Is the Quaife torque biasing differential worth it??

I Googled the hell out of it but cant find any real reviews on it

This looser didn't get any response on the same question: http://forums.corvetteforum.com/c6-t...y-got-one.html

If I remember correctly, which is a rare thing these days, the guys who used them on the strip talked about a weird feel from the rearend as it hunted back and forth from one side to the other to maintain traction.

ALL of the fastest cars have them,

AtomicFusion, and countless others.... we install at least one a week now. They work very well and have a very smooth transition...

Just had an RPM quaife diff installed in my '02Z about 750 miles ago. No complaints from me. Doesnt seem to have the grabby, jerky feeling when doing tight radius turns in the parking lot like my old DTE diff had.

Me likey likey.

Does your car hook up better with it although I guess you are still in the break in period?

Funny you mention that, because I've driven a car with a Quaife differential. It was a modified 335i BMW making around 400 rwhp, and it had that weird, unstable feeling under hard acceleration. The back end would feel like it wanted to sway from side to side. Not 100% sure, but I think the owner installed stiffer M3 subframe bushings in the back and it cured the problem. Not sure if it was a Quaife thing or just a power thing.

I've had no problems so far with mine (about 1700 miles)

Earlier today I was on the phone to a couple of places back east checking on what it would cost to have my DTE Stage 4 diff upgraded to a 3.73 ration and also include the Quaife at the same time. It seems to me that I found the mention of the weird feeling of the rear end in the C5 section regarding drag racing launch.

I notice no difference in straight line performance.

That's the kind of info we need.....first hand experience.

Yes! If you make power, you need this piece. End of discussion.

07MontRedcp

Okay Ed, I'll order tomorrow.

BJK,

Ohh you bastage! =)

That was said for effect! Yes, all of the fast guys/big power guys have 'em.

I've run them in both of my forced induction C6Z's. Must have piece my friend.

Got ya

I do like it, and no clutches to deal with. It's not really any faster but it does improve control putting power down. It's hard to describe, with less side to side wiggle and more grip and go.

I installed a Quaife LSD in my Street/track 05 with a Doug Rippie oil cooler this summer.
It seems to work great on track and street. I hear some gear whine on the road with the windows up. Has anyone else experanced gear whine with the Quaife?

DOUG @ ECS

Go figure, we have had a handful of the regular racers at our Corvette challenge events install them with no luck what so ever? Not install problems/gears etc, and built in different locations, but shafts breaking, gears wearing out inside the carrier, that sort of thing.
We have switched to the Eaton carriers and have not looked back.

I got my DTE Stage 4 back yesterday. I had the Quaife and a 3.73 ring and pinion installed. I have a lot of other things that I'm finishing up also, so it will probably be after the holidays before I will be able to road test everything.

Which one of the DR Rippie oil coolers did you install and what did you thing the kit. Any pictures of the install?

Most likely the quaife is not the noise culprit. The differential gear is much more likely to make noise. We haven't ever had an instance with a quaife making noise.
