Looking to fine tune the Wavetrac LSD power delivery together with stiffer suspension settings (stiffer Tarett GT Swaybars and stiffer Ohlin compression and rebound) and Hoosier A7 race tires as my seat time increases with this mod. The Wavetrac operates with a gear drive and simple sliders that apply power to the unpowered side (wheel off the ground) seamlessly. No need to turn off the PCM except for the standing start. Mooty's quote was before the development of the Wavetrac, which takes the same spot as the Torsen, Quaife, Giken and other ATB's, but is more effective powering the lifted spinning wheel.

"dont just put an LSD on your car.
figure out why you need it.
if you drive on street, even if you drive recklessly, you DONT need LSD. it either make you understeer too much or its presence is not felt, money wasted.
if you AX, you most likely need torsen.
if you track, DE, or race, you need plate type. torsen wont work if you lift wheel off ground and that's what happens if you are in the tight turn on track.
if you are spinning inside rear tire (when the tire is on the ground) you need stickier rubber. cayman s at 295hp shouldn't be spinning rear inside tire if it's on dry pavement with good rubber (notice, i said
ON the pavement) if you are lifting tires, you need plate type.
grossly simplified, yes, but this is the gist of it."
Another owner's experience!
I've now got 18 days on track with the Wavetrac and I'm very happy with it. The car is VERY stable under hard braking and it's fantastic coming out of corners. I've had several experienced drivers either drive my car or ride along this summer and all have commented on the excellent handling. I also have JIC Cross Competition coilovers, neg 2.1 camber front, neg 2.3 rear, stock LCAs, BFG R1s and Pagid Black front/Orange rear.
And from Wavetrac the benefits include-
Handling is greatly improved with a Wavetrac differential as more torque can be transferred to the ground under fast cornering. This ensures a faster and tighter turn, and a huge improvement in vehicle stability. Traction from a standing start is improved as more torque can be transferred to the ground without the risk of one wheel spinning. This has huge traction benefits to powerful rear wheel drive vehicles such BMWs or Mercedes.
So, the Wavetrac takeaway is-
- Throttle on out of corners much better than open diff
- Very stable under hard braking than open diff
- More stable through slalom features than open diff
- Improves standing start traction
- If you are lifting inside tires, Wavetrac transfers torque from the unweighted tires to the outside drive wheel
