Just wondering if 18x8 with 225/40/18 at the front with an et40 and 18x9 with 255/35/18 et45 at the rear...Will they fit an E30 M3 if I used spacers? The car is lowered about an inch

you would need 20 and 25mm spacers, the rear will all but certainly rub no matter what.

That staggared setup will understeer really really bad.


I run 18x8.5 wheels and 245/35 tires all around. No rubbing.

Thats TOO wide for the rear.... i'd say go 235's all the way around!

NEVERMIND, just realized the rims are staggered!

This will sound crazy, but I'm serious.

The fronts will mount without spacers, as bare wheels. If the tires have huge curb protectors, then you will need a small (5mm) spacer.

The rears, I'm not as sure about. I wouldn't be shocked if they mounted without spacers also.

Yes, it should fit with 15-20mm spacers all around. You will probably have to roll the fender lips too. Also the tire sizes are a little larger than optimal.

I've test fitted 17x8.5 ET40 Kosei's on a slightly lowered M3.

They took 20mm of spacer all around to clear struts and be pushed out enough to look good.

18x8 with a 225 will rub the strut, if not still it will under corner load.

The rears will not mount without spacers.

FYI my 18x8.5 with 245/35 in back rubbed the inside tub, I had to make a couple choice whacks with a deadblow to make clearance. You cant tell after the reundercoat, but it only happened under corner load. The wheels are as close as is humanly possible to the outside fender lip.

No way in hell 18x9 ET45 will mount without spacers, even with a naked wheel.

Oh, also.. again.. Do NOT run a staggered setup. Run the same size wheel and tire all around. Unless you have massive amounts of power you don't need it. e30's plow with extreme understeer with a setup like that.

For a 17x8.5" wheel to clear the strut, you would need ET29 or lower. So the 20mm spacers were actually a lot more than necessary.

18x8 ET40 will honestly make it. For reference, a 17x8 ET35 wheel will work, and the front strut angle provides just over 6mm more space per inch upwards. So the wheel in question should have 1mm more space than the 17 which I know works,

You're most likely right about the back, like I said I'm not sure at all.
