So what size of spacer would be needed to clear the stock calipers on an M3/M4 with on the GT4 wheel? No one seems to be able to post an exact size.. everyone just says 25 mm. If it is 25 mm one would be at +5 effective offset and with a 11 inch rim, that is pretty aggressive... if this is the case, to gain half an inch of wheel size isn't worth it so again, the BBS wheel would be the clear choice.
You are welcome - happy to help when I can. It's not the caliper that's the issue. It's the suspension. Based on my research I believe only a 12mm spacer is needed with a 295. However I will know more after I do some testing. I will test on my e92. The e92 and the f8x have very similar front fitment / space.

You are welcome. The RIA is not being discontinued as far as I know.

RIA is an amazing bang for buck IMO.
