I have ran 1/4 mile and 3/8 mile dirt tracks for 20 years, what are you running car wise and spring wise now? what set up is the rear end?

I had my car set up by a guy whom won several championships in Montana, he put the following springs in my car. LF 700, RF 800, LR 175, RR 150. As you can see you are not far off. I would try the springs you have now and see how they work. If you can borrow the springs that I suggested, try them too. but you may not need to purchase them. I hope you can borrow them and see how they do I hate buying something then finding out it won't work. I ran the same springs in Rapid City at the WISSOTA western 100 and they worked O.K. I could run the low grove very well, the high groove was loose. (i spun) Rapid was a 1/2 mile track. At the 3\8ths mile tracks I ran well too, however I think there was room for improvment. And I don't run the same kind of rear you do. I just had a regular 4 trailing arm rear, nothing fancy but the car was an old factory car from North Dakota (the name escapes me). Overall, I would say I bet not, but testing will give an answer that you can trust.
