Hello. My car is f33. I got the f8x brake and a disc set. But the disc doesn't fit. What can I do ? Please help me.

Don’t think it can be done; found this old thread here talking about the differences but wasn’t successful in the end for all i know

You can use the calipers but you cannot use the same discs because the F3x caliper mounting point on the knuckles are different than F8x vehicles.

You'll need to get the 370mm front & 340mm rear discs meant for 335i/340i/435i/440i M Sport brakes because the F8x discs are too big to fit on F3x cars (F8x discs are 380mm front & 345mm rear)
