Anyone have experience with installing a camber and toe arm in the Rear? My main concern is how you guys went about loosening the bolts/screw on the end closest to the vehicle. Anyone have any advice

 

Have all the right tools (ratchet sockets wrench mallet) ready and some time and patience. It's a tight squeeze and you will do very small turns of the wrench for the inner bolt and it will take a very long time to finally get it out
be warned of knuckle busters

 

Lift both rear wheel tire while working on the rear so the sway bar don't fight with you. It took me about 15 minutes on each side to install SPC rear camber kit with my bagged rwd is200t. I recommend to use XL Flex GearBox Ratcheting I believe its either 17 or 19 mm.

 

 

Good find!

I'll eventually get one as well on my stock IS350 since the rear is set at -1.7 camber.
