Maybe try softening up the rear shocks a little use softer clutch shoes and lighter springs, I'm gonna get drunk now.

I'm not personally familiar with the setup options on the RC8... IF this set of adjustments is an option, you might try this:

1) make the rear camber links as long as possible- in other words, if there are options to go inside or outside holes on the rear uprights/hubs, put them outside... and on the inside holes on the shock tower.

2) If you can change the roll center (by moving the inner end up the rear camber link up or down where it mounts to the shock tower) raise it.

3) If there are adjustments for position of the rear arms (further forward or further back) put them forward to put more weight on the rear wheels.

4) Increase the toe-in in the rear.

Don't do those things all at once, try one at a time... otherwise you may make the rear TOO planted, which makes the car tend to push. It is all about a balanced approach.

+1 and all those adjustments are available

thanks for the helpful info. I found part of the problem this weekend.I found most of my assend looseness was when I was off the power in the curves or on the power in the ripple bumps,so I believe a lot of the problem is to stiff rear springs
