Currently running 18x9.5 5x100 255/35 and I'm on Tien coils. And no I don't have my fenders rolled. Any thoughts on what might fix this?

Offser?
Camber?

Just finished installing some new wheels. I noticed no one was running a 345/35r18 rear on an FR-S, so I gave it a go!

Needs some trimming and rubs on lock, but overall, I'm satisfied with the result.

It's been a journey with this car!

Here's my new setup I'm about to try:
KONIG Ultragram 17X10 48ET. (19 lbs.) 275x35r17 Hoosier R7's.
I have the rear fenders trimmed quite a bit. Not rolled or pulled, but the lip almost completely ground off. I have adjustable arms and will want to run -4.5 front camber and -3 rear. I have my fingers crossed. I'm at -3.5/-2.5 with Apex ARC-8 17x9.5+40 (26 lbs.) and Hoosier 245x40r17. I can run lots of spacer on the front and no spacer or 5mm spacer, depending on the 255 sized tire I run.
10-30-2025 UPDATE:
Previously I was running the blue BRZ and now I'm in the Red BRZ. Same 2022 year, but this one has the big spoiler option. I cut the fenders and added flares. I must run 5mm spacers in the front to clear the JRZ's 2.25" OD springs. In the rear I run 12mm spacers.
On a cool 53° track day, a few days ago, at Club Motorsports I was able to improve my personal best by over a second with a 2:43. This is with my untuned, stock internals engine.
