MMX Hubcentric Alloy Wheel Spacer Kit for BMW F Series & G Series 5x120 72.6 / 5x112 66.6 - 12mm 15mm 18mm - Extended Bol

Give your F Series or G Series performance car the flush, purposeful look it deserves with MMX hub-centric spacer kits. This simple stance upgrade pushes your rims out to sit neatly in the arches, improving stability, steering feel and cornering confidence while transforming the visual presence of your car. Lightweight aluminium construction keeps unsprung mass low and the precision hub lip ensures perfect alignment for smooth, vibration-free driving.

Choose from 12 mm, 15 mm or 18 mm thickness to fine tune offset and track width for that desirable arch-fill and sharper handling response. Each kit includes the correct extended black bolts for a direct, bolt-on install.
