F80 M3 / F82 M4 Wheel Offsets (ET) and Sizes

[JoshFND]

Have seen some amazing set ups here.

Think I'm close but want to get some feedback if possible.

For a M4, and I have had all previous cars with aggressive[IMG][/IMG] fitment, coils and slightly stiffer spring rates.

(rear and front of my old car... coils, rear lower and upper Adj arms, camber plate and stock body panels minus a light fender roll..
20x 9.5 and 20x10.5 daily driven..)



For the M4..

option 1
19x9.5 + 35
19x10.5 + 22

Option 2
20x9 + 20
20x11 + 25

I don't mind a slight stretch on tires to accommodate the lower offset and fitment...

Will any of these options work??

20x11 et25 with 285/30 PSS works without any issues.

Looking to run 18x10 18x11 with 275/305 tire setup without rubbing.
What is the ideal offset to run for front and rear?
Any benefits running 18x9.5 over 18x10 for the front?
What is the lowest offset I can run on 18x10 18x11 without rubbing on 275/305 setup?
Planning on being lowered on CO's as well.

Any chance you could post the same info for the competition and CS wheels, sizing, tires, color options?

[spy963]

Tire size please ?

20x9.5 ET 22
20x10 ET40 or 20x11 ET35

I have KW HAS on the M3. I don't want to rub and I don't like stretched tires.
What do you suggest ?

Thanks !!

20x10 & 20x11 265/30 & 285/30
20x 9.5 & 20x11 265/30 & 295/30

Just to have same stretch front & rear

Edit: in both cases you gonna have some stretch....

Set-up looks good..

Do you by any chance have some more shots of your car with the rims? Are those E88.

Thanks

Thx for the info. I used your info for buying wintertires.

I have this in my staggered set up. 18x10 et 22 and 18x11 et 43. I chose et 43 to be able to accommodate a 315/30/18 tire if need be.

Question for the brain trust here. I have a set of VMRs that came off my wife's old F31 that I want to re-use as a winter setup on an F80.

18x8.5 ET35
18x9.5 ET45

Looks like the offsets are all wrong for the F80 but I can correct that with spacers? Or am I trying too hard to make these work? I think I can safely run 255/40 (not 255/45) R18 all around.

Thanks in advance.

For the front, 12mm spacers would have the outside as same as stock. Would have to check for the rear, it is 14 mm if you had 8.5et35 in the rear like I do. I did some comparisons using the 1010tires calculator.

Tire size is taller than stock, but might be fine on stock suspension.

Oops. Meant 255/40 R18. Will update post above.

Having 2nd thoughts - can't find unstudded Hakka's in that size for 18s. Can get 255/35 19s tho. Might have to pony up for new 19s in correct offset w/o spacers.

I am running 255/35/19 PA4 on my 340 and trying too figure if change for next winter. Would really like Hakka 9 w/o studs, hopefully before next winter. I have 19x9 et 35 with 10mm spacers that work fine on my M3 I would put on.

Thinking of running 20x10.5 et22 w/ 275/30 tires...Any advice? Would this work?

Went with Apex EC-7, 19x9.5 ET22 for the winter setup. The Hakka R3 big blocky treads squirm and slip like mad on dry roads. Fun, although I hope I don't burn through them before the next snow!

Hey, can you get a shot of how flush the rears are? Tempted to get these rims for next winter.

[NTMR_M3]

Having an issue with my fronts rubbing on my Coilovers (KW V3)
Wheels are 20x10 +16 w/ 265/30/20 PS4S

The inner barrel was rubbing on the spanner nut, and tire rubbing the spring. Threw 5mm spacers on and it is still rubbing I haven't got an alignment done yet (but my previous wheels were pretty close to the same spec (only in 19s) and I had no issues.

Any ideas? Wheel co. doesn't think they should be rubbing either. Is my tire too wide?
