Also, driver skill goes into it A LOT
My 2+2 has
250ish treadwear 245's up front and 275's in the rear
Bigger 3rd gen front hollow bar
CPP adjustable axle mount rear bar
Viking double adjustable on all 4 corners
Moog 5660 (too soft) up front and 5009's (I think) in the rear,
Foam zq8 front bump stops
Tall lower and tall upper ball joints and MCAR adjustable upper arms for added camber
Heim end rear control arms from trick chassis
Rear torque box bracing from trick chassis
Most of the stuff is to get the car to go launch consistently with a blower and stick
And 550+hp
And it's way beyond my ability to drive to the level at an autocross where it's the car's fault for not going faster.
$500 for an afternoon driving school will probably net you more than $500 in improvement from parts. I have seen damn near bone stock MCSS's with just some decent treadwear 17's performing as good as my car at the autocross. They just know how to drive.
