Woooo, first post here! Long time lurker... Stoked to add to this thread. This is my outgoing set up. Will post my new set up later this season.

Wheels: Kosei K1 - super cheap, super light!!!

Front: 17 x 8.5 +40
Spacer: none

Rear: 17 x 8.5 +40
Spacer: none

Tires: Falken FK510
Front: 225/45R17
Rear: 225/45R17

Suspension/Fender Mods/Camber:

Bilstein B12 ProKit
No fender mods
-3.0 Front camber (M3 LCAs, Turner camber plates)
-1.5 Rear camber

Notes:
This a pretty tame set up. Run it hard at the track with no rubbing issues. I will make a new post when I move to RT660s (likely a 235/45R17).

Also note, the wheels have no issues clearing 135i 6 piston front brake calipers.

For comparison, the ‘existing’ is the biggest factory setup I found listed, new is your setup: https://www.willtheyfit.com/index.ph...h=8&offset2=45

My 17x8.5 ET40 245/40 do not rub on my lowered car (ever). My 17x9 ET41 255/40 rub in the rear with straight line driving (expansion joint impacts), but not while under cornering load. I need a 5mm spacer in front. I’m heavily cambered -3.6/-2.2 AND rolled fenders in the back. New untested setup for me will be 17x9 ET45 255/40 with a bigger front spacer, the rear SHOULD be rub free.

I just got my new set of 17x8.5 et40 with 245/40 and I’m dealing with some rubbing on the rear at the moment. I’m pretty low and currently -1.5* on the rear (maxed) without rolled fenders. How aggressive of a roll did you have to do to get everything to fit? Just asking because our setups are pretty similar. I’d love to avoid rolling fenders but the e9x hub conversion is way too expensive for it to make sense atm
