BMW G-Series

MMR37-1612 / 1615

Why fit?

Improve the aesthetics and dynamics of your BMW G-series with the MMR Hubcentric Wheel Spacers & Bolt Kits. As one of the most cost-effective modifications you can make to your car, these 12mm, 15mm or 18mm lightweight aluminium spacers will give your vehicle a wider stance to improve both handling and appearance.

Benefits of fitting?

MMR’s Hubcentric Wheel Spacers & Bolt Kits are one of the best and most affordable upgrades you can make to your BMW. Once installed, the increased track width not only improves your car’s appearance, but also enhances driving dynamics with greater stability.

By physically moving the wheel further away from the hub, these spacers give your wheels the desired offset needed to create the stance or look you desire, flush with your wheelarches, whilst also providing the additional clearance necessary to fit over bigger brake calipers or coilovers.

The MMR Spacers are sold in pairs in your choice of 12mm, 15mm or 18mm in width, including ten Carbon Steel grade 10.9 replacement black wheel bolts with each pair. It's essential that these longer bolts are fitted - not all spacers come with these included. By selling in pairs, you can mix your spacer widths front to rear to allow you achieve your perfect stance.

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 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.

Cleaning Advice.

• As with all anodised finishes, do not clean these spacers with aggressive acidic or alkaline cleaners otherwise the appearance of the finish will be damaged.
• Use only pH balanced cleaners (ie, non-acid, non-alkaline, non-solvents). Never use ANY type of wheel cleaner or any chemicals including abrasive compounds on the spacer. We recommend washing with water and mild soap. We advise against using commercial carwashes who use aggressive chemicals such as TFR.
