I'd get also camberbolts though in addition to camplates, as just camberbolts or just camplates might be insufficient for optimum track camber of -3 and up. +rear LCAs to up camber in rear too.

Subaru makes their lug nuts out of putty; several owners have reported issues with stripped lug nuts and broken studs; mostly only on the front axle. I always hand-thread lug nuts before using the impact wrench on them and then torque and double-torque to spec after any tire changes since I work in a large retail tire shop; it's just second nature. My guess is because I tried removing the wheels shortly after coming off the track, the heat from the brakes may have expanded the metal causing issues.


I have camber bolts and rear LCA's currently; unfortunately I can only get about -1 degree in the front with just bolts so plates up front need to come next.
