Hi was thinking of installing one of these whilst re-building the gearbox on my Golf. Is anyone using one of these at the moment and how do they rate it ? / comments. Kind regards
I havnt driven a car wih one in.. (actually thats a lie,i have, just not 'spiritedly' My dad has one in his car, most people tend to say they kill all understeer, dont make the steering any heavier and outright grip off the line is a million times better. No good for competition use though. Edited by: madmk4
traction is greatly increased, you need to alter your driving tho, you don't wanna lift of mid corner (not that you should anyway) as it will snap sideways.
I didn't find off-the-line grip improved at all. Definately a billion times better coming out of bend or off islands though..
Grip around roundabouts in the wet is superb only the slightest bit of understeer if I plant the throttle right down. Not much difference in a straight line. I was told that if you loose traction on one wheel (ie. lifting the inside wheel mid bend) it makes no difference to the standard diff.
I always thought grip "off the line" was their main bonus - just lucky I didn't buy one then. I think I might just weld one of mine up into a spool - should be fun in the multi-storeys......
grip off the line improved when I fitted mine. Before the diff fitted I could spin up all the way through 2nd gear and even a little in 3rd in the dry....pooty falkens After the diff was fitted, same piece of road and same tyres, I could only get a chirp in 2nd gear dirtydubber: it's when you lift the inside wheel that the diff really comes into its own. You would lose all drive with a standard diff whereas the quaife will allow power to the wheel with the grip. When driving hard through a tight bend the diff would weight the steering up a little, but not excessively (I used to run without PAS and it was fine, I later fitted PAS due to laziness). I also noticed I lost a certain amount of self centering, but then again I liked that.
Thanks for all your replies - I have just ordered one ( but havent told the wife) Apart from things like syncros and obvious damage/wear is there anything else worth doing or looking at while the box is apart? ie. mods or things to look out for? many thanks
As I said its only something i heard and can't speak for experience, and i'm not sure that the guy I heard it from actualy has one fitted. I think he may have been trying the slate them cos I have one and he dosn't You are obviously speaking from experience so I'm more likely to bleive you . The reason I said i didn't notice any difference in a straight line is because I never get any wheelspin through the gears, even before the diff. But that is probably just my driving style.
actually dirtydubber is correct. with the gear based torque biasing diffs, both wheels have to be in contact with the floor for it to work. the only diffs i can think of where this is not the case are plate types and i suppose viscous setups. and i also agree that the atb will help with grip off the line. with a standard diff, all the engine power is transfered to whichever wheel is easiest to turn, and the output speed also doubled due to the pinion gearing. with a slip diff you can still get wheelspin, but it would be both wheels !

I have a 24v Vento running an O2A VR6 5 speed, I fitted a 3.94 final drive as I run 18's but I also fitted a Quaife ATB and it is a nice improvement in grip. I have also run a VW Motorsport plated diff with stright cut gears and the improvement over a Quaife is big but that is also why they cost so much money (3,000 for the diff alone!!).
WTF are you on about? ATB diff... not plate diff snap oversteer is lift mid corner induced not ATB diff induced.. Mine have never done this... chassis setup can, but not the ATB diff in my experience. (MK2 Jetta 16v, Ibiza Cupra, MK4 Golf)
It only feels that way becasue you back off in a panic as you're not used to cornering so fast, and the only reason the back end steps out is due to lift off oversteer BECAUSE you're going so fast. Keep your foot planted and just steer through it.
