Here is a vid of how the Comp 3-ways acted on my clutch car last year. Notice the compressed sidewall and then it bounces back up. This was with 26" ET Streets and leaving at 6k, but if you're tires are closer to the fender, you can see how they'd bounce up and hit the lip. I'd bet money this is what's happening to yours. Give Brian a call at Madman. He'll be happy to get you setup with a shock you need and explain why the Comp's aren't going to work for your 6sp car.

.02 into the vid and it appears you have way too low of tire pressure as the rim just about touched the pavement

The CE we use on my dads auto car and work well, but surely a SA or DA QA1 or Strange would work much better.

I would put the stock springs back in there and tape up the wheel well and give it a try. if you still notice the car squating then I would set the shocks on the stiffest setting and try again.

They were brand new when I put them on, I guess I could be wrong but remember being like WTF how do I set these when I first got them because they dont say anything. I got to make 2 passes at the track after I got them and looked like a fish out of water going down the track. I changed it a bit but the track closed and I havent been back since but felt better on the street.

check the shocks as you now have more info

raise the car a little if you need clearance ( as you stated with stock springs )

recheck suspension adjustments after new ride height is set

stiffen up rear shocks ( as you noted )

Tire pressure didn't make any difference. I tried as high as 22 and as low as 14 before the tire started to slip on the wheel. The 60' seemed to like 15 the best. Part of the problem was the short sidewalls on the 26" tires. I run 28" (s) now with Afco d/a's.

Ac here is some info. When the car has the first hit (you letting the clutch out) you want the tire to take the shock. Not the shock. Thats why with a well setup car off the line you will see the tire and rear and the body push away alittle bit. I know your m6 But watch this vid Of chris right at 2.15 sec to 2.16 you can see what i am talking about.http://www.youtube.com/watch?v=iYq4bOPDoaU

But alot comes into play. How the car sit's TQ arm angle LCA angle's and so on. Best way to get the car to hook Is find the live center of the car. Soon i will be doing this to my car. And scaling it.

And Steve Madman Whats the best way to go about and setting up the live center of a m6 Car??? I am new to this but I am learning.

Wow did you end up fixing it? The comps worked fine when I had a 27" tire the front was just jacked. If my car squats an inch will hit so I think raising it and setting the shocks to stiff will cure it. It didnt really feel like it unloaded like yours but again I cant be sure since I was driving. Never showed signs of that before the 28"
this was stock shocks and was great with 27"s They werent even close to bottoming out

too much antisquat.
double adjustable shock would help that issue also though(i think DA's for the rear a much more benifical that for the front)
mine doesnt really squat, but doesnt lift either. just rotates over the axle

I'm not stating this was related to shocks, but just an observation. I'm sure your setup now works well.
