Quaife ATB Differential – reloaded

[frenk]

The Focus RS Edition seems to come with the Quaife LSB already installed. There has been some rave around pertaining to a better handling and traction in corners, although with poor persuasion and mixed ideas.

I was fancying an upgrade this year and so I asked my Ford dealer for retrofitting the Quaife LSD into my 2016 RS. The answer was quite sobering.

First, the price in Switzerland is CHF 2,750 (£ 2,070) all included.

Second, they fitted it on the same vehicle that I have (may 2016). The effect was negligible and unperceivable on the road. So the verdict is: a complete waste of time and money. It seems to be a placebo and marketing effect 🙁

Any opinions, folks?

@Frenk the benefits of the lsd are for track use, although traction out of slow speed turns, especially in the wet should be improved for fast road work.

It makes a marked noticeable difference and the Ford UK dealer I used or Mountune UK cost for supply and fit is / was £1401.

Mine is also being fitted in a couple of weeks and having a ptu brace fitted at the same time so should be intresting to see the difference .  I went to the autosport show last weekend and had a chat with the guys at quaiffe and it appears the car wasvways ment to have a LSD but someone at ford America didn’t sign it off so it was deleted . They also said that ford has ordered hundreds of LSD so that proves it is a good mod to do

Right…, different opposing views around. I’ve done 50,000 km on roads so far, nil on tracks. So I postpone this LSD project and wait for more convincing data 😎

Did anyone do the Quaife Diff install on the Focus RS on their own?
I plan to do mine over the weekend and I was wandering if I need to also change the bearings and some sealings I have seen in some other videos.

If anybody has some feedback, anything is appreciated as it will be too late to decide/order when the gearbox will be open.

Having mine fitted at the same time as the HG waranty work is carried out. Been quoted 1400 to supply and fit

[white-rs2]

Its not worth losing your warranty to save a couple of hundred £ and loosing the whole weekend to do it. As fitting it yourself blows your warranty.

The Diff, The Fitting kit and The Labour averages at around £1400 done and dusted.

They don’t know how to do that here in Romania in Ford service I think lol

They wouldn’t know about it anyway in case of warranty need.

My car was in for motor change (cracked block) and after that I did a decat myself – the stock cat pipe was welded to the mounts because they had broken some bolts/nuts  – I know for sure I will never go to this service for anything except mandatory oil changes.

 

The real question was if I can fit the diff without the Mountune differential fitting kit as it was not in stock when I got my PO.
