MMR Performance

Sharper stance. Better feel. Simple upgrade.

Give your BMW F-Series the arch-filling look and planted road manners it deserves with this MMR 12 mm track widening kit complete with longer wheel bolts. By bringing each wheel outward by 12 mm per side, you gain a wider footprint for improved stability, cleaner fitment, and a more assertive, factory-plus appearance.

Why this MMR set works

Each spacer is precision CNC machined from lightweight aluminium alloy and features a hub-locating lip that matches the OE centre bore. That means true, vibration-free rotation and the confidence of OE-like refinement, while correcting offset to achieve the flush, symmetrical look enthusiasts want on either axle.

• 12 mm per side to widen the track and achieve a flush arch-to-tyre finish
• Hub-locating design for precise centring and smooth, shake-free driving
• High quality aluminium alloy construction to keep unsprung mass low
• Supplied with extended-length wheel bolts for correct clamping and safety
• Sold as a pair for one axle, suitable for use on the front or the rear
• Great value handling and styling enhancement for BMW F-platform cars

Real-world results

Expect crisper turn-in, a more planted feel through fast bends, and that desirable flush fit that tidies up the body-to-wheel relationship. We run these on our own MJ Modifications builds, and customer feedback consistently praises the perfect fit, arch-fill, and confidence-inspiring driving feel.

Fitment and setup

Designed for BMW F-Series applications using OEM-style bolt-on wheels. This set includes two 12 mm spacers and matching extended fixings for one axle. Many owners choose 12 mm on the front and tune the rear to taste; always check brake caliper, arch, and tyre clearance on your specific setup before driving.
