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

[s4play]

I was considering LM-R with the AMUSE offets with specs:

20x9,+8
20x10, +18

Looks like these wheels may be TOO aggressive for the new F80 M3 since that is +21 more up front sticking out and +22 in the rear.

Maybe we will get those on the comp package... I sure wish there was an affordable forged wheel option -- <20 lbs

Those wheel specs on the Volk should fit the F80 perfect!

Does anyone know if the 19 inch f80 m3 wheels are forged?

18 x 9.5 offset 23 rear

I would like to know this as well.

use the 1010 tire wheel offset calculator and figure it out yourself. its really easy. I think I even posted how to do it in this thread

It says the fronts are in 6mm (6mm less clearance on the inside) and the rears are out 11mm (23mm more clearance on the inside). Not really sure if this means they can be used or not ... sorry wheels just aren't my thing.

6mm more sunk in in the front and 11mm more aggressive in the rear. It will look a little weird bc it will look weak in the front and strong in the rear.

BUT, considering that they are winter wheels only, probably would fit fine.

if you have CCB, these wont work because you need 19s for the clearance.

6mm less clearance still should be enough clearance in the front for stock brakes, but we don't know this for sure.

Thanks... I guess I'll have to wait and see.

$1200 for a set of 4 tires for the 19" rims sounds about right?

Guys I have a set of BBS CH-R new in box never used for a e92. The rears are 10.5 with a et40 offset and the front are 9j with et 24 offset what spacer do I need to make this work on F80 M3?

you will be +5mm in the front and +5.5mm in the rear vs stock, with a wider rear wheel

they will work well, just wont be tremendously aggressive. will be more aggressive than stock.

personally, I would say you will not be able to fit any spacer on those while maintaining rub fre fitment. it does depend on how much fender clearance the car has, which we don't know yet.

the only spacer that would fit would be a 5mm but I despise 5mm spacers and they almost always cause vibration and issues. any spacer without enough material to snap around the hub is too small. and even then, spacers are not ideal. the smallest spacer I would run on a bmw is a 12mm

Should I sell them? I wish they would exchange them. They are 2 years old but never used.

i think they will fit OK. depends if you like them or not. they will be a little more aggressive than stock. 5mm isn't much, but its noticeable

the one negative in my mind is that bbs chr are very heavy. but I do like the way they look

Another thing I forgot was if CCB will clear.

This! I have seen it both ways (forged vs. 'light alloy').
So, are the 437 M 19" forged?
And what do they weigh?

The thought of CCB w/ BBS FI wheels... Unbelievable reduction in unsprung weight!

Only way I will do BBS FI is if I can Insure them. Not driving around on our unkept american roads with 8k rims.

[stressdoc]

Only way I would do BBS FI is if I can find a set for a quasi-rational price -- used 5k...

Added the ETK parts diagrams/info.

So I think in time... we will know for sure.

Based on the latest parts catalog info, it seems that it is the images of the 640M and 641M that were in fact inverted in the OP. Might be worth fixing

CCB and BBS FI...you could buy another car with the cost of that setup!

Would be interesting though to know if the 437M are forged. Although I'd wish this, i doubt it's true.

is anyone considering 20"?
