2nd gen rear camber - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

This probably a noob question, but...since the rear camber is not adjustable with the stock LCAs, why does the camber on both left/right sides end up at different angles after installing coil overs?

I understand it adds negative camber naturally from lowering, but assuming both sides are equal from the factory shouldn't both sides have negative camber increased by the same amount?

And if they differ due to a variation of the install, wouldn't that make them slightly adjustable?

Current rear camber: -3.5, -2.7

Most cars are not even from the factory.

In a traditional sense, you are correct. You can't "adjust" rear camber the way the car is. There is no eccentric bolt or elongation that can be done with the stock arms.

However once you introduce coilovers, you have added a dimension of adjustability that wasn't available when the car was stock: ride height.

So yes: if you are okay with having potentially different ride heights between the two rear corners, you could get close-to-even camber left-to-right. The difference in corner height needed to do this can be reduced if you decide to get the car corner balanced as well

As mentioned, it's not gonna be "even" from the factory. FWIW I'm at -2.48 left and -2.89 right rear camber (lowered ~32mm).

I don't think i'd be tempted to even out rear camber by running different left/right ride heights though!

You could loosen up all rear linkage bolts and physically try to force a smidge less camber on the high camber side, and more camber on the low-camber side. Might close the gap a few tenths...
