Which LSD from where?

ALEXARAS - 18/3/10 at 05:16 PM

Hello, I am looking to fit an LSD to my Escort RS2000 powered Locost. It runs about 180bhp and I am going to be using it on track and fast road/uphills.
Which do you suggest?
Who can provide me a good price?

Any suggestions will be appreciated.

what axle do you currently have then?

ALEXARAS - 18/3/10 at 06:02 PM

All running gear is Escort MK2 RS2000.
I think is what you call english axle?
It has got the panar rod and is not irs.
Hope this helps :-)

here you can see a pic of the axle:

As you can appreciate I had a problem with the axle mountings.. Any suggestion on reinforcing them too

I've just fitted a Quaife to my RS2000 axle. It transformed the backend. It moves a lot more now, which is going to take some time to get used to. I'm happy with it so far!

Many thanks for your replies.
Rallydesign appears to be cheaper.
So you would say Quaife is the best option right?
It is good it does not need any maintenance. Reliability is good?
What is the percentage of locking?

Rally design is +vat so they come out at Ł499, Burtons ebay price is Ł449.50 inc vat

The ATB is a fit and forget part, plate types are not

ATB's come with a 1,000,000 mile warrenty, plate types don't

They are a different beast to plate diffs; it doesn't lock as such, rather put the power to the wheel with the most traction

Quaife Differentials
As engine power outputs increase ever further, the ability to use this extra performance becomes more important. Wheelspin may look spectacular, but such loss of traction from either a standing start or exiting a bend wastes time, whether driving on the road, circuit, rally stage or drag strip. Fortunately, QUAIFE's patented Automatic Torque Biasing (ATB) Helical Limited Slip Differential (LSD) is an effective, well-proven, low-cost solution.

Quaife Differentials Brochure

As a direct replacement for the standard, factory-fitted 'open' differential, QUAIFE's differential can transform the performance of any vehicle. Unlike a conventional plate-type limited slip unit, QUAIFE's ATB Helical LSD unit relies on gears rather than clutch plates for its operation.

That means the Quaife differential is much smoother in operation because, unlike a conventional plate-type LSD, the Quaife differential never locks harshly with a set pre-load of wheel slip across the driven axle. Rather, the Quaife differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree.

Sets of floating helical gear pinions mesh to provide the normal-speed differential action. In the event of wheel slip, in the Quaife differential, torque bias is generated by the axial and radial thrusts of the pinions in their pockets. The resultant friction forces enable the Quaife differential to transmit a greater proportion of the torque to the appropriate wheel. The effect is progressive and at no stage does the Quaife differential lock solid, hence the inherent safety and user-friendliness of the QUAIFE ATB Helical LSD differential.

To the driver, especially of a front-wheel drive car, the results of the Quaife differential has significant performance improvements; superior, controllable traction without the harsh steering wheel snatch or torque steer that have long been associated with performance differentials.

These traction benefits can also be utilised in rear-wheel drive vehicles, while QUAIFE ATB Helical LSD differentials offer significant traction advantages when fitted in the front of four-wheel drive cars.

Reliability is total, making the QUAIFE differential a true "fit and forget" solution. All Quaife differentials are designed using the latest CAD techniques and CNC machined to ultra-tight tolerances from high quality Corus steel billets. The completed Quaife differential is then subjected to rigorous in-house inspection with 3D coordinate measuring machines before being dispatched to the customer.

Such quality means that, unlike a conventional plate-type LSD, the QUAIFE differential requires no special maintenance or rebuilds, is long-lasting, and retains the standard method of lubrication, making for an easy, pain-free upgrade.

Proven in rallying, racing and on the road, the QUAIFE differential offers safe, reliable, winning performance - everything you would expect from a QUAIFE product.

i run a tran-x plated diff find it fantastic its noisy as hell but works wonders cost more and need setting up right with the right ramp angles and preload

Many thanks for your replies.
Quaife is the only lsd i had some feedback from a mate who is into escorts. But now that you tell me it works well with locosts and is relieble I am going to be ordering it soon. Will get back with some feedback.
