Whichever width you select, the MMR Spacers are of a Hubcentric design, meaning that they are machined with an alloy spigot to make for perfect centering whilst maintaining the OE 66.5mm centre-bore for the correct fitment with factory or aftermarket wheels. The Hubcentric lip ensures precise location onto the car’s hub, making them easier to fit and less prone to vibration through imbalance – all experts strongly advise against any wheel spacers that aren’t of this Hubcentric design on a performance car.
Of course, the obsessive manufacturing quality and design details of these Wheel Spacers are what you'd expect from MMR. They are precision machined from heat treated aerospace aluminium 7075 T6 for increased strength and durability, plus significant weight savings compared to cheaper steel or 6000-series spacers.
The coating is beautiful black-anodising to protect the aluminium from road dirt and corrosion. This surface treatment avoids the risk of "bonding" to the wheel or hub that can happen with cheaper finishes over time, and combines with the design of the rear mounting faces which feature cut outs to make removal easy even after thousands of road miles.
Finally, the subtle laser-etched ‘MMR’ logos are a nice finishing touch, just visible through your wheel spokes.
These CNC machined precision alloy wheel spacers come with a 66.5mm bore and 5 x 112mm PCD stud bolt pattern, perfect for all G-series BMWs.
