As a byproduct of the Slicer Paddock x Future Classic wheel program, we have proudly produced precision-machined reducer rings for the coveted BBS E92 M3 GT4 wheels.
Despite the wheel's handsome looks, they never got the notoriety it deserved because of a peculiar feature: the 18x9.5+25 pair has an odd front center bore (77mm in fact), while the 18x10+40 variant carries BMW's conventional 72.56mm. Our reducer rings allow you to run the 9.5" width wheels can be run as intended and even accommodate a spacer should you desire a more exacting front fitment.

- Set of two (only required for the 18x9.5" wheels)
