Allright I have a quick question....

I have some Roush rear springs installed on my car. They lower the rear end to an almost level position. The instructions said approximate 1" lower. I want to install a PSI Performance 4" aluminum one-piece driveshaft on my car that a buddy of mine has installed on his car currently. He is going to the H&R Supersport springs, and he knows he will not be able to use the driveshaft while going that low. The question is... will I still be able to use the aluminum driveshaftwith my Roush springs if I were to buy it from him?

 

Yea you can use it but you will need either adjustable Lower control arms and/or Upper control arm. You need these because you will need to adjust the pinion angle which will be off from lowering + 1 peice ds

 

the 1" drop is fine for a 4"ds unless you drive with 4 200 pound people in your car. adjusting the pinion angle ensures you are getting the most out of your power but is not necessary right away.

 

I have lower springs and a 4" DS with no clearance problems.

 

Thanks for the info...
