We have a 3 link and we're allowed to run coilovers on the rear. The problem is through the corners I can't even think about touching the throttle until I'm almost completely through the corner.
The track is a paper clip 3/8, with medium banking, long straights, tight corners.
The car has both coilovers mounted solid in front of the axles, with a spring bar and 90/10.
Specifics:
57.8 Rear 53 Left Full fuel, w/o driver
70-350 lbs Bite, (we've tried it all)
200# w/ 93 LR, 175# w/ 95 RR
650# w/ 75 LF. 800-900(tried both) w/63 RF
600# SpringRod 15* down, 90/10 20* up
J-Bar w/ between 8 to 15" Split.
Total car weight 2400 complete, w/o 245lb driver. (We have to weigh 2500)
LR Trailing arm 10*&22*, RR 10* & 25*
After 4 different shots at this, trying to make it so I can pick up the gas earlier and through the corner, we are about to change the mounting on the RR to have the Coil over behind the axle.
Suggestions? Do you think this will help? Other theories, comments appreciated. Need more info? We are beating our heads on the wall trying to get this thing faster, and we are at a loss.

moving rr behind rear will help lower your left side to 51.5,if your driver weighs more than 150lbs. use 51.0%leftkeep lr bite 40 to 65 lbs.and put as much angle as you can get in your pullbar.

May also want to try lowering the 90/10 on the chassis as that should help to tighten the car in the corners..

Just my experiences....

move 200# spring to right side & 175 to the left. this will give more left rear bite & git the car of the coner. move right coilover to the back of axel.

What happens when you get on the gas? Is it pushing or loose? Are you going in deeper than the guys you run aginst? Are you pitching it to get it to turn? These things gotta be considered befor you start making changes.

Typically I drive in deeper and flick it, but with this condition I have been easing it in very gently to try and help my exit. We have had the car pushing in and loose in, it doesn't seem to make a difference on exit. If the car isn't straight, it wants to spin with throttle application, and quickly. When it gets fairly straight, it's a rocket, but I can't carry any speed through the corner. (when on the gas, the whole rear of the car hikes up pretty good, it just feels like you can't lay on the right rear through the corner)
We have put the spring behind on the RR this week, so hopefully that'll cure it. But I'm still open to suggestions and have given a lot of thought to the advice given so far.
