The best handling road course Mopars out there have factory based suspension...
This one is NOT one the top handling cars, but was pretty good. This run was also with a failing alternator (hence the need to refire at the end of the run). Nearly 2 seconds quicker on this course than a turbocharged WRX and a supercharged Jag. We put this together ON THE CHEAP, too.
In your opinion, what's the best "fixes" for the OEM suspension? Sway bars and larger brakes? Custom leaf springs and larger torsion bars?
The stock chassis seems to do well when properly sprung for the task, but still responds well to chassis stiffening, reinforcement, and some sort of traction bars to prevent wheel hop...
