Suspension setup help I need some advice on where I should start adjusting?
The car is 3700 lbs race weight and makes 440hp.
It has qa1's with front drag springs set on 5 front and 5 rear.
BMR extreme ta and rear sway bar. The front swaybar is off the car.
Moser 12bolt with 4.10 gears with the harder compound et drags 28x10.5 with tubes @ 16 psi. It now has a spec stage 5 clutch, billet steel fly wheel and steel 3" driveshaft.
It launches like this (from 6k)
then does this (almost stalls)
It is bogging so bad I only get a 1.9 60'
before I changed the clutch and put in the heavier flywheel it would pull a 1.6 60' (bogging slightly) with the same suspension settings and tire psi. The old clutch was a spec 3 with an aluminum flywheel.
I would like to get this right on motor first so I don't put it on the bumper spraying.

With the launch hooking that well, I'd try stiffening the rears to ~ 7, and fronts down to ~3.... other than that, the 28" tire on a 4.10 puts you at about a 3.73-3.90 effective gear ratio(haven't done the math)which ain't helping your cause in a 3700# car. Try leaving just shy of(or on)the limiter if the pad can take it.
I saw you at SpeedWorld. You launched, hooked, brought up the tires, then dropped it back down and then took off. wtf happened?
good looking car. I wanted to see if you wanted to run next round but the f'n rain would not quit..

I think if you sprayed out of the hole it would solve that problem. Either that or you need to switch to a smaller tire cause you don't have enough power for them.
i dont think your bogging problem has anything to do with your suspension settings.
you can always try coming off at 6500-7000 rpm. Just make sure you got a scattershield!
