Help: Will these wheels fit???

[JNoSol]

Hello M5'ers. Please help me with this question.

I have a set of BC Forged RS41 from my F85 X5M. Once my M5 is lowered on KWV3, I would like to see if these would fit with OEM tires. Specs below, if they work then I would get a hub centric hub ring to convert 74.1 to 72.6 (which I believe M5s are). Would likely powder coat them satin black.

They would be on the aggressive side, but has anyone have the fitment experience to tell me if they'll work?

BC Forged RS41 Specs:
Front: 20x10J ET30 - hub bore 74.1
Rear: 20x11J ET20 - hub bore 74.1

M5 OEM Specs:
Front: 20x9J ET30 - hub bore 72.6
Rear: 20x10J ET34 - hub bore 72.6

Will use M5 OEM tires.

Fronts would work just fine. Rears are too aggressive IMO. You MIGHT be able to do 295/30 without rubbing.

Thank you. I'll use OEM tires, probably need a bit of spacers in front to match the aggressive rear. Maybe 10mm?

Yeah, 10-mm should even out the aggressiveness of the rear, but that might put the fronts in risk of rubbing also... I would do it nevertheless cuz you can always take them off if they do.

Sick rims btw! Looking forward to seeing them on.

Thank you. I think the black chrome should work on Singapore Grey.

First of all the front M5 OEM is ET32 not 30 but it's fine and will work.
second the rear of your RS41 is standing 14 mm out and I'm sure it works with 295/30... I believe 10 mm spacer in front is a good idea and I have seen people with 12 mm spacer (OEM rims) and no rubbing issue... Don't forget to post the pics after installing this nice rims

Thanks. OEM 19" front are ET32, but 20" are ET30. Not much of a difference though, lol.

I calculated, this would make my rear 25mm more aggressive and front 13mm more aggressive. So 10-12mm front spacers.

I think I would have to roll my fenders and slam the car. Otherwise, it will rub. I'm worried this is 10mm too aggressive for my taste. 20x11 ET30 rear would be perfect, dammit...


I think it's best to sell my F85 X5M wheels and buy a new set. Too aggressive of a stance is soooo 2011.

Below is 15mm spacers. My setup would be equivalent to 25mm spacers in the rear.

Teaser TEST fitment of the BC Forged RS41 from my X5M. Keep in mind my X5M tires are on there, the tires are too big for the M5. It would look much better with M5 OEM tires. Just need to be lowered and fender rolled. I don't think front spacers are needed. The front is perfect.

Thoughts everyone?

Should I go satin black of keep black chrome?

^^^Obviously with these tires there is rubbing issue (on rear). what size are these tires? 315 or 325?

Yeah, there's no way I could run those tires. They look like an X5, lol. 275/40/20 front and 315/35/20 rear. Will use OEM M5 tires.

Wow, that looks good! I'd keep the black chrome.

Lowering will definitely help the fitment for the wheels... So it won't look as "sticking out" as much.

Thank you. Yes, with M5's narrower OEM tires they would be flush. Lowering it and fenders rolled would be a very tight tuck. I'm just not certain if I want such an aggressive setup. It's 25mm more aggressive than stock in the rear, and 13mm more aggressive in front.
