What is your rear alignment set too?

It's never been adjusted, just verified with my gauge / toe plates, so it's still at the factory setting, just lower - I didn't want to pay for a formal alignment until I stopped messing around with the suspension. But, it's about -2° camber with 1/16" total toe-in (I'll run somewhere between 0 and slightly out on toe once I actually get an alignment).

Was this with rotation? Are you making a lot of power? With rotation last year and the lower camber (~-2.5° front) I actually got pretty even wear on all 4, with basically full use of the tread (as you can see in my picture).

I did one day with 6 sessions (about 100 track miles, or around 45 laps) and the wear I showed happened on session 7, track day 2 after only 7 hot laps and less than 20 minutes on track.

Checking the tires, I really didn’t see a need to rotate yet. I figured I’d do this track day and then rotate. 2 days on front and 2 days on rear would have been an okay result.

I’m not making a lot of power, just a light tune and a bunch of cooling mods.

For those of you with coilovers, what are you running for front camber?

Last year I was maxed at -2.5° on the plates due to OEM lower spring perch clearance issues, however now with coilovers I have a little over -3.5° if I max the plates. Generally I find more to be better on RWD cars, but after 8 sessions at CMP my front tires are roasted on the inside, which is definitely related to more difficulty putting power down at exit (a combination of the camber and the added power).

The picture below is after the 9th session on these tires, which was one session at a TNiA :

This is much faster inside shoulder wear than last year - I was always worried about wearing through the shoulder like this but never did and basically got pretty even wear across the whole tread. I'm planning to bring camber back down to ~-2.75° for Road Atlanta as I feel like I'm losing out on both wear and corner exit performance, but I was curious what others are doing.

I can also do torque limits by gear through Cobb so I may do that as well in 3rd and below.

I have the ball joints on max, about -3.7 with springs and have only been street driving, and lost almost 3/32" in 4k miles of driving on the inside edge. I think the sweet spot on this car is about -2.8 to -3.

Just theorizing, the higher spring rates vs last year could be playing an issue as well, as the front is probably biting more, so you can get on the power earlier. and the lower offset and wider wheels pushes it further away from the centerline, so it adds wheelspin.
