I see a lot of people use wheel spacers. Is this a cosmetic only mod or does it actually improve the performance in a measurable way? Are their issues that can arise from using spacers?

wider track will def change handling...
not cosmetic ONLY.... altho mostly cosmetic...
there's plenty of threads on this..

Try searching as there are a lot of threads on the pros/cons of spacers.
Wheel spacers are not only for cosmetics.
Pros
Pros
- Wider Track
- Less Weight Transfer
- More Brake Clearance
- More Stress on Studs
- Less Fender Clearance
- More Stress on Bearings
cosmetic only, unless you do something extreme
don't fall for the marketing hype saying your wider track will give you any better handling.

knifegun wroteThanks for creating this thread. I've read many threads on spacers.......But I'm still lost. All of a sudden when I had my mind set on using 15mm spacers all around, now I'm debating whether I should use spacers or springs since the stock suspension is brilliant already.....And I'd hate to mess with it.I see a lot of people use wheel spacers.

J08M3 wroteI would say its 99.5% for cosmetic and that last 1/2 a percentage in regards to wider track will help with the overall stability.cosmetic only, unless you do something extreme

Most people will not even feel any difference and on the track, you probably wont even see too much of a difference in times (if anything depending on the track it's going to be around less than a 10th of a second).
But it's not purely cosmetic, there are other slight benefits with it. For the most part though, what we market is the fact that it gives you that bulldog stance:
yea, it definitely looks better with spacers. I went 10mm all around. I didn't want to go too wide cause I think it looks ridiculous when the tires stick out past the fenders. Although I could've gone wider without that problem. Also the more your tires stick out, the more risk you run to throwing rocks and debris up from the tires onto the side of the car.
But it definitely looks better.

^^So do you think I'll degrade my M3's stock handling by going with H&R 15mm spacers all around combined with RD springs? (sorry, I'm very nervous on this decision since I would love to have the improved look, but I don't want to degrade the stock handling).
the spacers won't degrade it. The Springs probably will, but not to a point where it's going to make a difference unless you're on the track. In fact I wouldn't worry about it at all. Just get an alignment after everything is done and I'm sure you'll be happy with the handling.
The look will be great though

J08M3 wroteMan, it's a tough decision since I give more importance to performance compared to improving looks. If the springs or spacers affect the handling in the slightest negative way, I most likely won't get the springs/spacers.the spacers won't degrade it.

It's still a tough decision man.

Most use them on factory wheels or wheels that are not the correct offset to make them flush with the fender. They are for the most part cosmetic although some race applications use it to widen the track. For street use, they are entirely cosmetic.
I recommend going with a solid set like H&R which are forged alloy and will be resistant to cracking under stress.

I will drive my M3 extremely hard very often. That's for sure.

I'm now thinking of leaving the stock set-up alone...
Another question about spacers- will 18 front /15 rear give me a flush appearance with my fenders or will they be sticking out past the fenders.
I'm trying to get the flush look but don't know what size to order

That should really help out!

The link in Jurrian's post has plenty more pictures.
tom @ eas wrote15/18 looks good in those shots..almost flush..
So no issues with rubbing during turning at 15/18?
Khurram wrote18/15 looks great with 19"OEM wheels. I was concerned that the look would be too aggressive, but I went for it anyway. I couldn't be happier. The wheels look flush and do not stick out beyond the fenders. I haven't seen any damage from rocks hitting the rear fender, but that is somewhat of a concern. IMO, OEM wheels look alot better with spacers.Another question about spacers- will 18 front /15 rear give me a flush appearance with my fenders or will they be sticking out past the fenders.
