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).

Just curious what are c4's weighing in at in full road racing trim? How much tire can they fit? I've seen a few TPI c4's go very cheap w/in 250 miles, a little tougher to find an 89 or 90 though. I've been really tempted to go that route with a 408 sbc sitting in my garage that just needs freshened up.

They fit 315's on all 4 corners with 17x11 50mm ZR1 wheels, or 335's on all 4 with custom wheels with just the right offset. This is with no fender mods, other than some very minor rubbing at full lock on the inner front liner.

My C4 weighs 2876 on 17x11's with 4/5 tank of gas. No cage, no interior, doors are untouched though (door bars, power windows, locks, etc).
