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.

Hi Andy

I had a similar problem with mine outdoors the other week - I simply backed off the slipper about 1/8th of a turn and the car was instantly much better for it.

Front ARB? (dunno if you have ARB's on the pred...)

I found backing off the throttle high point on my tranny sorts most of my problems with breaking away. the slipper sorted a lot out, but I found it was always slipping when I didn't want it to.

Hi Andy,

If you have weight in the front, try taking that out and moving it to the rear or shifting your cells back. Also make sure the rear diff isn't too loose causing it to diff out on power.

You could also try reducing the front droop to help the front "let go" a bit quicker out the turn. There should be a bit less droop on the front than the rear anyway.

Hi Kev.

No weight in the car at all really, and the lipo cells are saddle packs. I have the front ride height / droop / links etc set up as per your setup. All looks good on the bench !

I guess I could try the stick setup, but the weight difference would be marginal as the speedo and receiver are to the back and I guess they weigh a similar amount the the weight the lipo would create back there.

Maybe need to add some serious lead ? Just seems wierd, even under power as the car is beginning to straighten up, it can break away if I gun it. I had a few 'wavy' runs down the main straight as I tried to get the power down out of the 1st turn !

I did check the rear diff and it wouldn't slip at all, it would break the gears first !

I do have the slipper tight as i've had trouble with it slipping.

Any more ideas on the right rear setup (springs oil etc) as I have the kit pistons in at the moment.

Thanks. Andy.
