What do you have done to your track car?
Suspension, tires, brakes,
Driveline is rather stock Yamaha motor, 5 speed.
He spends all his money on the tow vehicle 
Yeah, I figured… I meant what specifically, I used to have a 5-speed '95 SHO. I haven’t seen his white 1G in person yet.
suspension: koni/eibach Gen 3 subframe with all new bushings. BMR rear arms, H brace. factory 24/26 sway bars with new bushings.
brakes: 11.6" fronts hawk HT-10 pads rear brakes have seized calipers so the rear rotors were only slightly warm after a session
tires/wheels: 2 piece 17X8 rims kumho XS tires
drive train: quafie LSD with 240K transmission with a slowly failing 3rd gear syncro. stage 1 pressure plate, napa organic clutch disk, 8lb alum flywheel, engine is completely stock with fresh rod bearings.
there is some money in this car but it is such a pleasure to hammer on at the track. eventually it will get a M90 blower and a exhaust. all depends on how the turbo kit that shosource is building turns out. I am at a point that I would rather buy something than try to make it.
