I'm running a carmaro street stock and I have the 2-link swing arm setup. We have springs that go, LF 600 RF 800 LR 250 RR 200. The shocks are 75's in the front and 94's on the back. We only had 48% rear, 56% cross, and 53% left. I know my cross and rear might have been a problem. In the middle of the corner the car got really tight and pushed all the way through. The car got alot of side bite, my scout said the left front wheel came a foot off the ground. I really need to know how to loosen up the car.

Thanks

schoonr can you get another inch of stagger on the rear? If so scale the car & see what the wheel weights are then add the stagger & reset the wheel weights.This will keep the bite the same & the added stagger will help the car turn at middle & off.Try this one change & see how it works,then if it is still tight you can take some bite out or change the R.R.spring to a 225# an this will help.Do only one thing at a time. cd2

I know it's just a different way to saying or thinking it, but I'd rather find a way to get the front to grip more. That being said, I would go up on the LF spring, maybe to #700, if the track is over 15 banking. The front springs seem soft, but every car is different. If the car is balanced well, you could raise the air pressure in the RR, try 3 or 4 pounds and see what it does. Like I said if your overall balance is good, this will make quite a change. If 4 pounds of air doesn't do much, your probably off somewhere else, likely spring rates or a bind somewhere. Are you running coils or leafs?

Were runnin coilover springs all around. I don't have a #700 spring but I have a #750. Would that help it turn more? The track i'm racing at is a 1/5 mile meduim banked track, which is usually dry slick by the end of the night.

You may get some argument on here, but I did this last year and it helped a great deal. I would try the 750, just be sure that you have the other one in case it doesn't work, like I said almost all cars are different. No matter what you do, don't be afraid to try the pressure increase in the RR. If the pressure increase helps and doesn't slow your lap times down, do as cd2 suggested with stagger.

I just always like to try and get the "sliding" end of the car to hook up before I "un-hook" the end that has the most traction.
