9 second stick cars with stock decarbons? let me guess they had stock 10 bolts in them to hahahahah

Most also say lid and catback cars don't do 12's does that make it true?

The 9" rear of that design sucks. Mosers have issue's to, same housings. You have to have control of the instant center and move that around.

Shocks and springs help very little. My car had 90k+ stock shocks/springs and never hopped.

Pinion angle should be pretty close to 0 to -2. BUT,depends on how you measure pinion angle too.

yeah thats what im trying to track down. i still get a slightttttt drive shaft vibration at highway speeds around 65-85. just sucks i have no real time to fuck with it lately and summers almost over!!!!!!

I've heard people have cured some minor wheel hop before by putting in better shocks, but these aren't serious drag racers. I'd go with what Slowhawk recommends in any case.

i know this is kinda an old thread but pizza do u have drag bags already?

i have eibach drag launch springs that have the bag but its not installed at the moment.

set my pinion at -2.5, lca's in middle hole and put my sway bar back in wheel hop is gone just burns the tires thru 1st and 2nd.

Yeah my car doesn't wheel hop at all. And don't listen to Jon. I've got bilstiens and a eibach pro kiit on my ss along with lca brackets and phb, boxed lcas, etc, etc. I think it could be a pinion angle. We did mine with the car loaded on jackstands and went from there. I think its at like -1

So your saying lowering springs and bilstiens are a good drag setup lol ok
