Limited Slip Differentials

Has anybody on here used one in a Scirocco before? Has anyone driven a modified car with one before?
I understand Quaife make one for the MK2 gearbox..We're talking sort of £650 though.
Having just been out in a mates Fiesta which has a LSD, the ride was mindblowing, I am seriously considering one. Any thoughts?

Not driven a VW with one in but played with a friends 309 Mi16 which he had a Quafe in to begin with, it was good but grabbed at the ruts in the road, he's since upgraded to a Tran-X which seems to be far better at controlling the slipping wheel and less grabby. Great fun on a wet trackday a couple of weeks ago, it just went where i steered!

I've just googled Tran-X and it seems they don't make a VW diff. I'm yet to learn and understand the differences between the types of diffs and bits yet..But I feel the next build may include one.

I've got a Peliquin (I think that's how it's spelt) Imported from the states at around the £500 quid mark when the rest of the conversion was done.
Obviously I wouldn't be without it, if you don't mind a bit of tire squeel it'll pull you in whatever direction you can hold the wheel.

Got a Quaife ATB Diff in my scirocco. Its a awesome bit of kit. only problem is on boost it wants to drag you all over the road. Great in corners though, there is alot more grip thats for sure!
Quaife/Peloquin are the same nearly. Mine was £689 fitted by The Phirm.
My mate has a LSD in his Honda Civic. Said it makes a massive difference on the track, I have not used mine in anger yet.

Wouldnt make much of a difference in a 112bhp car would it? I can see the benefits if your trying to put 150+ through the front wheels of an oul vw but not a standard one?

agree on power as main benefit is putting power down out of corners, experienced quaiffe on VWRs Golf GTI which is pulling well over 300bhp and it was a real gem, you could tell it was there but not intrusive, not cheap though

I'm running around 160bhp at the minute..And it is understeer central. I daren't go near the throttle coming off roundabouts. And early in the new year i'm going for waaayy more power so it seems like a good idea.

I think tyre choice has a lot to do with how the car handles with that sort of power, I know i've got 130bhp at the wheels currently and wasn't having much issue on the road (a damp trackday was slightly different), however having just had to change to a spare set of legal tyres I'm now having problems with lighting up a wheel in 3rd off roundabouts.

I've got around 200bhp and am running a standard close ratio box with no diff and think it's absolutely fine. My old 130bhp GTX had a load of understeer on track, but tbh it's more to do with how you drive.

More used to fast rwd cars, so excuse the ignorance, but does an LSD do much to reduce torque steer in a powerful fwd car?

If anything i would assume it would make it worse ?

my understanding is thast in an FWD car it doesnt reduce torque-steer, thats what your arms are for
instead it allows you to get the power down much earlier out of corners, where the inside wheel would normally spin up when accelerating out of a corner - because the standard diff sends the power down the route of least resistance - instead an FWD drive car WITH a diff sends the power down the route of MOST resistance - ie most grip - so you can keep it planted all the way round the bend with much less understeer, and so a higher exit speed...
but sciroccos are too pretty to drive fast, if you go slow everyone can see you!!
