I have done the ecu from InMotion, the TVT cai, bigger injectors, Magnaflow exhaust, Sprint Booster, and find it is a whole new car.

I also did the H&R sway bars front & rear (rear is a ***** to install) and went to Vredesein tires (275/30 rear, 235 front) and the handling is more neutral and tighter/flatter.

Went to drilled/slotted rotors and Porterfield "S" street/track pads, ss brake lines and "Blue" racing brake fluid and find the braking is better, more predictable at the limit (I run NASA street class eents at PIR and Firebird here in Phoenix).

Fun car !!!
