Quaife ATB Limited Slip Differential

[Elanlover]

The Quaife automatic torque biasing (ATB) helical gear limited slip differential (LSD) is a direct replacement for the Elan's factory ‘open’ unit. This LSD is fully automatic and progressive in operation and unlike plate style units the Quaife ATB never locks, but seamlessly and smooth transfers power and torque away from a spinning wheel to the wheel enjoying the most traction. In practice this significantly reduces torque steer, understeer and steering ‘snatch’ in front wheel drive applications compared to a plate style limited slip differential.

Definitely not cheap but more than a few Elan owners have installed this and liked the changes it provides over the stock unit. More information and ordering can be found here. Group buys occasionally pop up when more than few people are interested in an effort to reduce the price.

A superb piece of kit. Personally recommended.

I have one fitted. It struggles to control Torque Steer on my car if steering not straight under hard acceleration, I do have 270 bhp though.

I presume its a major job to have one fitted?

What - it can't cope with a piddling 2/3 power hike?!? Right, I'm definitely not having one then!

I would be interested if a group buy happens to come along.
