Not lowered yet but want to ensure that there is no rubbing issues before committing to coils. let me know what you think
Fronts will hit the strut without a spacer. I was running an effective offset of 25 with 9.5 wheels to clear.

Head to tirerack or the tire manufacturer website for accurate specs. Tire diameter and tread width are important factors to compare.

here's the google sheet. Should be able to filter the data to find what you need. this list will expand once people enter more data in this thread.
Add me as an editor. I like the sheet. You gotta post your specs in the thread too and not just on the spreadsheet.
BBS fi-r 9.5x19 et 22 and 10.5x19 et35 with stock tires. I'm on kw v3 so rubbing is dependent on height. I've had to raise it up a bit because it would rub the front wheel wells on hard breaking and turn in at the track, but I've since fixed that.
How is it that with stock tires and 0.5 inch wider rims the tire side walls sit so perfectly flush with the rim?!!

I found a wheel setup on an M3 for sale.
I am wondering if they will fit on an F87 M2 with stock suspension.

20x9.5 ET18 265/30R20
20x11 ET37 295/30R20

Any idea? 🙏
Suggestions are appreciated

Just thought I would state for the record that what I had read over and over on this forum was absolutely true.

- M Performance suspension dropped to 595 front / 600 rear
- Stock 245/265 tires on stock sized wheels
- 12mm front / 10mm rear spacers


NO RUBBING and pretty well flush fitment.

Beyond that, the ride, like most everyone said, is actually better than stock.

Absolutely fantastic combination IMO, and would have loved if the car had come this way from the factory.

NOTE: Every single picture I take of this car shows the fitment differently. It has to do with where the sun is, and the shadow (from the front fender and rear quarter) on the tire.

The standard flush fitment on the M2 front is 19 x 9 +17. Your front wheel would be 5.3mm outside of that, and your tire is wider, so I think you'll poke at stock height, and rub on big dips.

The story is the same in the rear, you're 5.7mm outboard of standard flush, and the tire is much wider than stock, so my feelings are the same there.

Maybe someone with first hand experience with these sizes can give you better advice.

NOTE: You might very well get away with this wheel/tire combo if you drop the car, and also camber it to suit the fitment, OR if you leave it stock height and don't mind a bit of poke and don't drive it hard with passengers.

I have seen the below being recommended for M2.

I wonder how much difference will that difference in offset make

20 x 9 +17 is flush for the front
20 x 10 +30 is flush for the rear

The specs you're saying are recommended are 3.3mm outboard of flush on the front, which isn't too bad. Camber can fix that easily.

The rear recommended specs are .3mm less than flush, so in other words, spot on.

Let me explain it better this way.

These specs are flush for the front, 19's or 20's:
19 x 9 +17
19 x 9.5 +23
19 x 10 +30

These specs are flush for the rear, 19's or 20's:
19 x 10 +30
19 x 10.5 +36
19 x 11 +43

The only difference is the tires. When you go to 20's, because of the way they fit, you can usually fit a bit wider tire. So if a 285 is an easy fit on a 19, a 295 is usually an easy fit on a 20. And this is simply down to the smaller sidewall and how it's stretched over the wheel.

Hello,

Im thinking of doing the following setup and want some help to make sure the front and rear offsets match to achieve a flushed look.

BC forged HCA383S 2 piece wheel

19x9.5 et22 with 265/30/19 front
19x11 et40 with 295/30/19 rear

Im going to lower the car on Ohlins R&T coilovers.

Your feedback is highly appreciated guys, thank you !

That is basically a perfect spec for both.

9.5 +22 should clear almost any suspension at any height with a 265/30

The rear will be close but will also work.

You will need to add a little camber front and rear. I doubt more than -2 is needed for either.
