MMR Performance Hubcentric Wheel Spacers & Extended Bolt Kit (2x12mm + 2x15mm) for BMW F-Series - Aluminium, Black 10.9 Bolts

MMR 12 mm and 15 mm Hub Centric Track Spacers with Extended Black Bolts for BMW F-Series

Give your BMW F-Series the stance and road-holding it deserves with this premium MMR rim spacer and bolt bundle. The paired 12 mm and 15 mm offset correction shims widen the track for a flush, aggressive look and more confident cornering. The hub centric design keeps everything perfectly centred for a smooth, vibration-free drive, while the lightweight aluminium construction helps maintain sharp steering feel.

We run these on our own cars at MJ Modifications and have installed them for many customers. Feedback is exactly what you want from a stance and handling upgrade: crisper turn-in, improved stability through fast bends and a cleaner wheel-to-arch fit that looks factory-plus without compromising day-to-day usability.

• What you get: 4 spacers total, 2 x 12 mm and 2 x 15 mm
• Fasteners included: 20 x extended black wheel bolts, carbon steel grade 10.9 for strong clamping
• Fitment style: Hub centric for precise location on the hub and consistent wheel alignment
• Material: Lightweight aluminium spacers
• Vehicle platform: Designed for BMW F-Series chassis

Why this spacer kit is a winning upgrade

• Wider track for extra stability and confidence when turning or braking
• Flush fit look that pushes the rims to the arch for the perfect stance
• Offset correction without changing wheels, great with factory or aftermarket setups
• Correct-length extended lug bolts included to suit the spacer thicknesses
• Simple, cost-effective handling and aesthetic improvement with immediate results

How to use the mixed sizes

The kit contains a pair of 12 mm and a pair of 15 mm spacers so you can tailor front-to-rear fit. Many owners choose the thinner pair at the front and the thicker pair at the rear to balance arch clearance and visual poke, but choose what suits your wheel and tyre setup.

Installation guidance

• Clean hub and wheel mating faces thoroughly before fitting
• Always use the supplied longer bolts with the spacers
• Torque to the vehicle manufacturer’s specification and re-check after initial miles
• Verify arch and inner clearance on full steering lock and suspension compression
