Just picked some up used and at -2 deg with camber bolts they won't even go on because they contact the spring perch. They came with 245/40 Forcuem Hena and my suspension is all stock BRZ Performance Package. The tires look like they're pretty wide on the wheel so maybe that's the issue. Previous owner said he had 3 mm of clearance with 0 camber:

He got rid of them because he didn't want to run camber plates but wanted camber. I'm probably going to pull the bolts and go back to 0 camber until I get some coilovers, and get some use out of these all seasons in the meantime. I may try adding a spacer so that I can switch my stock wheels back on for track days and still have camber. I think that's just the price to pay for getting flush fitment with how wide these wheels are, and I'm fine with paying it as I'm eventually getting coilovers anyways.
Other than that though the wheels look great, I just wish I could get them on now!
