lowering kit questions.. I'm thinking about lowering my car 2 inches. i think i'll be going with the eibach kit. are new shocks required for this? also how about the torque arm? will this throw off my pinion angle without a different one? Thanks!

Normally I would just say to search because this has been covered many many times, but search is down right now so...

Nothing but the springs are required to lower the car, but the rear alignment may be off (adjustable panhard bar or watts link needed to recenter it) and obviously the front will be needing an alignment. And your ride/handling will be less than ideal (your stock decarbon shocks struggle to damp the stock springs, putting lowering springs on is only going to make things worse.)
If all you care about is the look then have at it, but if you are looking for performance you are headed in the wrong direction by getting poorly engineered springs (sportlines right?) on horrible shocks.

Good question about pinion angle. This is probably obvious for a lot of people. I haven't really cared about pinion angle until recently so I never did any research on it.
Wouldn't the pinion angle remain the same if you lower the car? If the car is lowered, then the axle sits up closer to the chassis. Wouldn't the angle move along with the torque arm and rotate the housing slightly? So basically making the angle pointing a little downward and maintaining the same angle with the pinion and driveshaft?
