10,5" wheel upfront

Shirex · 01-14-2022, 01:21 AM

Hi, has anyone fitted a 10,5" wheel upfront on m5? I know it's not the ideal size but i have a set of rims on hand i can buy for cheap, but they are 10,5" et38 in front. Guess i atleast need spacer to clear te strut but i have no idea how far out they will go.. Want to run a 275/35/20 tire if possible.

Probably not a good idea if it's not approved by BMW and 275 tyre would be too slim for the wheel.

The 10.5" width is actually within the range of the 275/35/20 tire (9" to 11").

As far as it sticking out, the outer edge will be as far out as a 9.5" et 25. So it'll be ok.

The problem I see is 1) clearing on the inside (as you mentioned) and 2) clearing your brakes. M5 brakes are massive.

Yup, they are huge. I've got a friend who's got the same rims, but they are 9,5 wide, have not had a chance to measure and check for myself how much room there is to spare on his. Atleast he is clearing the brakes, will adding an inch to the rim with the same ET affect caliper clearing? in my head it wont but honestly have no idea. The rim is "flat" inside so i guess it is the same room for the caliper anywhere inside it

Unfortunately, I don't think it matters if you add that inch. What matters is the face type and disk type. Was the 10.5" wheel used as a rear wheel previously? If so, you will most likely need spacers to clear the front brakes
