Ride-height adjustment is built into the mount. Set to the Lifted position and paired with the MMX Front Differential Lift Mount / Cradle (MMR55-1604) and Rear Diff Bushes (MMR55-1603), it raises the differential by 10mm at all four mounting points, correcting driveshaft angles on lowered cars.

Features

• OEM or Lifted (+10mm) mounting positions
• Direct bolt-in replacement for the factory mount, no cutting or drilling
• Part of the modular MMX F8x differential system
• Supplied without bushes (see MMR55-1603)

Fitment

• BMW F87 M2 / M2 Competition / M2 CS
• BMW F80 M3
• BMW F82 / F83 M4

Use one for a simple rear upgrade, or two alongside the MMX Dual Differential Mount and Front Lift Mount / Cradle to complete the full four-point differential system.

Features

• BMW F87 M2 Competition / CS (S55)
• BMW F80 M3 (S55)
• BMW F82 / F83 M4 (S55)

The 80A polyurethane bushing is firm but keeps a small amount of the articulation the factory design relies on, so you get extra precision with only a minimal increase in NVH, suitable for road and track use.

Features

• Black anodised 6061-T6 CNC machined aluminium housing
• 80A grey polyurethane bushings
• Works with the factory shifter or a short shift kit
• Direct replacement, no cutting, drilling or modification

Fitment

• Manual BMW G87 M2, G80 / G81 M3, G82 M4

Simple yet essential upgrade for enhanced durability and reliability on and off the track.

Upgrading to an aftermarket exhaust system or increasing engine performance generates significantly more heat in the drivetrain area. With the exhaust sitting closer to the CV boots, this excess heat leads to premature cracking and failure of the factory rubber boots. Over time, this can cause grease leaks, CV joint wear, and eventual driveline issues—especially under aggressive track conditions. BMW’s response to this well-known issue is to fit CS/CSL driveshafts, which come at an eye-watering cost of over £2,000. MMX offers a smarter, cost-effective alternative that achieves the same level of protection without the need for expensive drivetrain replacements.

Designed for either factory or aftermarket exhaust systems.

MMX heat shields are engineered to provide a strong, effective barrier between your CV boots and the intense heat radiating from your exhaust system. Whether you’re running a factory or aftermarket setup, these shields act as a protective layer to deflect heat away, ensuring your drivetrain components last longer under demanding conditions. Precision-crafted from T6-6062 aluminium, our heat shields are both lightweight and durable. Our signature MMX polished and anodized gloss black finish not only enhances thermal dissipation but also provides a sleek, factory-like appearance.

// MMX heat shields create a protective barrier to deflect heat away from CV boots, preventing premature wear.

// By reducing radiating heat, our shields help extend the lifespan of rubber CV boots and prevent drivetrain issues.

// BMW’s solution is to install CS/CSL driveshafts, costing over £2,000, while MMX offers a cost-effective alternative.

// Easy 15-30 minute installation and fully reversible.

// Made from lightweight, durable T6-6062 aluminium with a polished and anodized black finish for optimal heat dissipation. // Includes all necessary hardware for a hassle-free installation.

Designed with one aim in mind: to help achieve optimum suspension performance and geometric accuracy, and thus increase the effectiveness of your rear anti-roll bar. Each heavy-duty, high-articulation rear drop link attaches the rear anti roll bar ends to the lower suspension arm. Replacing the failure-prone, weak plastic OEM links with our rigid billet aluminium links greatly reduces flex and allows a sharp, uncompromised transfer of suspension movement through to the sway bar.

// Manufactured from Aircraft grade T6-6061 aluminium billet.

// Complete OE replacements.

// Our single threaded adjusters make for easy length adjustment in-situ without having to detach and re-attach.

// Heavy-duty, high-articulation rear drop link.

// Anodised in signature MMX Gloss black.

// Heavy-duty ball joints to ensure a long life span.

// Kit complete with everything you need.

// Can be used with either factory or Aftermarket rear anti roll bar, and returned to standard at any time.

// Rubber boots for longevity and durability. // Sold in pairs.

The MMR Lowering Spring Kit is one of our best-sellers. Little wonder, as they’ve earned a reputation for delivering the perfect blend of improved handling, enhanced looks, all without sacrificing ride quality.

The drop in ride-height makes a huge difference to the handling characteristics: by lowering the M3 G80’s centre of gravity, it reduces body roll for better dynamics, whilst maintaining the ride quality and comfort of your car.

Thanks to the carefully selected progressive spring rates the ride-quality remains unaffected and is actually nicer to drive at slower speeds. But push-on through the corners and the G80 chassis really comes to life, making it feel lighter, more direct and with significantly sharper turn-in.

Meanwhile, the car’s appearance is transformed. Our development has resulted in the springs providing a drop at the front of approx 35mm whilst the rear sits lower by 15mm. By getting rid of those nasty wheelarch gaps, it’ll look just how it should have come from the factory!

Go lower or stiffer than these MMR Springs and your car will bounce and crash as the dampers are mismatched to spring-rate, and the springs themselves run out of travel.

Finished in MMR Metallic Grey, the Sport Springs are developed to be fully compatible with cars fitted with either static or Adaptive M adaptive dampers. A must-fit for any M3 G80!

FEATURES

• Carefully optimised spring rates for improved driving dynamics
• Designed to be compatible with Adaptive M and static factory dampers
• Lowers vehicle by approx 35mm front and 15mm rear
• Powder coated in MMR Metallic Gunmetal Grey for a durable finish 
• Fitments for RWD and xDrive
