Since I don't street race the car:
HpTuners, Qa1's front and back with a 300 lb front spring, Moroso fabbed valve covers, throttle cable direct from pedal to TB, Hooker Super Comps, 1 Chambers dumped at the rear, UMI subframe connectors, UMI lca brackets, Midwest Chassis moly short ta, Spohn double adjust panhard, LG aluminum double adjustable lca's, Auburn Pro, TA girdle, Motive 3.73's, ARP studs all around, 15x3.5and 15x10's, 275/50 MT DR's/ET Fronts, MTS level 4 trans, TCI 4k, aluminum driveshaft, LS2/FAST 90, 90mm lid, Z06 MAF, chrs1313 ram air, bumper supports/insulation/ac/ps/battery/half of the speakers/spare/back seat(no metal cut out)/fog lights/cruise control/traction control, door bars are still in it, lighter Firebird hatch, stock rear sway bar/no front sway bar, b&m trans cooler mounted infront of the fog light hole. I changed the shifter knob because I can't stand the size of the factory trans am piece. Soon to go on are the heads/cam setup I have on the bench, ASP pulley, and I wanna hit it with a nice shot. The car will also be getting a UMI drag bar over winter. I don't know if this is accurate or not, but Rt. 66 scales had me at 3370 with 1 leather seat, and maybe and 1/8th tank of gas. I'm 285. The car still has alot that can come out.
I don't think i'm forgetting anything.
