John, as usual, brings up some good points.
As I recall, the GT6 springs are already substantially stiffer than the
Spit's springs (to handle the weight difference). In my street GT, I've
gone to coilover's in the front. One of my better moves. If I can ever
get my comp springs and shocks back, the springs will go into the GT.
Coilover's for the back would, in my estimate, also make a HUGE
difference. I've put some serious thought into crafting a road race
legal full independent rear conversion for the GT chassis. It wouldn't
be especially hard (replace the spring with an A arm and put in a coil
over, perhaps even move the coil over from the stock shock location with
a rocker arm.)
Should be an interesting ride.
