Prepped track may allow lessor suspension, tire/wheel setups to work but marginal surfaces will require all the help we can get or at least is the case with my positive displacement FI/nitrous setup. Drag radials both MT's and Hoosier 315's did NOT work on stree....t. Bias Ply so far has been the key. Know your surface. Let some wind out of the tires till they dance, Don't be stingy with the VHT, lay lots of rubber down and smile

Thanks for the link. I believe the QA1's fronts are 250 lb. but only 9" long according to the rep.

This thread just kind of died. Any progres on this?
I'm pretty sure with this coilover kit, you can easily fit a 12 inch long spring for more stored energy. They send a urethane coil spring spacer with the kit to fit the shorter 9" 250# spring. If you jack up the front of the car you will see a full 3 inches of slop between the top of the spring and the upper spring seat with the ride height adjuster all the way at the bottom. You'll probably have to weigh the car to get the proper rate, but I'm guessing a 12" spring around 200 ish would be a good starting point.
Thoughts?
