I have an 06 si which i just put 4 brand new tires on. When i took it to get aligned, they told me they think i need a rear camber kit and they were not able to align the car because it will do nothing without that kit. well, the freakin kit is like 400 bucks plus labor and everything. what exactly comes in a rear camber kit? couldnt it just be the spindle? im trying to find it online but to be honest, im not really sure what im lookin for.

Are you lowered? If not, you shouldnt need a rear camber kit.
