Thanks for advice. I'm going to flip the tires and ask the shop to put as much negative camber up to -3.5 front and -3 rear. I'm not sure if my camber plates can get to -3.5 maybe I can get -3.

Aside from the tire wear how is the handling balance?

I have some basic spc lower control arms.

Not great, you'll have to compromise somewhere or at only 2-3 events per year maybe adjusting front between Street/track specs could pan out.

I only did 4 events last year, and ran my street tires on day one of each event. With 4 track days on my street tires (245/40-17 Conti ECS) and ~5000 street miles, all at -3.5 front camber, I have even wear across the treads. I did rotate between each track event.

Be aware not all tires are able to rotate in a front to back opposite sides

I got about 15k miles out of my firestones but they were probably due to be replaced at 10k miles and were sketchy as fuck at the end, alignment varied throughout.

Big change if you're used to getting 60k miles out of your daily tires... It's all perspective.

Hopefully you're not staggered, so swapping front/rear should be no problem.

As for left/right, directional tires *can* be driven in the "wrong" direction without issue. I've done it many times. Tests have shown that running directional tires backwards pretty much doesn't make any difference even in standing water. From what I've read a lot of times the directional pattern is more about noise than actual water-handling or hydroplaning resistance.

That said, for *street* usage rotating front/back is fine. However for multiple track days at the same track, you'll want to do the normal rwd tire rotation pattern (or any pattern really that ensures each tire winds up at each corner of the car on a regular basis).
