Hi guys,

I am currently changing my clutch and putting a quaife diff in my car, I was quite surprised by the words of warnings I got from the garage yesterday.
They were telling me that :
- track days were out of the question, that I would destroy my diff
- I shouldn't put slick tires on
- the diff was something fragile that needed extra attention in order to make it last.
- this was a gentlemen driver's upgrade that would be usable only in the twisties

Now, from what I could read in all the posts I could find, I thought that this torsen diff was an install and forget part and that it was rock solid?
Also is it that bad to track the car with it? This is the main reason why I got it in the first place so this bothers me a lot!

I'm looking for (long time) quaife user feedbacks and also track enthusiast opinions because what the garage told me was so different than what I expected.

Who on earth is fitting it for you? Sounds like they don't even know what it does. Having an LSD transforms the car. It might wonder over tracks in the road a little but i couldn't name one negative thing about mine. The way the car turns in and holds itself in a corner is so much better. You won't regret it.

Not got one in my Mini but having had one in my mk1 Focus RS, mk2 Focus RS and Megane r26 all of which having covrrre plenty of hard road and track miles they are are great bit of kit.

Fit and forget items :)

As others have said, find another garage that know what they are doing and what they are talking about..... or sell it to me for a bargain price :)

You don't know the Hell I went through just to find a garage that was willing to install this LSD, most garages (in Switzerland at least) do not want to fiddle with the internals, they are just scared that they can be held responsible for any kind of trouble that can happens later.
All they want now is to remove a fully assembled part, trash the whole thing without checking what went wrong and replace it with a new assembly.
This garage was reluctant at first, after a long talk I could persuade them to contact a specialist to do the LSD part.

Today I am just wondering where I can find the rare old school mechanics that are competent and proud of their work...

a) your garage are confusing the Quaife with a plate type diff

b) take the car to the garage for them to remove and hand to you the gearbox. then take it to a gearbox specialist for the diff to be installed with new side bearings and correctly set up, then return the box to the garage with nothing said.

Quaife is the best drivetrain upgrade out there. Mine has 20k miles. No noises. No vibrations. Only grip. And less tyre wear. ?

I know how you feel. My "independent" is refusing to install the brake pads I provided, and yet at the same time they are advising me to have my calipers completely rebuilt. There's nothing wrong with the calipers. They just want to issue a huge bill for a simple disc and pad swap. I'm going elsewhere.

yep, did just that so I guess I will be gone with them as soon as I get my keys back!

Refusing to install brake pads... what is wrong with the generation of mechanics today?

This reminds me of the time I asked the dealership to fit my bucket seat on the driver side (I had to make them do it for administrative reasons), they returned me the car and their comment was: "we're never doing that again, this was much more work than expected and we are not used to doing that special kind of requests, it was a one time favor." - the supervisor of the garage.
I was stunned in disbelief.

Well my car is finally back from the garage but my joy was short lived as it will return there monday... :(
LSD was installed, valeo kit installed, but the clutch pedal acts weid and sticks to the floor!
It feels worse when the car is cold I think?
After a few minutes of driving the pedal feels better but still "lazy", like sticking midway and finally coming back up.
It is especially bad if I reverse the car out of my alley and then try to shift to 1st, the pedal stays to the floor and can't get the gears to change, I have to pull it up with my foot and even that is not enough to disengage the clutch sometimes...
There are times where the clutch is fully pressed and disengaged but I can feel the traction coming back when I'm in reverse, just as if I was slowly lifting my foot from the clutch ?!? WTF!? At that point my only option is to cut power and wrestle the gears into neutral to stop going in reverse.
That last weird behavior is especially scary and could not find a definite answer to this issue.

Did anyone of you experience something similar?
I read about master/slave cylinder (slave was changed) and possible air bubbles, if you can help me point a probable cause it would help me a lot!
