Dif query,

[mad4slalom]

Out in the mc in the wet and was playing occasionally giving a little gas out of a greasey corner, traction off as that over nannies and stops any spin very quickly, i found that if you back off as soon as the rear slides , the diff snaps the back end back into line quite viciously, anyone else found or have experience of this, would be good to have some low grip track to experiment on , i feel if i didnt come off the gas but continues with some throttle to feed the wheelspin / slide then the diff would allow more slip, is that right ? Anyone with drift/ slide experience ? Mine is the m diff so i guess different to non lsd zeds.

There's a video of this somewhere.....looked like a great road.

I couldnt find it, guess its been taken down.

No experience in this... Isn't the M diff a clutch diff so it's the power that locks it up. Could be just the clutch disengaging when you let of the gas.

Have seen somewhere that the clutches in the diff have a life expectancy of 80000 miles, don't know if that's a fact thou.

Yes the ///M diff has variable lock up and from memory is the clutch type.

The ///M diff does rather snap the car back into line if you rapidly close the throttle, exactly as you describe. One of the tracks I frequently use has a hairpin at the end of a 120mph straight. I've gone into it way too hot on occasion leading to understeer, so used the throttle to pull the back end around. Panic throttle closure in the face of massive high speed oversteer then results in the car snapping back the other way and fishtailing into a tank slapper.
Having tried this unintentionally, I've then deliberately provoked a slide around the same hairpin. It's possible to hold huge oversteer and return to a straight line in a controlled fashion by gently closing the throttle and winding off the steering. Of course, this is much easier if the oversteer is intentional and not unexpected, and when there's plenty of space with safe run off available. I'd recommend finding an empty airfield to practise if you can...

Yes that's right. Be progressive, no sudden throttle movements or it will bite you in the a*** :roll:
