Wavetrac ATB LSD - M3 E46 / E92 (output flanges required, not included)

BMW M3 E46 and E92 Differential Upgrade by Wavetrac

Unlock serious traction and faster corner exits with the Wavetrac helical limited slip unit for the BMW M3 E46 and BMW M3 E92. This premium rear differential upgrade keeps drive going to the wheel with grip, giving you confident acceleration out of bends, sharper responses and consistent performance on fast road and track.

Why enthusiasts choose Wavetrac for M3

• Maintains drive when an inside wheel goes light over kerbs, camber changes or slick surfaces. The patented internal wave mechanism generates load when one side nears zero, so usable torque still reaches the tyre that can use it.
• Smoother, more predictable power delivery near the limit. Stay on throttle mid corner with greater confidence and stability.
• No push or understeer traits associated with traditional clutch pack units. Keeps the car neutral and responsive.
• Works transparently with factory stability and traction systems during normal driving.

Engineered for performance and longevity

• Carbon fibre bias plates support consistent behaviour from new mile one to high mileage use.
• 9310 alloy steel gearset inside a robust billet or forged steel body.
• ARP fasteners throughout for strength you can trust under hard use.
• Designed and manufactured in the USA to an exceptional standard.

Real world gains you can feel

Whether you are pushing on during a Sunday blast, running track days or chasing lap time, this M3 rear axle upgrade reduces wheelspin, adds corner exit traction and makes the car easier to drive quickly. Our team has fitted and driven Wavetrac on customer cars and our own builds, and the feedback is the same every time. More grip, more confidence, more speed. Smooth is fast.
