Wavetrac?: Designed from a clean sheet using state-of-the-art knowledge and engineering to be a better differential than any other. It uses a patented design to improve grip in low traction conditions.
Wavetrac?: Gives you quicker acceleration and faster cornering by driving both drive wheels instead of just one. And, it offers improved no-load performance when compared to other helical gear differentials on the market.

notes:
Our new Install Kit allows fitment of a Wavetrac? differential in late-model rear axles of 135i and 335i models where the ring gear is factory welded to the standard differential.
Since March, 2007 production, BMW has fitted rear axles where the ring gear is welded to the differential carrier. Until now, this process has hindered enthusiast owners? ability to upgrade, but no longer: Autotech Driveline now offers a precision solution at a reasonable price.
Upon receipt of a customer?s differential/ring gear assembly, the ring gear is separated from the stock diff using CNC equipment. The ring gear is then machined, drilled and threaded to allow bolt mounting to a new Wavetrac? differential.
We then return to the customer:
? Wavetrac? Differential
? Customer?s machined ring gear
? Precision-ground spacer ring
? Set of 10 ARP? ring gear bolts
For the best possible performance, disassembly of the stock axle, and fitment of the Wavetrac and Install Kit should be performed by one of our Specialist Dealers. This ensures that the condition of the axle can be assessed before modifications are performed, and that the re-assembly is done professionally - ensuring correct gear backlash and bearing end play.
