Limited Slippy

Does anyone have any experience of these:

Seems a good price for a potentially very effective upgrade.

How would it interact with the EDL already on the car? Would it just mean the EDL wouldn't cut in?

EDL shouldn't kick in, because both wheels will be turning the same

 

[yell_oh]

Would it give any benefit over the EDL?

As far as I understand it, the EDL brakes a spinning wheel to cause torque to be diverted via the open diff to the wheel with grip.

What I don't know is whether the EDL works in a proportional way, i.e. modulating the braking force until the spinning wheel finds grip, or whether it's just a clumsy on/off method.

The Quaife would seem to proportion the torque to exactly match the grip ratio of the two driven wheels.

I think a mod like this in a FWD car could potentially give more of a performance boost than upping the power with a chip. My old RWD BMW was less powerful than my FR, but I could cover ground much quicker as I could use all the power, whereas the FR just spins it away in smoke. Any improvement in traction would be a big advantage.

EDL is only active sub 15mph, but as you suspect it's on/off braking of the faster wheel

but will torque steer

The price is good , but then have to pull out the eng/gboxdiff £XXX x dismantling the gboxdiff £xxxx x assembly of gboxdiff £xxx x refit into engine bay total cost around £2 - 2.5k.
I have fitted diffs when I had FIAT ABARTHS for hill climb/sprint work, its a long clean and precise work not a job for the average diy

I wouldn't say it was as much as that...

the 02Q looks easier / no harder than the 02M to remove from the Leon - and Diff fitting normally costs ~ £600 inc g/box oil

Interesting technical article on LSDs, EDL etc.

According to the last paragraph, the Quaife and EDL complement each other nicely and should *reduce* torque steer in FWD applications.

I've been told it'll cost slightly more to fit than a new clutch.

i had a clutch n diff fitted for 500 quid on an 02m 6 spd , it feels 100% , not that much torque steer ( you know its there tho) definatley is worth the money if you have issues with grip

Fabia vRS here, got a Quaife and it is definitely and unreservedly recommended if you want to get that power down on the road

Much easier to control power, more mechanical ability to drive out of corners/control slides/avoid them
