B4 Rear end grip

[Adam31]

HELP!!

I'm new to 2 wheel drive and raced my B4 @ Chadderton this weekend i need some help with setting it up, i've tried the set up sheets i found on here but still have the same problem, this being my car turns inn then the rear end just breaks away. I probably spent the whole day racing at half throttle :-( Any advice would be greatly received.

Thanks Adam
