I would start with a set of QA1s first. Is the car stock height or os is lowered?? What angle are your control arms in rear??( are they running up hill from the rear end to the body)

it has a stock height, as for the angle, I am not sure . A shop adjusted my pinion angle. and I have an adjustable control arm to.

as for shocks , do i need a set of 4? for front and rear? shall I go with the spring shock package? what spring rate is recommanded?

Thanks.

Get the single adjustables. If you want doubles DO NOT go with QA1. Either AFCO or Strange. The stock rear springs will work in the rear.

stock springs and shocks too.
I come from the school that says solve/verify (launch) technique issues before spending money on parts.

If other drivers with similar set-ups are able to get 1.7x-1.8x from MT Radials, why can't prostock_bigblock?

Is the hypothesis that the his rear shocks are worn out? Other drivers on stock shocks seem to run faster 60'. Is it the shocks? Or is it a technique issue?

prostock_bigblock did not answer the question is his car bogging or spinning. On a Corvette, to make properly heated MT Radials to spin took 2000 higher launch rpm than on stock tires; for me that meant 4600-5200. It is very difficult to imagine that prostock_bigblock is not seriously bogging his engine on a launch of just 2600.

Heres a video I made. You can see the tires work great. Get that suspension done. It was one of the best things I did to my car.
Oh BTW, I am a big fan of the BMR extreme sway bar and QA1's. You will be able to see the car used to twist bad. After we did all the suspension stuff she went up straight in the air the first night out. Thats the last shot in the video..
