Yep, have put SS springs in with Comp Engineering shocks (50/50 rear and 90/10 front) The track was atrocious. With the 255/60/15's M/T ET Drag Radials I couldn't get traction. Just constant wheelspin and even down the track as well. I've got the new 275/60/15's that I'll put on next time out. It ran 106mph and that's with bucket loads of wheelspin and I ran into fuel issues as well. Was stalling on me after the burnout on each run and then at top end thru the traps it was burping and spluttering like it was starving fuel. I didn't get one clean pass in all day and it was 95 degree heat all day. I've got to get the fuel issue sorted.
