When looking at one of the OEM wheel configurations on the M2 as a baseline, 19x9" ET29 front & 19x10" ET40 rear, we can compare a couple different square options: APEX 18x9.5" ET22 Up front, our 18x9.5" ET22 will have just about the same inner strut clearance (1mm more), and the outside edge of the wheel will EXTEND an extra 13mm towards the front fenders. In the rear, our 18x9.5" ET22 will have 24mm MORE clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 12mm towards the rear fenders. For a street car looking for a flush fitment with street tires, this is probably a good way to go with 265/35-18 street tires. The lower offset would lend itself to a flush fitment without the need for spacers, Depending on ride height and tire brand, a small amount of neg camber may be necessary. For a track car running r-compounds, it may be better to run our 18x9.5" ET35 wheel for more clearance to the fenders front and rear, allowing more space for r-compounds that tend to run wider then the avg. street tire. This would also allow more room should the driver want to bump up to 275's. APEX 18x9.5" ET35 Up front, our 18x9.5" ET35 will have 12mm LESS clearance on the strut side, and the outside edge of the wheel will be at the same point. In the rear, our 18x9.5" ET35 will have 11mm MORE clearance on the strut side, and the outside edge of the wheel will RETRACT 1mm. With 12mm less clearance to the front struts, this fitment would likely need small spacers up front for proper strut clearance. APEX 18x10" ET33 - Square Up front, our 18x10" ET33 will have 17mm LESS clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 9mm towards the front fenders In the rear, our 18x10" ET33 will have 7mm MORE clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 7mm towards the rear fenders With 17mm less clearance to the front struts, this fitment would definitely need small spacers up front for proper strut clearance. Negative camber would also be a must for the front of the car. - Ryan

An 18x10.5" ET32 in comparison to the stock 10" ET40 wheel would have 2mm MORE clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 14mm An 18x10.5" ET40 in comparison to the stock 10" ET40 wheel would have 6mm LESS clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 6mm. - Ryan

That said, we're now running 18x10 et23 275/35/18 up front with -2.5* so the 9.5 et22 with 265/35 should be fine even with a little less camber. |

Tried to fit 18x10 +25 with 285 hoosiers and I don't think it will work. The offset is too low and the wheel is a bit too wide. The EC7's clear the calipers though barely.
Edit: Not sure why the pics are sideways when uploaded |

I'm likely going to go with a narrower wheel like a 9.5 and a higher offset. |

In my experience all BMW's do well with a square set up. |

Hi guys!
I haven't got an M2 yet, i'm planning to buy it next year, but i'm preparing. I would like to use 18" wheels (which i currently have) for DD use, but i'm not sure they can be fitted to the M2 since it has so big brakes. I know the brake disc diameter is 380 mm but how much further the caliper extends? Can somebody measure the radius of the caliper's outer edge from the center? It would be a useful info for many people what is the smallest wheel inner diameter we can use. Thanks! |

Anyone know if 18X9" ET31 /18X10" ET33 APEX EC-7 WHEELS with 265/35/18 and 275/35/18 would fit stock suspension?
I want to stay in B stock/street autocross class so the above fitments and widths would have to be used. |
