One other aspect of a LSD on the track is braking, which is way more stable, deeper into the corner with less abs intrusion. But not everybody needs that, big benefit in the race car. Drag car I wouldn't think as important. The quaife LSD in my race car makes driving it easy.

 

exactly. you were good. then you quiffed.

 

This.

Funny how these topics come and go - and come back again. I/Cs, diffs, IPD plenums, brakes... LOL
The one advantage of a Wavetrack over all other Quaife/Torsen/TBD on the market is that it is supposed to provide torque transfer on braking as well as on acceleration. It would be nice if there were an objective, back-to-back test on some of this stuff. Or in the case of a Wavetrack, even someone who's upgraded on the same platform and can provide insights into driving both.

Till then, tho, everyone will have to pay their money and take their chances...

 

After all i will go for a 997 GT2 LSD (25/40% 15 NM preload). I guess that will be good for relatively smooth driving style.

 

I didn't see OS Giken mentioned here, they make fantastic diffs, that aren't quite as expensive as the Porsche stuff but a bit more than Quaif. You will find them in some of the fastest track cars of all kinds around the country. I swear by mine, and have set numerous lap records with it. Installed in 2010 with zero problems to date in a track only car. Just another option.

 

I was told that its not so easy to find the right setup for it. Needs alot of testing.

 

right setup as in what manner?

 

There are so many options that its hard to get a basic setup from OS Giken. Thats what i have heard.
As i said i will go for a 997 GT2 LSD. I dont need more.

 

Rough idea of cost for the 997 GT2 LSD? Is it this one for 3300.00? http://www.championmotorsport.com/product-p/gt-lsd.htm

 

I got another Source. I pay less.

 

I have a used 997 gt2 rs LSD that I’m about to list for sale. Approximately 2k miles, and 1 track day. I got an offer on a GT pro that I couldn’t refuse when I had the engine out to weld coolant fittings. Nothing wrong with the origional LSD, but would recommend new clutches and increased preload as the stock unit in both the gt2 and gt3 is pretty light. Open to offers.

 

I haven't driven one in a 996 but I have personally used OS Giken in my other vehicles and would highly recommend.

 

I've been told the quaife won't take power, it's the casing that is the weak point. Guards has been recommended.

What power are people running on wavetrac?

 

If you haven't opened the transmission up previously and you're looking to set your car up for some hard use, I'd get real LSD like a guard or CUP one. Consider having it set up by an expert who can evaluate the trans internals too and you may be money ahead in the long run. Brian Copans did mine and has worked great for a couple years now, lockup under decel/braking is awesome with a true LSD.
