Strip the car completely down to the essentials, put in a 6 point cage, cobra
evo seats, harnesses, PFC 01 brake pads, champion RG5 18" wheels, Hoosier R6 tires, Moton suspension, H&R sways and call it a day. It'd probably pretty easy to get the car down to less than 2500#s with little more than elbow grease. You'd be as fast as nearly any street car on the track.
