OK here we go. Got a 4/4 spring behing shock in front lr, spring in front shock behind rr, both on sliders. Chevlle front stub. 1/4 mile banked track always slick. Car is always loose no matter what we do. Cars loose in but driver likes it like that to a point, loose in the middle and spinning tires like crazy on exit. I'll try and give as much info as possible. Scale #sLf-497 Rf-485 Lr-705 Rr-606 Rear%-57.2 Cross%-51.8 Left side-52.3 All numbers are WITHOUT driver. Springs: lf-700 rf-800 Lr-200 rr-175 Shocks, bilsteins.Lf-30/50 rf30/50 Lr-30/50 rr-30/30 JBar 7 3/4 up on frame, bottom hole on pinion 9in. Pull bar bottom hole on frame- 18 degree of angle, can't remember off hand on spring rate, moved slightly to left on rearend .RR leading by 3/8 Tire pressures. Lf-8 rf-12 lr-8 rr-10 Lrb 27- 46 at full drop. Llb 3 Rru 12 Rlb 0 0Last night bottomed out lr shock in the heat, changed the rf spring to a 650 and scaled it at the track and went with 74lbs lr. The car was absolutely terrible, no drive off and looser then before. We won a month ago but since then we had been lacking forward bite. We won with a 650 lf 700 rf 225 lr 175 rr but car was still loose that night. We are pulling our hair out and tempted to go clamped up zlink. Hoping to get pointed in the right direction. Thanks guys.
