Rear street/strip shocks
I can get 1.6x 60 times if i roll into it off the line, but if i nail it off the line the back end squats and i blow the tires. Current shocks are not so new kyb's. Would i be wasting my money with a pair of bilstiens, or do i need to get some adjustable shocks?
Whatever i get they need to be able to handle some street miles as this car is 98% street and handles good and i dont want to mess that up. Car has hotchkis leafs. MT drag radials. No traction bars. No wheel hop. I just want to reduce the squat with some durable shocks if possible

Just not a lot of front end travel there.

I don't think any shock will keep it from squatting. That's what traction bars do!

Ok here's a clean pass so u can see the front end come up some.
https://youtu.be/2_o3_sufXfA Remember this is a street car and i dont want to loosen the front if i dont have to and i would rather not install traction bars. My goal is to have more consistent hookup and not compromise street handling. Im hoping an affordable pair of rear shocks can do this. I know its going to squat but cant it be minimized some with some stiffer rear shocks? I don't mind a firm ride.

If you can find a shock that is adjustable and can be like a 90/10 shock would help probably.
Need to have it easy to go up but stiff to go down. Might try putting some clamps on the front part of the leaf springs. Changing the front/rear weight ratio would help also.

YOU Have very little front end travel, going to need more then that to really make those radials work, make sure everything is loose in back no over tightened bolts etc
all that **** will make the suspension bind and not work right.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
