my 90 gt has almost a road and track box, its missing the panhard bar, solid steering shaft. my cars parts list:
* MM Road & Track Springs
* MM Caster/Camber Plates
* Bilstein HD struts
* Bilstein HD shocks
* Front and rear Urethane Spring Isolators
* Urethane Pinion Snubber (solid axle Mustangs)
* Griggs lower subframe connectors
* MM 4-Point K-Member Brace
* MM Extreme-duty Rear Lower Control Arms (adjustable, w/sway bar mount)
* MM Solid Steering rack Bushings
* Front Swaybar bushings
* Front Swaybar end links
* Front control arm bushings, urethane
that and a 5 lug swap, and new upper control arm bushings, poly motor and trans mounts, and all new moog balljoints and tie rods.
car handles great. i actually havent turned it as hard as i think it will go, since entering a turn much faster than you should is a different experience. but it handles like its on rails. not like a built corvette or M3 (they have immaculate geometry) but enough to be fun.
