    Its official MK I GT40P 2426

    Cold they have little grip- you are right about that1 I had an interesting phone conversation with the chief compounder at Goodyear Racing Tire Div many years ago. I forget his name- he was British fellow. At that time the optimum tread temperature was 190F.

    Race tires aren't too bad cold but when the compound is hot, they are like glue.

    Fastener Information

    I didn't mean to promote them, only show how scary vibration can be and how ineffective some of the stuff we've been using for years can be.

    Fastener Information

    I'm not recommending Nord-lock , in fact I've never tried them. This site does have some good information on how fasteners can fail due to vibration. The results are surprising. Another site has more information and videos of vibration tests...

    Wiring-Instr Panel (aka Dash) Guages

    I'd recommend shielded cable. If size is a problem, use RG-174/U coax cable. the shield is the ground return. Even better is RG-188A/U. It is Teflon so it can withstand much higher temperatures.

    Steel welded frame vs Monocoque

    "The Italian gearbox couldn't last with the power & torque of the V8, ..." True. It didn't prove reliable in the Mk 6GT Lola, either. The ZF was a big step up.

    Exhaust Finish

    Cerakote is what I used on my long-tube headers. It has held up well. BTW, black has the highest temperature rating of all the Cerakote colors.

    John Horsman told me that JWAE researched many airfoil profiles in the MIRA wind tunnel and in the end found that the NACA 4412 was the best overall.

    I think "KOK" is a Korean brand.

    Scratch build MK IV

    If that chrome-moly was a grade called "normalized", you do not need to heat treat it.
