Will these wheels fit on the front? 20x10 et15

[reggie01se]

Hey everyone, I've searched and found lots of threads for other cars but not specifically for an M6 GC. I have some wheels from my previous vehicle that I'd like to try and put on my GC. I'll be swapping the stock tires (343m) onto these wheels so I want to be pretty sure it'll fit before I take it in to have them mounted. It's a square set up:

20x10, et15

I'm confident it will fit in the rear, but the fronts I am worried about. How much can I expect it will poke? I've used those online calculators, and they range from 0.6" to 0.9", which I feel is a pretty big difference. I think I can live with 0.6", but getting to 1" is a lot. I won't be lowering the car, as all my previous vehicles have been slammed and I'm just tired of angling all the time.

Any thoughts would be greatly appreciated!

If you are running 265/35 same as OEM tire they come out by 22mm. I would suggest that you hold a plumb from the fender down and measure the distance to the tire. Normaly 15mm shouldn’t be a problem. 20mm could poke out by 5-8mm depends on the tire brand.

Thanks for the input! Yes I'm using the stock 265/35 tires. Eyeball test looks like the stock wheels are already pretty flush with the fender, but you're right I should check with at least a straight edge and confirm

I think 10mm spacer on OEM rims are ok. If you transfer this to the rims your choice 1/2” wider and 15mm ET. They will poke out by around 5mm.

these are 10" wide with offset 31. 16MM difference is .6"
KW HAS = lowest setting
Alignment = even tire wear

Thanks for posting this! Yeah it looks pretty flush already, so my wheels will def stick out a bit. Hopefully not by much. I'm not lowering the car so hopefully it doesn't look ugly

Does anyone know if going from ET31 to ET25 gonna be an issue with hitting the fender?

Have to get a HAS KW installed but my front 20x10 wheels are ET25 running 265/20 and my rears are 20x11.5 et18 running 305/20

Trying to figure out and been searching if my current set up will not work if I lower.

Thanks

I actually added 5MM spacers all around yesterday. My front is 10"et26 with 11"et10. It doesn't hit the fender but....there's always a but...even w/o the spacers I can see rub marks. Barely, just enough to leave a mark & remove tire gel. I've already been up & down some fairly steep driveways approaching in a 35 to 45 degree angle.
On my E60 M5, the front actually rubs on the front bumper just right below where it meets the fender.
