Tranx vs. Quaife

[Craig]

Hi list,

 

I have been running a Tran-x limited slip for over 30 years. It's been a great product. I am now looking to change my diff to a different rear gear ratio and would like just to setup another diff.

 

The question is what is the difference between a TranX and Quaife and which would be better for competition.

 

Thanks,

TranX as it's a plate type rather than an ATB

Indeed - Quaife is a torque biasing diff rather than a limited slip diff.

The ZF is supposedly superior to the TranX though - something to do with the metals used giving a smoother locking action on the ZF (or so they say ). There's also the new Titan LSD, which is supposedly no better than the ZF, but cheaper and more easily obtained.

Concensus is the LSDs are better for competition use - especially when kerb hopping is involved as the torque biasing diff will let a lifted wheel spin-up. An LSD will stop this.

As far as I know, Caterham have always supplied LSDs with their race cars (well, when the cars are allowed trick diffs anyway).
