i was wondering if the bmw rims will just bolt on to chevrolets. i have a set of bbs rims off of a 1997 bmw 318i, from everything i've been able to track online it seems like they might. i would, no doubt, need a set of spacers to balance the offset., but i can't figure out if they'll just "bolt on" once i gamble on the spacers or loose a wheel flying down the freeway. here are the details........offset on the bmw wheels is 40mm Camaro is 0mm
Chev Camaro (82-92)
WHEEL SIZE -- BOLT PATTERN -- OFF SET -- HUB BORE
17 X 8 -- 5 X 120.65 -- ET 0 -- 70.3
BMW=
17 X 8 -- 5 X 120 -- ET 40 -- 72.56
there is about one half of a millimeter diffence between the beamers and the mighty camaro's bolt pattern...... HELP! ha ha ha

From that info, it doesn't look like it to me. Also the holes that the studs go through may be different. I don't know the size of the bolt that BMW uses, but they don't use a stud and lug like our cars have, they use bolts, may be a smaller diameter...
Interesting idea though, some of those 18" M3 and M5 wheels look killer!!!
A search will reveal that there are a couple members here who are running or have run BMW rims on their cars.
If you decide to run BMW rims, you will need hubcentric rings to keep the wheel properly centered on the car.
Also, look for wheels with the same backspacing as youir car. The BMW wheel you are currently looking at has an offset of 40mm (ET40), and the camaro uses an offset of zero mm (ET0). If you went with the 40mm offset rims, you will also need to run adapters.
Personally, if I were you, I would look for wheels the you like in the correct bolt pattern.
Here are the results of a search for the term "BMW Rims".
I read an article in one of the Hot Rod magazines with a 91 camaro with BBS rims. Looked killer, but it didn't go into detail about how they put them on there, but it can be done. I was seriously contemplating putting a set on my car after seeing the article. That was before I got a good deal on a set of 17" WS6 Rims.
These rims are 18x10 right off my BMW 740. As I mention before you should use adapters (spacers) I have 1 1/2 inch mounted. The both pattern is the same. with out the adapters you may have a problem with the large center hold on the camaro as MR.Dude_1 mention:
BMWs center the wheel using the bolt holes.
Chevys center the wheel using the big round center hole.
Chevys center the wheel using the big round center hole.
Really i don't believe it. On my stock rims the hole is way bigger then the other part on the spindle or axle. There is no way it is used for alignment.

The acorn lug nut center the rims on the lugs.
well it is.
that center hole is all that centers the rim.
just look at it more carefully next time you take the wheel off... remember that the fronts have a taper, but its the innermost flat part its actually using.
So what is needed to run the BMW wheels and where can they be bought? How are you centering the wheels? Sorry, I can get a steal on a set of 750il motorsport wheels that would look killer and just need to know what to buy to run them.
To my understanding it is just the opposite, the chevy wheel has to be dremeled to fit on a BMW, but I could be wrong.
Maybe I misunderstood the posts.....
Research shows......
Our hub to be 70.3mm...
BMW hub to be 72.5mm...
And I found slip-on hub centric adapter rings, to fit 72.62mm to 70.30mm for $21 on eBay.
Sounds like for $21, BMW wheels will slip right on. I doubt the 1.2mm will make a flipping bit of difference. Besides, the cone lug nuts with center the wheels anyways, meaning the rings really wouldn't even be necessary.
the hubcentric wheel is stronger because the 70.3mm hub wont deflect if you hit something where the studs will move . It's also possible using the wheels as lug centric that if the studs aren't perfectly aligned the wheel wont be perfectly aligned with the center . Most aftermarket wheels are lug centric , most factory wheels are hub centric .
well it is.
that center hole is all that centers the rim.

NO NO NO NO NO ARE CARS ARE LUG CENTRIC, THE HOLE IN THE CENTER OF THE WHEELS DOESN'T TOUCH ANYTHING ONCE THE WHEELS ARE TIGHT. IF THE HUBS TOUCHED THE CENTER OF THE WHEEL THEY WOULD BE PRESSED ON SO TIGHT ONCE YOU INSTALLED THE WHEEL THAT IT WOULD NEVER COME OFF.... I MEASURED THE BORES OF MY SETS OF 15x7 FACTORY WHEELS AND MY 92 16x8 WHEELS, THE BORES DIFFER SO MUCH ITS NOT EVEN FUNNY I THINK IT WAS LIKE .075" FROM THE SMALLEST TO BIGEST BORES, SO NO ARE WHEELS AREN'T HUBCENTRIC, WHY DO YOU THINK THE WHEEL HAVE A TAPERED HOLES FOR THE LUGNUTS.... IT'S SO THE WHEEL CAN CENTER IT'S SELF ON THE LUGNUTS

you have to take that in account when doing it.
All BMW wheels are hubcentric, they even have different hubcentric rings for different models available for original BMW wheels.

The .65mm difference in bolt pattern is is about .026" or .013 per stud. This is going to put some bending into your wheel studs when you tighten them down so you may start breaking studs. On a slow day I ran some bending calcs and came up with 40ksi of bending stress on the stud (worse case scenario), not good at all when you should be torquing the studs down to 60-70% of their yield strength. A half inch spacer cut the stress by a quarter by spreading the bending over a long distance and cut the stresses down considerably.
I would run BMW wheels, but only with a hubcentric spacer or wheel adapter with the correct bolt pattern.
