Price varies quite a bit - partly depending whether you go Q2 or Quaife - but I've sourced a complete Q2 For 640. Clutch is being changed anyway sc additional labour costs are negligible.

Is that including the 2 x new diff bearings and new driveshaft oil seals & O-rings? If so, good price. Only marginally more expensive than a Quaife.

I thought it was a good price too; one off price, not sure that it could be repeated. Price is for diff and bearings - not sure if it will include oil seals. Looking forward to getting it back and trying it although the downside is that I think I am going to have to have the wife's Abarth remapped as a quid pro quo.

correct decision sir, you are just waiting for the stock diff to go bang TBH if not, and the effect on the handling is awesome, virtually eliminates understeer and torque steer.


keep us posted , however i suspect the next post will be a thumbs up and a big cheesy grin when you can get the power down much sooner coming out of corners ......

Q2 now fitted and other work done. Had the opportunity to dive it a bit and assess the changes brought about by the Q2 diff.

First thoughts were a little disappointing - lost the struggle of controlling the torque steer and feared a less satisfying drive. These initial thoughts almost immediately replaced by the realisation of just how much better the car is. Torque steer is, to all intents and purposes, eliminated and the front end feels more planted and responsive. Traction control will still kick in, but later and before I can get into difficulty.

An expensive upgrade, yes, but a worthwhile one. I now understand why no one tried to dissuade me.

Thank you to all of you who offered advice and encouragement.

I need a new clutch this year and will have either a Q2 or Quaife dif fitted at the same time (on my 156 2.5 V6 SW)... any reasons why I should favour one or the other (Q2 or Quaife)?

I am told (although do not know the truth of it!) that the Quaife is better and generally slightly cheaper.

I went for Q2 because of a preference to keeping as original as possible (a bit daft I know as the limited slip diff was going to be a modification anyway), was able to get a good price, and my local independent doesn't like fitting non Alfa parts!

Apparently the Quiafe is a bit more "grabby" than the Q2.

Oops, what does your specialist do for the parts that Alfa supply, but are made by OEMs ? !

Just did a search of this forum and found this thread which I think answers my question
http://www.alfaowner.com/Forum/alfa-...eef-or-q2.html (Queef or Q2?)

Any other views/opinions still welcome

I have a 3.2 V6 GT with approx 95,000 miles on the clock; when driving aggressively I am aware of some slight clutch slippage so this will need changing in the not too distant future. The car has some wear in the lower suspension arm bushes so the arms need replacing which, I understand, requires the front subframe to be dropped. Whilst this is being done, is it worth biting the bullet and having the clutch changed at the same time? - this also needs, so I am told, the front subframe to be dropped.

If changing the clutch is it worth fitting Q2 at the same time? As I understand it, this significantly improves matters in a GTA or GTV, neither of which have traction control. Now I know traction control limits power whereas Q2 redirects it so the way they work is fundamentally different but how well does Q2 work in the GT with its enhanced electronics?

If I've got any of the above wrong (I am not mechanically minded!) please let me know.
I had Q2 on Jessica (2.0TS but chipped, blueprinted etc to around 200bhp) and it was brilliant. Virtually no torque steer or wheel spin. The power obviously goes straight to the driven wheels where it's the most use.

If you can, do it.

Occasionally 2nd hand Q2s can come up for reasonable money, but otherwise Quaife is the cheaper of the two these days. They both feel pretty much the same to use. Both are fantastic.

Warning!
You will use more fuel as you search out more corners and take a second go round the roundabouts.
Not sure if the latter is legal.

When you are pushing on turn the ASR (traction control) off. It tends to activate before the Q2 and therefore you don't get the best out of the modification and it renders the Q2 pointless. The VDC will still kick in if things get really out of control.

Saving hard to get one on mine. Does the traction control put any extra strain on the original diff when it kicks in? Just wondering weather it's best to keep turning it off or not.

Until I get it sorted any hard acceleration when corning is kept to a minimum.

It's more the lowspeed turns on full lock that will kill it ......

As jwq said, it's full lock that the standard diff doesn't like, as opposed to the drive train shunt resulting from off/on throttle applications.
Mine broke when negotiating a junction.....barely above tick over.....on full lock.

Sorry. Poor phraseology. Local lndependent prefers OEM parts, Alfa or otherwise, over aftermarket parts.
