hi guy

I race in a car park on sunday and the grip is low and some time super low. Any ways while i was getting in some laps wit friend, I realized that my car was spinning alot on one part of the track, going in too a sweeper followed by a left hairpin corner and i was really getting to put the power down while exiting. The car had tons of steering but was lacking rear traction, I was also lossing traction going into a right hand sweeper that takes you to the straight and was spinning out and sometime spinning in a left to right fast corner ......

Need some help guy i use to own a t3 2010 and had loads of steering and rear traction...

hey is the set up i was using on sunday

I was using Martin Hudy low traction setting but with 1.5 front camber and 1 at the rear, also use 2.6 front n yellow springs at the rear and I was using 1mm shim at the front camber link n 2 at the rear with my rear camber link long, droop at the front was y and 5 at the rear and my rear different was set loose. My tires where hpi belted pro slicks.

i never run those tyres so dont know how they run.

you could always try lowering the roll centre on the back. that is what i did to mine and the back doesnt step out at all.

1 degree of rear camber probably isn't enough. Go to 2 and see what happens.
