Best to measure from center of wheel hub to edge of fender.

More negative camber up front would be ideal for the track. And slightly less in the rear, but it would be good to know your spring rates.

Thanks! It's Tein Street Flex standard spring rate.
I am debating lowering the rear a bit to lessen the camber and push the fronts a bit more to 3.0 at the track.

That's very soft, especially with a 35mm drop.

Lowering the rear ride height? That will increase rear negative camber.

You can also change handling balance a little with rake if you like.

Right now I'm running -3.5 degrees of camber up front with RCE Tarmac springs and koni yellows. And about -2.1 degrees of camber in the rear. Stock sway bars ect. In autocross this setup is great. Just grips everywhere. However I will say it lost its fun factor for daily driving. Its so grippy in the front and the rear now its hard to slide the car around like it did stock. I have to drive it really stupid on the street to slide it at all and thats not something I'm willing to do. I miss sliding it around at 10 or 15mph like it was nothing.

Yeah sorry, I meant raising it a bit on the rear.
Ride height is about 24.5" floor to top on fender front and 25" on back.

This is the specs I used to adjust the coils before installation.

Do you remember what the ride height was before your coil installation? I've been looking for this info everywhere and cant find it.

Just installed some Koni's on the car with the stock springs. I got ~14" front and ~14.5" at the rear. There still settling

that's measured from where to where? I'm guessing the hub to top of wheel arch?

[FastWhite]

Correct, center of wheel hub to the wheel arch.

Before installing my coil-overs, stock height was 14.5 inches from the center of the hub to the center of the fenders F&R. BRZ limited, mounted on 225/45 17.

Is that a bad thing?
