to say spacers alone create excess bearing wear is kind of a misleading. What does create bearing wear is when spacers change wheel offset and add to the car's track width (and the jury is still out on exactly how much added track width will cause excess wear).
  10. FutoFab, working with Motovicity can supply Tokico shocks for your Datsun. FutoFab currently has Illumina BZ3038 strut inserts in stock (280ZX fronts) and has access to all the Tokico products Motovicity stocks. Please feel free to make inquiries.
  11. One item to note on appearance. All 15" Retro 4 wheels look exactly the same on the face because they are all cast using the same outside mold. Whether the wheel is a 15x6 +24 or a 15x7 +0 they all have the same lip depth and spoke shape. The difference is in the thickness at the wheel center and the width of the mold used on the inside to adjust the wheel width. The offset is determined by the amount of material machined off the hub surface of the wheel. The only visual difference between a +24 offset and a +0 is how far in the lug nut recesses into the face of the wheel.
  12. tlorber, Retro 4, 15x7 in silver comes in +12 & +18 offset. Sorry no +0 in silver, black only Lemans 15x7 in gray does come in a +0 offset. Here is a customer's 240Z with silver Retro 4's, 15x7 +12 offset and 205/50-15 tires.
