WaveTrac Differential?
 

I'm in need of a differential and I'm looking at what options are available out there.

Anyone has any experience with this brand of differential? WaveTrac Differential.

The price for this one new is $1,295.00

Another one I came across is the KAAZ G50 Limited Slip Differentials $1,695.00

Porsche 911 G50 Quaife ATB Helical LSD Differential $1866.77

I've never used a Wavetrac in a Porsche but I had one in my 240SX and it worked great. It was the ideal LSD for the street and track use.

KAAZ is a clutch plate design so it'll be the most aggressive locking but also will require maintenance. I would use this one if you are serious about track days but it's not the best for the street.

Quaife is a great street diff as well and wont need any maintenance.

I'm currently running a Wavetrac but have less than a year with it and only one AX event. Seems to work well so far.

thank you guys!

I doubt any guys here are putting their diffs through the torture you are Juan! Wouldn't Eddie be the best person to ask or is he in 997 land now?!

Further inspection revealed that the ring and pinion is what appears to be bad, I'll know more once we open the gear box.

Quaif is too weak for what you are planning on using it for. They were very popular for a while in racing but they fail sometimes in high HP applications so a lot of people were swtching over to guard. I know Eddie was using a guard diff and also gear sets. But thats been two years now since we were all at that car show together. A Guard is way more expensive but pretty much idestructible.

Arrrg, I just bought a quaif Ken. How high is "high HP"? I suspect that I won't be near that territory but since you mention it I'm curious. Also no plans on drag racing but the turbo'd 993 I built is an absolute tire burner - ONE tire!

LOL, I went from burning one tire to a burned clutch with the Wavetrac.

Not sure what the hp they considered high but it was a lot of cars that were being tracked both drag racing and road racing. I looked into it in about 06 when i was still putting my car together the first time. Someone here or on rennlist had seen a lot of them come into their shop broken and were upgrading to a guard. So i looked into getting a guard and it was out of my price range. and every time since i have considered getting one the price has went up more always keeping it just out of my reach.

Eddie continues to run one of our differentials but in all fairness he runs a spool so it's durability would not be a fair indication of our LSD's strength holding capacity.

What would be more representative would be the numerous cars built by the likes of Evoms, Champion, 9ff, Ruf Germany and many many others who have out them in 800-1200 whp cars.

Like the other companies mentioned we do also make a torque biasing gear driven differential. I don't recommend putting them into cars that are over 500 whp.

I can't speak to the strength of anyone else's TBD but the weak link on a TBD is the planetary gears and none of the others mentioned make gears that are larger than ours. Draw your own conclusions about what you think they can take.

I purchased Guard Transmission in July of 2009. At the time the MSRP on the GT3 club was $2795 and the GT2 Pro $3095. Those prices are exactly the same today.

Thanks, Matt.
Always a fair honest answer.
I always enjoy your posts. :)

Still out of reach for me unfortunately and last time i looked at it was i think before 09 but not positive. I thought i had the engine out just last summer but i have been spending so much time at work working weekends etc. it's actually been 3 years So if by any chance if you have a clearance or scratch and dent sale please send me an e mail. Last time i was at the track it was pretty clear to me i needed one. So when i get it back together with EFI i'm sure it will be even more of an issue. I guess i need to stop spending as much money on hot looking slutty chicks and save more for the car.

So if by any chance if you have a clearance or scratch and dent sale please send me an e mail

Sign me up for that!! :D I even take a second class citizen discount! :D:D

As we speak, I just ordered a Guard replacement clutch pack for my factory ZF limited slip diff.
I've been assured that it is a nice upgrade over the stock ZF internals, hopefully the parts will arrive on Friday?
But since my ZF limited slip has been operating as an open diff for a couple of months, anything will be an improvment!

Well you may laugh but i got a really nice engine crossbrace from rennline like that

I had a 40/65 Gripper configured around 70 ft/lbs fitted to my 915 and loved it. The single best mod I made to the car.

So no going back to open diff for me. But Gripper don't list a unit for the G50.

I didn't even consider TBD's; decel lockup when you back off is a truly wonderful thing.

I researched everything I could find about the Wavetrac, KAAZ and OS Gikken LSDs, including reviews, comparisons, track testing & timings, and experiences folks had with them in all applications. There's a lot out there.

I just did not get the warm fuzzy feelings that I was hoping for.

In comparison, opinions of the GT were very consistent.

Discussed it with Matt and ordered a GT configured the same as my previous LSD. I'm very happy with it so far.

I've got a WaveTrac installed in my 3.2 turbo and have nothing but positive comments regarding street and track use!

Sign me up as well :-)

Group buy?
