Hello everyone!
I would like to buy a set of wheels to use on the track for my E92 M3 and I don't want to use spacers! I was thinking about 18x9.5 ET22 at the front and at the rear with 265/40/18 tires. What do you think...could it be a good idea for car performance? Mount the 2-way KW Clubsport, without spacers say that the wheels will touch the front suspension?
Thank you and sorry for my grammar

18x9.5" ET22 will absolutely work as a rotatable square fitment, and the optimal tire size would be 275/35-18. There are a ton of good extreme summer and r-compound tires available in that size, and they are closer to the correct rolling diameter then 265/35-18 (265/40-18 is a bit too tall for the front of the car and could cause rubbing/damage under suspension compression).

From an aesthetics standpoint, the 18x9.5" ET22 wheel will actually look almost identical to the very popular 18x10" ET25 in terms with how they sit in relation to the front and rear fenders (flushness). They are within 3mm.

The 18x9.5" ET22 will also give you plenty of inner strut clearance for the KW suspension, which are notorious for requiring spacers up front with 10" wheels or wider due to the fact that they take up more room than other suspension designs.

Thanks a lot for the answer. I proposed measure 265/40/18 because it is the one written in the vehicle registration document and on the advice of a tire dealer, but if it is better 275/35/18 I will use this measurement!
I was just thinking of buying Apex wheels. I have seen that ARC8 weigh less, but EC7s have more room for BBK. What do you advise?
Thank you,
Matteo

Use the 275/35 tires. They won't be road legal for the car inspections but you can switch to your other tires for that

Do you have an idea of which BBK do you plan to install?

The ARC-8 design in E9X M3 specifications will actually clear a wide variety of brakes including the StopTech 6 pot 380mm, but there are some limitations due to the barrel construction like a Brembo 6pot 380mm for example. The ARC-8 was our first wheel design, and still the most popular to date. Since then, the barrels on all three of our newer wheel designs (EC-7, SM-10 & FL-5) were specifically developed to clear the largest brakes on the market like the popular Brembo 6 pot 380mm BBK. All four of our wheel designs come in the 18x9.5" ET22 specifications, so you have some options depending on which design you enjoy most.

No, I don't have a precise idea yet but I would like to take the wheel with more space. Where can I buy them at a good price with shipping in Italy?
Thank you

if you are buying new you should try to get the 10" wheels, maybe 10.5, not 9.5

These are heavy cars and wider wheels provide more support

Solid advice, although my understanding is that OP did not want to run spacers. Unless he is open to modifying his KW Clubsport spring configuration to raise the lower spring perch, he won't be able to fit the 18x10" ET25 or 18x10.5" ET22.

Is there any problems to run 18x9.5 with a 275 vs a 18x10 ?

No problems, I run 275 on a 9.5 wheel.

Most 275 tires should be just fine on a 9.5" wheel. If the tire model you are considering is known to run wide, you might be better served with a 10" wide wheel.
