M4 Fitment

[Beach3um]

Intrested in ordering wheels. Looking for most aggressive fitment you can fit with 19x10 and 19x11 on springs or coilovers? I've seen posts with the typical Apex fitment. But want to see more options if any ???

your request is a little too vague to gain more information that what is already available out there.

You need to define exactly what brand suspension, ride height, alignment specs, and class of tire you want to run first before you can start looking at the fine details of getting "the most aggressive" fitment.

Ok.not bagged fitment but aggressive coilover fitment without crazy camber.
The most seen offsets I see are 19x9.5+25 19x11 +43.

That is still too vague. Do you care about aggressive tire width for maximum traction, or do you just care about aggressive wheel/to fender flushness, or both?

Let me elaborate then:

So we know you want 19" wheels, a staggered setup, and no crazy camber, so your equation should probably start as 19" staggered wheels with stock front camber (roughly -1.75 lowered) and -2.0 camber in rear.

Now you need to determine how wide of a rear tire you want. Depending on that answer, that will determine what front tire sizes will work properly while keeping with the proper front-to-rear overall diameter (ratio or percentage). Once the tire widths are decided, then you can move on to determining which wheel width will properly fit your chosen tires. Then you can look at which wheel offset will provide the most aggressive/flush fender fitment. Then you have to pray that the wheel style you like is actually made in your desired sizes

Example: For a rear wheel, you could fit all these wheel/tire options that would make it look equally aggressive for flush fender fitment @-2.0 camber, but with different levels of traction available:

10" rear +20 with 275mm tire
10" rear +25 with 285mm tire
10.5" rear +20 with 275mm tire
10.5" rear +25 with 285mm tire
10.5" rear +35 with 295 or 305mm tire
11" rear +30 with 285mm tire
11" rear +37 with 295mm tire
11" rear +40 with 305mm tire
11" rear +43 with 315mm tire
11.5" rear +45 with 325mm tire

* the specs above all really specific tire dependent since not all tires are actually the widths that are indicated on the sidewall.

Great info right there MineralWhiteF80 -- and it lines up pretty accurately with my experience after running a few different aggressive fitments in 19" and 20".

Beach3um it sounds like aesthetics/aggressive looking fitment on a street car is what you're after vs. fitting the widest possible tires without rubbing. For that my suggestion would be:

19x10 +25'ish front (265 is probably max width tire)
19x11 +35'ish rear (285/30 tire is a safe bet, 295/30 is probably doable though)
