is the alignment on the FRS/BRZ adjustable?

I owned an Evo and S2000 and these cars offered pretty decent adjustability, unless you slammed them you could adjust it back to neutral or set the camber & toe to desired settings without purchasing aftermarket kits.

Does anyone know if the OE suspension on these cars offers some adjustability too?

There is definitely room for camber/caster plates up front. They appear to have a concentric bolt adjustment for camber up front which allows for a little variation. from what I've seen for parts diags so far, I can't tell if there is caster adjustment or not. Toe is always adjustable.

No eccentric bolt.

I'm certain that there is camber adjustment in the front. Even a base Impreza from the '90s has a concentric bolt in the top of the steering knuckle. Never seen a mac/strut set-up that didn't. How else would they achieve camber specs that compensate for the road crown ?

The pre-production cars do now have front concentric bolts. We'll see what the production cars have.

Rear camber is adjusable and all four wheels can be adjusted for toe.

In my limited experience (E28/240SX/240Z) McPherson struts generally don't have camber adjustability.

As for "road crown", the only people who ever mention that regarding alignment is the alignment shop when you complain that the car pulls after their work. If it pulls to the right you get "oh, that's due to the road crown". If it pulls to the left "Oh, they set them up to do that from the factory to compensate for the road crown"!

Nobody *really* sets camber for "road crown". That would mean POSITIVE camber :P

Most Subarus do generally have at least front camber adjustability built in and I'm surprised the BRZ's we have seen so far have not. Maybe they'll add it for the production models. Either way, a quality front camber bolt is a cheap OEM part to add and it already exists. And of course we'll have camber plates ready to go if you want lots of camber.

Not sure where the "there is no eccentric bolt" and "macstrut cars don't have camber adjustment" stuff is coming from because neither is true. It had been confirmed a while ago that there would be eccentric bolts in the front. WRXs and STIs have been using the macstrut for ever and have eccentric bolts from the factory for camber adjustment.
What in the this picture is evidence of no eccentric bolt? Because I sure can't see a lobe or lack of lobe on either bolt.


This car definitely has an eccentric bolt in the upper knuckle-to-strut mount that will allow about a degree of swing. Current WRXs are able to get about -2.3 degrees of camber adjustment with larger eccentric bolts.

The bolt on the right is a stock Subaru bolt:

FTR, I said "generally"...

I'm officially encouraged.

Don't see how 2mm swing would amount to 1 degree camber change, unless the top of the strut is fixed only 4.6" above the eccentric bolt?

Anyway, sounds good, we won't be stuck at 0 - 0.5 deg

Umm, you'll have to take my word for it...but the upper bolt is not eccentric for the BRZ. It usually is on subarus, but not this time. Maybe it'll change for the production cars, but it is not adjustable for the BRZ. Trust me.

Interesting...so how is the camber adjustment going to happen for stock classers?
