I think I'm too low..., could be the reason for hopping around Options

[nine14cats]

This weekend at Thunderhill I experienced significant hopping of the car in the rear end. I initially attributed it to lack of an LSD and my inexperience with V710 tire pressures. And this is probably a contributing factor. But another thing I experienced on the old buttometer was that the car felt and sounded liked it was coming to a hard stop (i.e. metal to metal) under suspension compression in the rear. And the sound was coming from the shock towers.

My current thought is that I have the car set too low. I may have been bottoming out the shocks under compression, particularly in Turn 3 where the off camber and application of power without a limited slip plays hell on the car's handling. I'm thinking of raising the car an inch to an inch and a half all the way around. It's currently corner balanced, so if I turn each corner an equal number of turns on the coil overs, it should be relatively close. If I get it to where the hop is reduced or at least the "clunking" goes away, it's probably a good thing for the shocks and for getting the power to the ground.

What do you guys think?

Thanks,
