LSD - TRD or Quaife?...

[Ian]

I could not find any discussions of this topic through search. I know that a couple of people have the quaife limited slip differential. I was wondering if anyone has the TRD differential.

I am considering both. But, there is about a $400 difference in price, with actually TRD being cheaper. That price discrepancy concerns me, in that I wonder if the 2 products are different. Horsepowerfreaks.com describes the TRD as a "1.5 way clutch type". I assume Quaife is the same, so why $400 higher than TRD?

Questions:

1. I would like to go the cheaper route with TRD, but do you know if they are the same type of LSD?

2. If anyone knows of, or has heard of experience with this TRD product (or Quaife for that matter) please post what you know, impressions, or whatever.

Thanks

I have a Kaz or however u spell that.. check out www.overboost.com for prices.. its for a 92-95 mr2 turbo
I love it

Thanks.

Edit: Forget what I said, I'll let you read a better more accurate explanation I got off the internet:

Clutch-type limited slip differentials (like TRD & Kaaz):

A clutch-type LSD uses a set of clutch discs, that are connected to each wheel, and the discs are clamped together at a certain pressure when in operation. When one wheel tries to rotate faster than the other wheel, the clutch discs start to slip, the faster disc transfers power to the slower disc through friction, hence transferring power from the faster wheel to the slower wheel.

A clutch-type LSD responds immediately to any slippage, unlike the viscous-type LSD, and is so better from a performance standpoint. A clutch-type LSD is also much more easily upgradeable to handle high horsepower, as the number of clutch discs can be easily increased or the clutch disc sizes can be enlarged. Most aftermarket clutch-type LSDs have larger/more clutch discs. The downside with a clutch-type LSD is that with the slipping of the clutch discs, they eventually wear down and will require maintenance. Also clutch discs will chatter when they are engaged, so a clutch-type LSD is not as quiet as other LSDs.

Clutch-type LSDs are often offered as 1-way, 2-way or 1.5-way. A 1-way LSD only engages the clutch discs only on acceleration, while a 2-way LSD engages the clutch discs on both acceleration and deceleration. If the clutch discs work to limit slip on deceleration, they can optimize traction under braking, but at the same time as they transfer power from the faster wheel to the slower wheel, this increases oversteer in turns. Therefore a 2-way LSD is generally considered more difficult to handle, but superior for handling, while a 1-way LSD is more forgiviing. A 1.5-way LSD is a compromise between a 1-way and 2-way, as it engages the clutch discs with less pressure on deceleration, which allows for more slip on deceleration and hence less oversteer.


Gear-type limited slip differentials (like Quaife):

Finally there are other limited slip differentials that work through gears to limit slip. These LSDs can offer very immediate response like a clutch-type LSD, with little maintenance and quiet operation. However, there are not as easily upgraded for high horsepower as with the clutch-type LSD, they are limited by the strength of their gears. Gear-type LSDs are also generally a lot more costly than the clutch-type or viscous-type LSDs.

I wish i had one for my auto.
But i think Qualife is more expense since it gear type.....

get a phantom grip for auto...i talked to a rep from quaife and they said they would make one for the auto but it would be about 4g unless you coudl get atleast ten people in it to make it the usual price comparable to the manual lsd

Hey I didnt even know that they made LSD's for our cars. That was one disappointing thing that I hated about our cars when I first got mine. Anyway would installing a LSD be hard to do if I did it by myself? Im mechanically incline but ive never done this before.

You probably could do it yourself, but the one thing that you might not be able to do is the backlash.

That is the tutorial from Phantom Grip on how to install their LSD

Hey thanks! But one other quesiton. It looks pretty easy to put in the LSD, but would getting the differential out of the car be hard.
