I attended the Charlotte Auto Fair this weekend and talked to a custom solid axle builder. He said his 12 bolt rear (cast housing), hub to hub with Wilwood brakes would weigh about 250#, that does not include springs, shocks, linkage. 8" with fabricated steel housing would be about 20# lighter. Would still be curious as what your's (red L98) weighs.

It's kinda funny. You got some guys who spend tons of money trying to make the car handle and corner better.

Other guys swap in solid axles, manual racks, etc.

I like the idea of a fast C4, but if you want race car I think you should build a Vega. Not to say there isn't a lot of fast (10 second) C4's in full race trim, but is it still a C4?
