Ok, need some advice and edjucation here. Have a DW8 with plug and short LR trailing arm and long RR. LR arm in top hole with RR in second down from top (about 7% split). 0 degrees of rake in J-bar at lowest position connected to right side of pinion. No rear ballast. 20 gallons gas. Don't know rear spring rates due to springs were in car when bought it. Tire pressures were LR-11 and RR-12. Can't remember chassis percentages.

OK, track is flat 3/8 with sweeping turns. In hot laps, track was slicker than whale snot, but handled track ok with both trailing arms in middle (LR) or 2nd from top (RR) holes. Wanted to put more bite in car and raised LR trailing arm to top hole. Didn't change tire pressures. Track blacked over (slick). Could not drive car in heat race. Kept rolling over on (RR) sidewall. Should I have increased my (RR) tire pressure? Am I running it to low? Any legit suggestions will be greatly appreciated. Thanx in advance.

12 lbs in RR should be fine. Most everybody I know runs 10 to 12lbs in RR. I have even run 9 in my RR at times.

Did the track take rubber? if it did the traction probaly went way up and you didnt need the roll center so low in the car (rear). Raisong the panard bar and putting some angle it would of helped, and or high RR tire pressure. Running Hoosier's? or American's?

WE RUN AT LEAST 13 LBS IN ALL TIRES ON OUR DW-8, AND UP TO 20 LBS IN THE RIGHT REAR.
I WOULD RUN THE BALAST ON THE RIGHT SIDE AND INCREASE THE TIRE PRESSURE TO CARRY THE EXTRA WEIGHT. A SMALL AMOUNT OF ANGLE IN THE PANHARD BAR MAY ALSO IMPROVE YOUR FORWARD BITE ALSO.

Yes, the track did take rubber from all the late models, etc. I had my roll center down low to loosen the car up through the corner since it's felt tight since I've had it and could never seem to hang out (slide) the rear in the corner. I was hoping to take some chassis loading/roll off that tire to make that happen. Did I go about it in the wrong direction? Oh, I'm running American's.
Dirtywrench13, I'm not running any ballast in the rear, just fuel weight which puts me and the car at low 2500lbs and enought weight for fuel burn off.

Sounds like it, raise the panhard bar up on the frame side when the track takes rubber to get some side bite out, and FWD bite in.

If your running it flat now, does the car lean / roll over alot on the slicker tracks? if it did, i imagine it was bad when the track took rubber.

Try running the panhard bar with some rake in it, angles down towards the ground, from the frame side.
