Last Sat. my car was loose on a dry slick track. Surprise surprise, but I went under a guy to pass him & he cut me off. I got my left front all the way on the inside berm & the thing took off like a rocket! I ran every lap after that on the berm & kicked some **** . I run 80# of left rear bite with a 225rr & a 250lr. My Q is do I need more rr weight? would swapping the rear springs work? May be a dumb Q ,but I was thinking the berm under my lf was planting my rr. Do any of you guys run more rr weight than lr?
77 monte 3400# 53% rear 49% cross 52% left.
Thanks guys.

53% rear on a 3400# car? wow! i would say that you do not need more rr weight, i wouldn't swap rear springs either. you said your car was loose, as it should be with that setup. you need to bring your cross wt% up by either stiffening the lr to a 275 or dropping the rr to a 200. your car is so heavy on the rear end you may have to do the 275 change.

I'd bet it was more of a case of finding a better track on the bottom than a setup issue,unless the more weight it was putting on the left front helped the car to turn thru the middle.More right rear is usually a no-no on a dry track.

Im in the process right now, of running a setup real similar to that. Im running 3400, 54 rear, 54 left, I start out the night running a 275 left 250 right, in the mud, as the track drys out, I have been softening the left rear spring but making the sure the same bite stays in the car, pair of 250's by the heat, then down to a 225 in the left rear by feature if its real slick. Im running about 70 pounds of bite all night long, with 2 to 3 inches of stagger. I found if you keep the rear split no more than 25 pounds it works. 50 or more upsets the car to much on slick track.

How much does Hot Laps pay at your track ?
You change springs between getting there and the heat. Big pit crews are a good thing.

Whatver man, I use hotlaps to try things, not ride around and wave at the crowd, little pit crew, we just do it. It aint hard, its just the small things that make a race team successful.

And by the way if you do decide to try something in hotlaps bolt on the feature setup I gave you, and if its muddy and it pushes real good, take it back out for the heat and put it under it for the feature.

I agree with rico 08, the track probably had better bite down there. However, if you think it is loose in the middle and you need more side bite, you could try moving weight up in the car, or decrease your cross weight just a bit.
