Re: Q2 diff, whats the crack?

The stock diff in the V6 and 2.4 10V gearboxes are the achilles heel of the drivetrain and are reguarly dismantling themselves and throwing the pin out THROUGH the diff case, locking the gears up and destroying gearboxes, for around £900 (or less wink,wink) you can have a Q2 diff fitted, this is the Torque Sensing type diff which sends power to the wheel with the MOST grip (NOT like an LSD which restricts the free spin of the loose wheel), this reduces understeer to a near impossibilty and makes the car handle like it's on rails, the only downside is that I'm away for a couple of weeks soon and if you want one you'll have to wait till I return for much cheapness.

£900?? The part is under £350 and if you're changing the clutch then fitting shouldn't be any extra.

£900 is Autolussos quoted price, of corse I would easily beat that.

Re: Q2 diff, whats the crack?

Wanted to have it fitted to the 147, Jamie Porter of Alfaworkshops advised fitting it to the GTV 3.0 ( £ 480 fitted , if you need a new clutch do the two together ) , it has totally transformed the car, corners much flatter and allows warp speed cornering, on a car that was great to start with ! Absolutely Fantastic. All the best, Safe & happy Motoring.

There's not much point a TS has so little power that it will make virtually no difference

Re: Q2 diff, whats the crack?

Is a Q2 diff recognisable from outside the car? I know the mod should be advised to the insurers, but would a loss adjuster recognise it for what it is?

No - nothing visible but an interesting question. A performance enhancement that encourages more enthusiastic driving but one that actually makes it safer to drive.

Re: Q2 diff, whats the crack?

If it only makes a few quid differnce to the premium that's Ok, but with my Ragazzon exhaust being fitted on the 8th, saving up for the Eibachs/Konis before summer I can just envisage the insurers saying 'enough is enough' if I go for a Q2. Very tempting though. Hope my clutch goes soon!

Get the Q2 done. Totally changes the way the big heavy diesel engined Alfa handles....and V6's obviously. Lewis at Alfatecnico in Mansfield did mine for £500

Re: Q2 diff, whats the crack?

Guiliasuper, See you fitted your gtv with a Q2. Has this affected the tourqe steer to any degree. I read on MotorAuthority.com - Car news, reviews, spy shots and videos that it was not recommended for cars with macpherson strut suspension as it causes excessive tourqe steer. Any feed back welcome. ATB V6ER

Re: Q2 diff, whats the crack?

£900 ain't AutoLussos price, they charge £480 inc VAT, for the lot, thats new seals, gbox oil etc, for club members on here. Otherwise its £500.

Cheapest price I know from an official garage, although as the price off the diff and shim kit, seals, bearing, from Alfa, comes to about £300, plus some more gearbox oil, I don't think its a bad price at all. I watched AL's mechanic doing mine and I'm glad I wasn't doing it on my drive..

Re: Q2 diff, whats the crack?

I would like to clear something up, i would completly agree that my
Q2 system makes cornering amazing ( the more power you feed the wheels the more grip you seem to get !!!) however !!!!! and this is a big However, when spending this sort of money you need to know that
I have the 170Bhp Cloverleaf and from standing the Q2 system dose noting to stop wheel spin or torque steer which I was rearly dissapointed about !!!!! its a big decision, If ur anywhere near Mansfield drop me a line and I'll take you for a spin, see what you think, good luck

Re: Q2 diff, whats the crack?

On our V6 GT it's made a massive difference to traction, especially in the wet. As Alfa's have double wishbone suspension, the fitment it generally unobtrusive but when the road is excessively rough, cambered or rutted, it can become a little bit frisky when giving it beans in lower gears.

While the car was being" revived " at Alfaworkshop I had the misfortune to have a Hungarian truck lose the plot on the M.11 at @ 50mph in 3rd the GTV just spun it's wheels whilst the trailer headed in our direction, dropped it into 6th and we just avoided disaster.(before fitting Q2). Have found no noticeable increase in tourque steer since fitting Q2. In dead ahead you can still induce it, but backing off a tad and then booting it solves the problem, as pre Q2. As stated above the Q2 makes huge improvements in cornering stability and therefore speed. Hope this answers your question.
All the best.
ps. check the engine topmount .. ours was in several bits.. when I replaced it tourque steer practically vanished.

I agree, can be pretty scary on wet, dark, bumpy roads.. Massive fun though.
