F80 F82 F83 F87 F10 F13 BMW M2 M3 M4 M5 M6 Wavetrac ATB LSD 30.309.160WK

The Wavetrac 30.309.160WK is a true mechanical ATB helical LSD for F80, F82, F83, F87, F10 and F13 BMW M cars - including all 210 e-diff models. No electronics, no coding on non-e-diff cars; e-diff fitments need a simple remap.

• Patented cam mechanism delivers torque bias even when one wheel lifts - unlike standard helicals or OEM M Active diffs
• Made from 9310 alloy steel gears, case-hardened housing and ARP fasteners
• Engineered in the USA for fast-road use, track days and spirited daily driving
• Full lifetime warranty, transferable and motorsport-approved
