Catch can looks good! I originally had the whiteline rear camber bushings but I sold them off since they looked like a huge pain in the ass to install myself once I looked at how the rear upper control arm was mounted. It's a very tight spot to get those bolts loose. I'm sure the guys at GTE will be able to do it without issue. Just make sure they do it right with the proper tools.
A member here had a shop install them and they hacked up his car since adjusting them is so difficult.

Since I wanted more than + or - .75 degrees of adjustability I went ahead and scored some SPC adjustable rear lower control arms that have more range for adjustment. They were like $275 from ft86speedfactory. If you lower your car more than 22mm you'll probably want to pick up a set to dial out the excess rear camber.
