Which LSD?
Hi guys,
i want to install a LSD, so i can get rid of the AWD for Drift events and for the road race track.
I want to install quaife. The 997 Cup/GT2/3 or such are maintenance intensive.
Anyone uses this quaife LSD?

Cheers

Subscribed, I’m interested to hear peoples experience with this. The awd on these card doesn’t seem great and restricts rear tyre choices. I have 12.5” wide rears but can only use 315 tyres! I’m thinking, get rid of awd and put a good lsd and maybe 355 rear rubber?

They are not...simple misinformation.. A good quality properly set up LSD is nearly bulletproof with virtually no required maintenance. A Quife or other gear diffs are not LSDs. They are TBDs (torque bias diff) with no ability to fully lock. Different animals.

On a quaife if you lift a wheel = no torque, you loose the torque to the other wheel also. Vs limited slip where the wheels are essentially locked together with a limited amount of slip allowed between them, even if one is off the ground

Thx. Understood.
So for drifting and a little road racing the quaife should suit my needs.
Seems to work quite nicely.

The quaife is cheap compaired to the other mentioned LSD like 997 Cup et cetera.
As far as i understood they are all LSD just the technic to achieve it is different (Plates/Gears).
Since you can leave the transmission in the car, the swop should be done in a couple of hours.

For street use though a simple wavetrac would be sufficient? I can't recall a time in my ownership where i've lifted a wheel canyon carving or spirited backroad driving? I get for hitting rumble strips at a track or something but there is a significant price difference between a wavetrac and a proper LSD (1kish vs. 5kish?)?

it is not being properly installed if doing it that fast. lot of measurements and tolerances need to be checked/re-checked, need new bearings and re-shim it, it is not a take one out, put new one in kind of job unless you don't care about your gearset.

My personal experience with torque biasing diff vs true LSD on a high power street driven car (ran 9s at 150+ mph) is not with this platform, but what I noticed is that torque bias diff, the car tended to gently fishtail left to right to left to right when tires broke loose, where the clutch type LSD i replaced it with made the car track straight when tires spinning. I assume the side to side motion came from how the torque bias diff functions with sending power back and forth to whichever side has more grip where as the clutch type diff locks it. I didn't realize how unstable it was until I changed it. Don't know if same will translate to this platform. Maybe the diff in that car was failing, maybe Porsche behave different, maybe wavetrac torque biasing is better than an OEM (lol) torque biasing. There are differences, drive both and see if it is worth the money. I can tell the difference from driving with one diff to the other in acceleration, braking, but I never really drove that car hard on corners with the torque bias diff.
For me I look at like this: one works as it should most of the time, one works as it should all of the time. I don't personally know any road course guys, even casual track day guys that spend most time on street, running the wavetrac style diffs in these cars. And some cars that come from factory with torque biasing diffs switch to clutch type diffs for consistency as i mention above.

lifetime warrenty and able to handle 1000 hp to the wheels. its been used for yrs on corvettes bmw m/b mustang and others for both road and drag duty. for the street you will barely notice its there. i have one in mine took 2 hrs 2 shims and a new bearing on the d/s havent looked back. rwd with a tbd is the mack daddy! like a porsche should be
it willl allow you to "drift" and "throttle steer" your car while running rwd in ways that are just not possible with the awd setup. all for 1200 bucks with a lifetime guarantee, and no plates to ever need replacing.
at the very least, it is worth further investigation if your attempting to go rwd and do not want to end up being ONE wheel drive lol. trans does need to be dropped to re-shim and set the lash spec.
it will totally transfom the car.
add: it does NOT allow or contribute to "fishtail or "tailwag" under extreme braking. in my experience.
