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 🙁
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
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.
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.
