Testing new Wavetrac front Diff...
I am testing the new Wavetrac front diff.
Looks like this:
I had one of the first quaife's in the country and it really made a difference on the track so I was really excited when Road Race Engineering offered me a chance to test one of these new diffs. My Quaife made a huge difference on the track, allowing me to rotate the car and maintain speed in the corners. My main complaint is that if you put a wheel off trying to gain a line or kick a rock into the car behind you, the dif could act like an open diff when it had no load or torque conditions.
The main advantage of the new diff is the ability to distribute power properly in no or low traction conditions ie: wet or dirt. I have really noticed the difference on a canyon run up angeles crest where there was water on half the road on a fast turn. The car just clawed it's way around the turn in a way I have never seen before. This was on shaved nto1's with no real grooves at a good clip.
I am really looking forward to testing this at the track. Will post observations soon.

Sweet looks good, i recently droped in a carbonetic LSD as well.
haven't had time to actually drive the car as the motor is out.
but you right in saying the gear LSD diff work like open diffs when one of the wheels gets of the ground... clutch diffs dont.
let us know when your done, is the diff compatible with ACD

Ya i have been looking at this for awhile now. Its a great concept and if the bugs got worked out "like any new part" Its going to be a great alternative to the ridiculous price and availability of the Quaife. Please keep up updated on your findings i guess i might have to be the one to test it at the strip..

For the competitor, this sounds great. For a daily driver, I'm not sure as I'm not a fan of clutch packs in a daily driver... as a rule. Granted this seems to be a little different... with friction "buttons". The sweet thing about the Quaife unit is that it's guaranteed for life. EVEN under racing conditions. I wonder what the service life of this unit will be? Looks like it should perform better than the Quaife unit.
Don't get me wrong, I'm ABSOLUTELY not bashing a product that I have no personal experience with. One would be a jackass to do so. Just posing questions that myself and other like minded users would have. I wonder how it would perform after 20k miles, 50k, 100k...

I finally got to drive wavetrac on the track- significant improvement vs quaife. It is significantly "smoother" in how the power transitions when you are rotating the car in a corner. The biggest surprise was how the car pulled me around when I put 2 in the dirt. It is easier to drive under poor traction conditions.
As far as daily driving, it doesn't seem to effect it much. Noises are quieter than quaife. It howls a tiny bit when i break 475 lbs torque range on my e85 map but zero slippage or problems of any kind. I got almost 2k miles now at this power level on the diff and it just hooks up at the end of the day...
Hope that helps. This thing is staying in my car...

FWIW, I bought one and its in my car. Its much less aggressive feeling than the Cusco unit I had last summer, but I'm not sure how much more aggressive it is than the stocker, as I made huge changes to the car in the off season.

Yeah, it distributes the power so smooth it isn't the drama queen in the noises and abrupt changes in power distribution like some other diffs. Let me know if you run faster. I think you can go faster with smoother power delivery transitions...

Nothing like that ratchet sound and popping felt thru the steering wheel to let you know its working.
