I plan on lowering the rear of my car (08 gt) with the roush rear lowering springs to level the car. I would like to lower the car all the way around but can't due to bumps and angles of some parking lot entrances in my area....(maybe when it's not my DD) so do you have to change pinion angle with just a inch drop? Anybody that has it done, was it worth the money? Been reading threads all night but can't really find a answer on pinion angle. Any help I would greatly apperciate.

 

Pinion angle is not going to be an issue, unless you are very focused on a good launch from a stop. The angle will change, but will not cause any real adverse effects otherwise. I suppose it will get a bit harder wear being less than ideal, but would not concern yourself with it, if you are not a drag racer.

Thanks jazzer! I'm thinking on just holding out till I can lower the hole car at once.

 

"whole" car, silly

iPhone auto correct my bad.....

 

I have seen some hilarious threads from auto-correct, via screenshots.... CLASSIC stuff!

Jazzer's right. Your pinion angle will be fine.

I would recommend doing all four springs at once though. (don't want stiff rear springs and soft front springs)

You should however consider installing an adjustable panhard bar since the axle will be shifted over a bit with the lowering springs.
