G80 M3 wheels fitment 19x9.5 ET20 all around lowered on H&R springs.

[Slow991tts]

Hello, I need some guidance here.

Will 4 - 19x9.5 ET20 wheels from a BMW G80M3 with 275-35-19 tires fit our cars, I'm currently lowered with H&R springs.

I know the fronts will fit on a stock suspension, but I'm concerned about the FRONTS since i'm lowered on HR springs and the REARS the offset being ET20.

Will I need to run spacers on the rear? I don't mind changing the tires. Any help will be greatly appreciated it.

Thank you

Rears will fit fine without spacers. Fronts should also fit fine without spacers pending what camber you have. Assuming it's stock camber, it "should" still be fine, but I would suggest test fitting. The fronts will be tucked inside the fender given the total diameter of the tire is a good bit taller than OEM so it'll look a little wonky.

I run 18x10.5 +22 front and 18x11.5 +36 rear with a 275/35/18 and 295/35/18 tire while on H&R springs and stock shocks. The 1 and 2 inch narrower wheels front to rear you reference will be fine, with the caveat of tire height in the front and camber potentially needing to be a bit more negative.

275+20 in front seems to be on the aggressive side and whenever you're on the bleeding edge of fitment very small details like exact tire brand, ride height, camber and method of alignment will affect clearance.

FWIW I run 275+27 in the front and measuring the contact patch to the edge of the arch lip of the hood gives me roughly 10-15 mm space.

Pic for reference. Running -3.0 camber in front using top hat camber plates. Tires are Nankang CRS in 275/40/18 (same overall diameter as 275/35/19) which run on the dummy thicc side vs narrow MPSS. Hub center to fender lip ride height is 333 mm. Need to caveat that this is mounted on an 11 inch wheel which does stretch the side wall but shouldn't have widened the tread shoulder too much more than a 9.5.

Contact patch reference here where the shoulder is feathering:

I do not rub on the hood itself but the tire did self-clearance this small portion of the front bumper here.

Also for additional perspective lowering on stock top hats probably gets you around -2.0 camber in front (depending on static ride height) and on a 26.5 inch tire each -1.0 degree of camber gives about 10 mm of clearance.

I think you likely will clear the hood but may see more interference on the bumper. All depends on your setup, pain tolerance and desire for flushness.
