Wavetrac LSD for BMW M3, M5 & 3 Series
Wavetrac helical limited slip differentials for BMW cover the M3 from E30 through E46 and E9X, the M5 (E34, E39, E60) and M6 (E63), the 188, 188K and 215K rear axles used across the 1, 3 and 5 Series, and the classic 2002. ARP ring gear bolt kits for the 188/188K/215K axles are listed alongside.
Choosing the right Wavetrac
BMW Wavetracs are matched to the axle size (168, 188, 188K or 215K) and the final drive ratio range, so check the ratio on your diff or in your build data. Our BMW listings suit axles with a bolted ring gear; some later E8X/E9X axles have a factory-welded ring gear, which requires a different approach.
Installation & gear oil
Each Wavetrac is supplied as a complete differential carrier ready to accept your factory ring gear. Transferring the ring gear and setting backlash and bearing preload should be done by a professional driveline specialist. No break-in is required. Use the manufacturer-specified gear oil, avoid limited slip friction modifiers, and never use Red Line ShockProof or similar oils - they void the Wavetrac warranty.
