ATB FITTING
It’s one of the best upgrades you can make to a modern fast Ford, so let’s see exactly what’s involved with fitting a Quaife ATB differential…
What's involved with installing a Quaife ATB diff?
If you read our feature last issue looking at how an Automatic Torque Biasing diff transforms the handling of a fast Ford – especially cars like the new Mk8 Fiesta ST and the four-wheeldrive Mk3 Focus RS – then you’ll no doubt want one fitted to your car. If you haven’t read the August issue, then grab a copy to see what key members of the Ford Performance team, Jamal Hameedi and Leo Roeks, and Michael Quaife of Quaife Engineering have to say about the performance advantages an ATB differential can bring to a fast Ford.
We’re pretty sure you’ll be convinced. In fact, we’re so confident you’ll want to fit a Quaife ATB that we’ve gone a step further and teamed up with the guys at mountune to show you exactly what’s involved with having one fitted. The Mk3 Focus RS may have missed out on having an ATB fitted at the factory, but thankfully you can at least have one retro-fitted. And if you have the work done at mountune HQ or any mountune-approved Ford dealer, it doesn’t affect the vehicle’s base warranty.
The benefits are well publicised, and after driving an RS Edition model (which does come with an ATB as standard) we were totally converted. We needed one on our own RS. But it’s not just RS owners that can benefit from an ATB upgrade – any fast Focus or Fiesta owner should consider one.
But enough of the reasons to fit one, what’s actually involved with installing an ATB? Well, quite a lot as it turns out. It’s definitely a job best left to the experts! To show exactly what’s involved we shadowed the technicians at mountune as they installed a Quaife ATB to our very own Focus RS. Here’s just what the upgrade involves…
