Rear end Grip ? Help plaese :)

[andys]

I've being running the X11 at Bury indoors with mini pins all round. (sports centre kind of carpet / low-ish grip surface)
Problem i have is rear end grip, or lack of it. Can someone please point me in the right direction.

I'm running the kit / kev lee setup (sort of as I have kit pistons, so heavier oils) Everything else is standard. I'm running 3 degrees of toe in at the rear, 1 degree camber all round.

The car could be ace, but when pushed, especially exiting a corner, the rear end breaks free and becomes the front end ! I've tried softer rear springs and different shock mount positions to soften the rear even more, also i've raised the rear, but it still breaks away.

It's starting to do my head in as the car is really quick and so nearly there, I just can't push it unless I want to powerslide out of every corner os feather the throttle whilst everyone goes past me !! Help.

Cheers. Andy.
