I am going to fabricate a straight pipe from the last cat back to shave some weight since I can only add exhaust from the final cat back. The biggest handicap is I need to run the stock size wheels with the only variance allowed being + or - .25 of an inch offset. I might run the 225/40/18 front Hoosier and something less sticky on the rear since I am stuck running 19s on the back.
Upgrading the front sway bar to SRT specs. on this car is only going to help eliminate the large amount of front body roll and stiffen the front end, it's not going to create an understeer situation. Because if that were the case, all the SRT6's would have understeer. If you adjust the camber -1.5 to -2.0 and run a lower front tire pressure you'll definitely not have any understeer.
Since you have to stay with the OEM wheel sizes, forget the idea about the mix and match Hoosiers for now and go with Michelin Pilot Sport Cups (heat cycled). They have 18" + 19" sizes. Or, you can try the Toyo R1A. Good luck with your Auto-X.
PS: the biggest handicap you have is that you bought a Crossfire... Just kidding...
