Hi, everybody. I'm really excited to go for an all out track car project.

I'm really puzzled at this dilemma: could a 98 Z28 be modded to match or surpass the handling of a C4 with Z51 like susp (Crossmember and camber brace mods)?

I may be able to trade my 98 LS1 Z28 for an auto '95 C4 (and like 3K of cash, and I would swap a ZF6 and mod susp). C4s are not so cheap to get in my country (as opposed to fbodies), let alone C5s. I was just about to swap a T56 (with relocation crossmember, Z06 clutch, etc) on the Z. Before I just do either of it, I want to make sure to know if I can achieve handling capabilities of a Z51 C4 or close through modding (shocks, tires, rims, sfc, kmember, a-arms, torque arm, lcas, panhard, strano swaybars, rollbar, a little diet, etc). Guys please be honest.

I've seen biased opinions on the C4 side by people who do not really focus on track improvement (and take stock form as a reference) so I thought this would be the right place to ask.

I want to make sure to invest time and effort on the car with better handling potential (modded) on the following couple of years. (Ultimate purpose: Road Racing and a little of AutoX).

This goes back some time. But in 1999 there was a category in ProSolo that pitted ESP cars against stock class C4 Corvettes (don't recall if they were AS or SS classed at that time). But they were both very, very competitive with each other. I beat Matthew Braun a number of times in my '91 (which is in no way as fast as my 2001). But lost the Championship to Gary Thomason.

Point being if an underprepped ESP 3rd gen (11's w/R-comps, headers, good LSD, shocks, but not much else) can run with a stock class (meaning shocks, bar, R-comps) what do you think a much more prepped, more powerful 4th gen can do?
