Wavetrac LSD for Porsche 911, Boxster & Cayman
Wavetrac makes one of the widest ranges of helical limited slip differentials for Porsche, covering air-cooled 911s through to the 991 GT3 and Turbo S, plus 930, 944, 968, and Boxster and Cayman. Units are available for 901 and 915 gearboxes (by spline and offset), the G50, 996 and 997 six-speed manuals, the 987 and 981/718 six-speed, and the PDK in both factory open-diff and factory-LSD versions, plus the front diff for AWD 993, 996 and 997 models.
Choosing the right Wavetrac
Porsche Wavetracs are matched to the gearbox, not just the model. For 915 gearboxes check the spline (18 coarse or 43 fine) and offset. For PDK, the factory open diff (85mm bearing journal, G91) and factory LSD (91mm, G100) take different units, and the 991 GT3 / Turbo S (G160) uses an alternate bolt pattern. OEM PDK carrier bearings are listed here too.
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.
