Looks great what is the process and I notice you have parking sensors. Did the extenders have the hole in them or you had to put 1 in???

As per installed Pic #7 the extender portion for the front bumper stops short of the sensor so no need to drill anything

NICE!

Wish there was something like this for the F32 - looking to get APEX VS-5RS staggered wheels using 245/35-19 front/275/30-19 rear but Apex states will prolly rub & must roll fenders

current offsets are 19x8.5 et 35/19x9.5 et 40 which puts those tires flush to my fenders with no rub/ Apex wheels will move combo out by 5mm

They should be available on the M240i with ZTK package it seems... Are they not available via the dealer parts desk?

Also, I'm not really seeing the point here. It's like like the actual fender is flared - all you're doing is adding a little extra width to the body to meet the regulations so that a wider wheel doesn't "stick out" too much. These aren't creating more room to stop rubbing, right?

I will say BMW did a better job that VWoA with the new Golf R and the goofy little plastic pieces they clipped to the fenders.

Looks great! Have you mounted the rear portion yet?

What front lip are you running? LCI?

If the fender flat area width (where the mounts for the fender flares are installed) is the same for F and G series then there’s no reason why these g42 flares wouldn’t work on yr F32

I'd love to see the rears too! I just mounted some aggressive 295s on the rear and would love to add these for better aesthetics

Hello, I saw the rear arch piece might not fit due to the edge of the rear passenger door limitation. So do you think it will fit perfectly?

Important to note that even if there was something similar available for the F32, these don't change the inner dimensions of the wheelwell at all.

If a setup rubs the inside edge, adding external adhesive extensions doesn't change that. This applies to the G42 2 series ZTK fenders as well.

sorry to crush dreams

I know a guy who has G80 wheels: 19x9.5+20 + 20x10.5+20

He spent ~$1000 on fender cut+rolled+rewelded and then wrapped the car instead of repainting fenders

(Car is dirty from recent rain)
