Jim just get the Quaife! The difference is night and day to standard!


I am also interested in the diff, but isn't the Quaife the same as in the focus RS mk1?

I had an RS for 6 years and did enjoy the grip and precision, but really do appreciate the 'less agressive' delivery of power that the
offers.

Does the Quaife change the steering feel at all?

It does give a little bit of torque steer but nothing too bad! What it does deliver though is loads of grip! Ive not really tried it in the bone dry or on track yet but where it would have wheelspun up to 5th gear in slippy conditions it now just gives a bit of spin in first and second! The ESP is working better now too!

I get a bit of torque steer now anyway
just had to concentrate a LOT more in the RS


Its a choice between the diff and the downpipe and sportcat....now thinking the extra power may be useless without the diff


Also, does it affect the weight of the steering i.e. make it heavier at all?

I've just had a Quaife fitted and I had all of your concerns.
There's no need to worry, get it done.

I would say that it improves the steering feel if anything, as for torque steer problems,
it's more a case of vastly improved steering feel and grip. Certainly no wrestling match.

I haven't seen any negative comments from those that have had it fitted, Gary at Profile fitted mine
they have plenty of experience with clutch/diff upgrades. (I would consider the RS clutch as well while it's apart)

You are right in that it's a question of balance, if you enjoy the twisties then the Quaife will
give you a lot more extra speed than the downpipe & cat. I think people shy away from the diff upgrade because it's not
viable to be sold on. If you are going to keep the car its well worth it & the sooner the better I say!
(I concur with Mr. Fishface, in that I find it works really well with the ESP too, despite rumour on the forum that it wouldn't)

I'm not convinced that wider track front wishbones will really help, it's still a McPherson strut with all of it's inherant camber change issues.
It probably aids turn-in and will alter the F-R balance because the roll resistance is changed, therefore it will be very different & most
will tend to perceive a difference as better when they've shelled out a lot of cash for it.

Hope that helps,
Jon

Thanks Jon,

Nice to know about the changes to the diff and certainly food for thought!

As the car has only done 5k miles, i think i might wait for the standard clutch to go before i uprate it although it does make sense to do it if the box is already apart!

Ive not noticed any difference in the weight of the streering although i have noticed that the steering and chassis feel a lot tighter and better connected! I had a full polybush set fitted at the same time though which i would think was the main factor affecting that! The diff has impressed me so much that i would now say that your modding list should be
1 Lowering springs
2 Quaife
3 Any other engine mods
In my opinion a standard car with springs and a diff would run rings round any modded car without a diff in any situation apart from in a straight line! (Even then it would still nail it to second gear!)

Glad to hear im not the only one that thinks the ESP works well with the diff Mr Jon! Ive been surprised just how much difference the diff made despite having had one on me old RS Turbo!


QUOTE(PHILJB @ 15 Dec 2009, 04:57 PM) <{POST_SNAPBACK}>I see they are only an hour away from me, have you used them before Jim?

To be honest Phil i was going to go to CTS (Gearboxman) untill the brakes that i bought came up and i decided that i also wanted the Polybushes fitted! They have a reputation second to none when it comes to fast Ford transmissions! On the other hand Gary and the Wolf gang did a superb job for a great price so i wouldnt hesitate to recommend them also!
