I have had the Qa1 coilovers on the front for about 1000 miles now, i bought them used from whitey, a board member and friend. they have less than 3500 miles on one, and the other (drivers side) has less than 1200 miles.

I have adjusted the spring height until 3 threads were left on the shock, and i have adjusted the shock dampening (as far as +9)

some things working against me are the Spohn Long tube front tq arm mount, and custom Y pipe, it is lower where the fuel lines are on drivers side. But overall have standard Long tube header clearance.

The car still bottoms out on road dips, crests, and some highway bridge gaps (where hwy goes to short bridge and back) i wont even bring up speed bumps.

Before the QA1 (stock setup 100k miles) only the spohn tq arm mount hit the road, NEVER like it does with the Qa1's, and only at low speed.

Does anyone have any thought to this? i have stock rear WS6 springs/shocks.
and i am planing to replace them with the spohn QA1 rear coilover, to stiffen up the rear setup.

does anyone think this will help my current issue? or make it worse.

i have read many many Qa1 adjusting threads/papers, and i am just looking for some first hand application info. fred...?

thanks guys.
