What are your ride heights and spring lengths? I assume you're running a nose piece with a tube bumper and not the heavy stock one. Get the seat and controls as far back as you're allowed. You might look at hiding blast in the rear frame horns. I've seen guys use round bar stock instead of tubing for rear down tube braces. Secret ballast!

That's a $#it ton of bite! I'd put the #200 spring back in the LR. Probably turns in great with the left rear dragging.

Ok will do, what is a good # for bite? It also seems like left rear picks up in the corner, thank you for your help and knowledge,I appreciate it!

I try not to go over #130. But it depends on the track condition and driving style. More bite will help the car rotate on entry but cause the issue you're having with a push center-off. I'm running 105# of bite right now with a 1" spacer in the LR. If I pull the spacer I get 125# of bite.

Those are pretty restrictive wheel and spacer rules. Have you checked the stagger on your tires? Maybe run very little stagger in the front and as much as you can get in the rear. You should be able to fine tune it with air pressure after that. Otherwise I would run 4" offset wheels on all but the RR. Run a 3" there. What tires do you run? We run asphalt pull offs and I don't go more that 16# of air pressure in the RF.

Ok. So youre running quite a bit of air pressure then. I'd still air them all up to the highest pressure you run and check the rollout on them. You probably won't get much stagger though. Other than that you could add a little weight to the right rear of the car or swap your front springs and go with reverse split. That'll take a little bite out of the car also. Quite a few guys run like that. Especially if your track is smooth and slicks off by the feature.

Ran the car but only in the heat,got rained out, but started in the back and finished 2nd, was a lot better but didn't want to turn mid corner,I think because it was so slimy,gonna swap springs around in front and give another try,but your help has made it 100% better couldn't thank you enough! Let you know how it goes!😃

Right on! Glad to hear it and glad I could help. My car was good Saturday night. Got dumped in the heat race though. Passed 4 cars to get the last transfer out of the B. Then it got real hot after 4 laps in the A.

Also. If your track gets as slick as the one I run by the feature. You may want to hold off on the changes. As the track slicks off you need a tighter car to turn. Otherwise you'll have a hard time keeping the rear from coming around. It took me a while, and some stearn coaching,to figure out that I wasn't driving the car in hard enough to get the weight to transfer to the right. Car always seemed push like a dump truck mid corner. Now I drive it in as far as I can until it feels like the rears going to come around. So much more fun! 😁
