I need some help. I have been haveing troubls keeping my rear end of my car in line, when I am going in to the turns my rear end wants to slide out from under me. I do not know how to fix this as it is my first year out. Right know I have a 275 and a 250 rear spring in the car, I also have 205 tires, that are new! I run about 27 pounds of air pressure in them. What can I do to keep the rear in line around the corners?? Any help would be great......Thanks

Your looking at the wrong places on the car. Just cuz your rear is loose dont mean that is the problem. What are you running for a rf spring and what is the weight of the car? Your rf could be nose diving acting as a pivot point and the more momentum you carry the more it will want to hinge around that pivot point and make the car loose you could say. It will want to bring the rear around.

Could be too much front weight or weak springs/shocks in the front.

275 and 250 is a bit stiff in the rear unless the car is over 3500 lbs.

Check the stagger, if the RR tire is significantly larger than the left, it'll feel the same way.

Many many things it could be.

well I think that I have like an 800 in the lf and a 900 in the rf. The car it self weighs 3320 with me in it. Are those to light for the front? DO I need to run like 1000 in the lf and 1100 in the rf? Will this help me out as for as beeing loose? Thanks for the help so far!!

I will look at my notes for the front spring weight for sure, but that should be what they are.....thanks......

Welllll...awright

I agree with 1100 RF and 900 LF. You should probably be running closer to 250 on LR and 225 on RR. If the rear springs are too strong, they will overcome the shocks and promote SUDDEN weight transfer off the rear tires when you lift to enter the turn. Find the stagger that works for the track and stay with it. You shouldn't need to change stagger unless you intend to change your line. On top of running hard in the rear, you're running soft in the front which will allow the RF to squash and let the car lift off the LR and get loose. You didn't mention if this is an early problem or a feature time problem. If the car is okay out but loose in, put more spring split in the rear(stronger LR)and see if it's still driveable out.If you can get Speedway's street stock shocks, leave the car alone and go to a stiffer RF shock, as it will only work on entry, when the suspension is in motion, to slow down chassis roll and keep the LR on the track. Good Luck!!

ok how much front and rear stagger do you have also you might want to try less air pressure i run 205/70/14's and run them as low as 18 that might help. have you scaled the car at all and are you sure your just not driving it in to hard on the bottom seen that before too
