    U_joint on wheel side cv joint on diff/gearbox side

    You wouldn't put two U joints out of phase with each other - that would double the amplitude of the velocity variation end to end. Keeping them in phase means the output shaft and the stub axle remain at constant velocity, while the intermediated shaft has velocity variation. Which is somewhat...

    New Transaxle Comparison / Discussion Thread

    My guess is that the transaxle is going to be pretty big, both by dimension and weight. Fitting it underneath a GT shell may be difficult.

    CV joint removal

    Gents, I need to pull apart a 930 CV joint to press a reluctor ring onto the CV body. I took a cursory glance at the area where the circlip retains the axle within the CV, but it's covered in grease so I can't yet get a detailed look. Before I tear into it, it would be useful to know whether...

    Paddle shift for H-pattern gearbox

    A big part of me wonders about the appeal of these systems. Any retro car like a GT40 or Lola T70 is fairly un-aero, so it will not corner as fast as a modern full bore track car. So why even bother trying to use a system like this to eek out a second a lap when putting real aero hardware on...

    Staggerd wheel set up verses square

    equally, putting a 275 on the front of a GT40 may result in not enough heat in the tire to make it work. Unless you do some aero mods, a GT40 will have lift at the front. A big tire will only make the problem worst. Ultimately, race cars run tires that make them as fast as possible, and...

    shifter cables needed --- gt40 mkII

    ^ yep. Had a set made in Europe from a very highly reputable firm, and didn't love them. Had the above make a cable for me, ended up being cheaper and a lot better - less slop, less friction.

    mastershift paddle shifting issues. . .

    others may chime in, but as I remember it the Mastershift forces the shift very hard and may destroy synchros. I would research it before committing to its use.

    tubular or monocoque ?

    agreed - if authenticity is a prerequisite for tracking/racing, then you don't have a choice - mono. If not, space frame will not require as much shop equipment/overhead, will be easier and cheaper to build a strong and reliable chassis, and it will be more easily adapted/repaired as situation...

    Mid Engined Citroen DS

    ultra cool project, I've never seen anything like it. One concern - the rear track is very narrow, combine that with the mass of the motor moved to the back and I wonder if the platform will have roll control problems when driven with vigor.

    Here's a loaded question: Which engine would be best for an RCR build?

    seems to me that at $10K, you can find a G50/50, or a G50-86(?) which are pretty capable transaxles. Unless you are running slicks, 500lb-ft should not overload the trans, since normal street/R compound tires will break loose before you hit peak torque in low gears.

    Mendeola vs G50/G96

    did Quaife get their design/quality issues worked out? They had some cracking problems in the cases, and there was some question about their ability to deal with big V8 torque. I don't have direct experience with this, but i remember there were definitely issues.

    Aftermarket shifter options?

    agree with the rec on cables. I set a cable shifter up using a well known, high end brand and ended up with something that had too much slop across the gates. Changed to one from Control Cables in CA, and it improved dramatically.

    The season gets started.

    Graham, if you were racing on looks alone, the race would be over before it started! About the sexist car ever... FYI I sent you a PM if you have a second. Tom
