It increases oil capacity up to 2 litres, giving the differential a larger reserve to draw on through sustained track use and hard road driving.\u003c\/p\u003e\n\u003cp\u003eAn internal windage tray keeps gear and pinion lubrication constant regardless of load or cornering forces, while also reducing component drag. Less oil churn means less parasitic loss through the drivetrain, and more consistent lubrication where it's needed.\u003c\/p\u003e\n\u003cp\u003eInternal and external cooling fins increase the sump's surface area, improving oil cooling and helping the differential hold a consistent operating temperature under repeated hard use. A -8AN port, supplied with an M22 to -8AN adaptor, allows the sump to be run with an external cooling setup for anyone pushing the drivetrain further.\u003c\/p\u003e\n\u003cp\u003eThe windage tray is built extra wide, giving perfect compatibility with Drexler and other F8x M2, M3 and M4 mechanical limited-slip differentials straight out of the box.

Run on its own in the OEM position, it adds a genuine second point of support to the diff, tightening up the connection to the chassis and reducing unwanted movement under normal and increased torque loads.\u003c\/p\u003e\n\u003cp\u003eF8x diff mounts are a known weak point on this chassis, prone to tearing and premature failure under hard use. The Dual Differential Mount is a direct answer to that, adding real reinforcement rather than just stiffer rubber in the same single mounting point. It can be run with the factory bushes for a like-for-like fit, or with two of the MMX Rear Diff Mount Bush (MMR55-1603) for a firmer, more connected setup.\u003c\/p\u003e\n\u003cp\u003ePaired with the MMX Front Differential Lift Mount \/ Cradle (MMR55-1604) and set to Lifted, the same mount raises the differential by 10mm.

Lowering an F8x or G8x M2, M3 or M4 changes the geometry of the rear axle, placing the driveshafts under an angle they were never designed to run at.

For a full 4-point setup, the MMX Dual Differential Mount (MMR55-1606) is added alongside a second raised bush, giving further control over differential movement at the corrected, lifted height.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eF8x Pairing\u003c\/strong\u003e\u003cbr\u003ePaired with the MMX Rear Diff Mount Bush (MMR55-1603), the cradle forms the 3-point setup at OEM height.

Machined from billet 6061-T6 aluminium, they replace the factory rear toe arms with a stronger, more precise component built to hold up to sustained track and road use.\u003c\/p\u003e\n\u003cp\u003eAt the core of the design is the pillow bush rod-end, which replaces the OEM rubber bush. The stock rubber bush flexes under load, letting rear toe settings shift as cornering forces and acceleration loads build up, whereas the pillow bush eliminates that deflection, so the toe setting stays consistent under hard driving. This gives more predictable handling from corner to corner, reduces uneven and premature tyre wear, and helps keep tyres in their optimal temperature window under acceleration and cornering. A rubber boot on the rod-end protects the bearing from road grime and moisture, so it holds up over time under both daily road use and repeated track sessions. The net result is sharper chassis feedback and a car that responds more predictably when pushed hard.\u003c\/p\u003e\n\u003cp\u003eInstallation is a direct bolt-on replacement with no cutting, drilling, or permanent modification required, and the arms are fully reversible if you ever need to return to the factory setup. That makes them a low-risk, high-reward upgrade for track-focused and fast-road builds alike.\u003c\/p\u003e\n\u003cp\u003eOne important consideration for buyers running lowered G8x\/F8x M-cars: because these are multi-link rear suspensions, the toe arm's operating angle is tied to ride height. Lowering the car reduces the usable range of toe adjustment and pushes the arm toward settings that increase minimum camber, which in turn accelerates tyre wear. Anyone running lowering springs or coilovers should factor this in when planning their alignment setup.\u003c\/p\u003e","brand":"MMX Performance","offers":[{"title":"Default Title","offer_id":55459357720913,"sku":"MMR55-1609","price":360.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1089\/1952\/1617\/files\/Artboard1-8.webp?v=1792870694"},{"product_id":"mmx-performance-rear-camber-arm-bush-for-bmw-m2-m3-m4-f8x-g8x","title":"MMX Performance Rear Camber Arm Bush for BMW M2 M3 M4 F8x G8x","description":"\u003cp\u003e\u003cstrong\u003ePrecision Camber Arm Bearing.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MMX OEM Camber Arm Bearing is machined from billet 6061-T6 aluminium to replace the factory rubber bush found on BMW G8x and F8x M2, M3 and M4 models.
