BMW 188K LSD Wavetrac Helical
A unique helical LSD for late model BMWs. A supurb option for your 125i, 130i, 325i, 328i, 330i, 525i, 530i and most other 6 cylinder BMWs with the 188 sized diffs. This is a quiet, predictable and long-lasting LSD unit. Backed by a lifetime warranty which is transferrable should you sell the vehicle. The Wavetrac is the only helical design which will not spin the inside wheel should it lift off the road/track. The Wavetrac differs from a traditional helical, and has friction plates fitted which are replaceable and can be swapped for different plates to change the lockup behaviour.
