Wheel size...width?
Ok...so help me out. I'm trying to figure out what the effect wheel width is on the car.
The stock M coupe wheels are 8.0 in the front and 9.0 in the rear. A lot of the after market wheels are 8.5 front and 9.5 rear or bigger. So what happens with .5 in or more extra width. Are there spacers in there that you can take out, or do you just live with tires hanging past the fenders (eww gross). Enlighten me cuz I'm a retard when it comes to this. I do understand the tire specs and what all the numbers mean, so no need to go there. Thanks |

Ok...let me know if I'm straight or more confused or less..whatever.
So...basically my wheels are fitted to the car with a certain offset (42 f 30 r, from what I've seen). If I change wheels...I'll likely need a new offset that fits said wheel. And it will probably be different from stock, especially if I get different width wheels. So, in order to fit new wheels to the car you get spacers that accept the bolts on the new wheels from your wheel housing. How did I do? |

I've been doing a lot of research on the same subject myself. Someone pointed me to this site, which has everything you cared to know about wheels and tires: http://www.carbibles.com/tyre_bible.html You can also go here for offset information: http://www.1010tires.com/WheelOffsetCalculator.asp Hope this helps you out a bit.

It takes a lot to research to get it right. Basicaly you position the wheel within the wheel well by selecting an offset to suit. Start with the OE specs ...then figure max position of where the outside lip should be (eg flush with fender) On mine I was able to select a wheel with the offset I wanted to bring the wheels flush. I used NO spacers.

Shouldn't any wheel store that you're planning on buying from be able to confirm that they'll fit on your car and whether or not you'll need spacers? I'd rather depend on them 'cause if they're wrong, then they have to fix things.

Same as buying your car; Did you do your own research or just believe the CA?

You should definitely do research, but I wouldn't order anything without making sure that they confirm that the wheels will fit your car. That's all. I don't think buying wheels is anywhere as complex or requires close to as much research as buying a car. Don't give me that guff, inTgr8r!

"Don't give me that guff, inTgr8r!" ... Ouch -
Yeah for sure listen to the wheel guys..... BUT, take it with a grain of salt. Most of them are just looking up a fitment data sheet. Very few have any real experience fitting our cars. I talked to some that had no clue that the M was a different fitment than the 3.0 One thing I did, was look for everyone I could find that had "been there, done that" & got their specs. When I ordered my Volks, the wheel shop was going with far more conservative offsets than what I knew would fit. BUT, I agree... if a shop says "they won't fit, we don't guarantee" ....don't do it. One thing that can really screw things up are manufacturers (eg iForged) that refuse to disclose fitment data. I know one guy that went with iForged, who had a bad fitment issue on an E92. They gave him all kinds of grief - "your using the wrong tires" etc..... The absolute best way to get the right setup is to get trial fitment from a local wheel shop. I've had some seriously wheels on cars to get a trial fitment.

Indeed, offset is critical and it can be difficult to get good information. When I was looking for CSL style wheels for my car Tom at European Auto Source had the straight info on what would fit properly.

Thanks int. I have a much better feeling about it for when I do get some new wheels. I'm probably just going to get them for the NE winter and put winter tires on them and keep the contis on my stock rims. Or I may do it the other way. I just want to make sure I know what people are talking about so I don't look or feel like a retard.
Research is always key. And I research pretty much everything that requires me to spend money |
