Lsd's......

[maxi 36 1 Cars]

I have 216BHP and a std mi gearbox with no LSD. This means wheelspin and silly amounts of it. Just been out in the wet and its a waste of time trying to drive normally (light throttle, 3rd gear comes on cam and lights up) let alone flat out. Im running Eagle F1 Tyres.

 

So my question is, what are peoples experiences of different LSD's??? The Quaife ATB slipper seems to be favourite but has anyone had one from another manufacturer thats just a straight forward LSD?? Price is obviously a massive factor.

 

Experiences and advice please!

You can't go wrong with a genuine Quaife ATB LSD for road use. It's fit & forget. Doesn't need any servicing or adjustment. It has it's limitations though which doesn't make it ideal for track work; it won't work if one wheel is off the ground, for example. It's useful to have PAS as well as this acts as a kind of steering damper and stops the car being pulled from side to side as the traction levels of the road surface change.

Don't expect too much. I've a Tran-X and it's terrific in the corners and in the wet but I have very little extra traction off the line in the dry. I suppose if you have enough power to spin the wheels with the 'axle' nearly locked (as even I have) then there is no mechanical technology that can help and you would be better looking at traction control. Maybe the situation is different if you have enough power to spin in a non-standing start situation (as you have) then it's different but I doubt it.

Only one choice for the kind of use you give your car... Quaife...

 

Buy one, job done...

quaife is the only uprated road oriented LSD available to my knowledge, i.e. one that's no maintenance etc.

 

I'm thinking traction control might be a better move, you could upgrade to the DTA 8pro Adam

I have a quaife on mine and it makes so much difference i find even pulling away i have to rev to over 4k for wheels to spin in the wet, and cornering you can put your foot down without leaving smoke behind.

The pulling from side to side isnt to bad and feels like std diff when driving normal

Cambridge motorsport / mass race engine's , they're linked in some way (maybe because they're next door ? ).

 

It's called the phatom grip , got some good reviews

As said, Quaife is not going to help in the straight line if both wheels spin, it helps in corners when the inside wheel is spinning and the torque is transfered to the outer wheel. Either drive more gently or get traction control. You got too much power!

There used to be AP Suretrack which was a ATB diff, Plate types are the serious LSD but require maintenance and not suited to road use.

Good points above

I have an AP Suretrack. There was a post recently which I inserted a link to a Mini page, containing the advantages/disadvantages of most of the market.

Have you come across those Phatom LSD's before Miles?

So it looks like Quaife is the one to go for in road use. Cheers for the points guys, nice to have some actual experience posted for once.

 

Sean, if you knew what I knew, you wouldnt use DTA. Its always up to your mapper and thew guy who did mine ran me through the advantages and disadvantages of most of the systems. For the money, Omex everytime!

Traction control is for housewifes

 

Ive got a quaife ATB in my 309, admitidly it hasnt been used much since i fitted the diff, but after i put the engine in last november it got a bit of testing round the lanes. Driving on muddy, icy/wet roads it gave massive confidence, you just turned the wheel where you wanted the car to go and kept it planted. Put it this way, after driving kates car with throttle bodies, diff and coilovers at haynes a couple of years back, i imediatly bought a diff and coilovers, not throttle bodies.

do you need to take the box off to install the diff? or can it be done in situe?

That's interesting as steve Greenauld also maps all systems around and prefers DTA anyday. As most (not all) ecu's have the same features in the high end clubman spec, it's down to the mapper's preference i've found so far

I've got a Quaife in mine & its fine for road use & occasional trackdays.

 

I can still spin both front wheels in damp oir wet conditions when rolling along in first but I've learn't to be careful with the go pedal in these situations in traffic.

do you need to take the box off to install the diff? or can it be done in situe?

It can be done in situe but its not the easiest way & for the extra messing it involves taking the box off is probably just as quick imo & you also get to check the clutch wear whilst the box is off.

 

You need to remove both driveshafts how ever you do it, there is a guide to swapping the diff here on the main site but this is with the gearbox off the car.

I'd say it is a gearbox of job. I managed to change the diff in situ, but it involved moving the engine, lowering the front subframe and a helluva lot of swearing.

box off it is then

[veloce200 3]

this is one area where modern design has improved things. A friend of mine has an Alfa 156 with a turbo - 200hp - no wheelspin even in the wet - even in first gear - open diff. Agreed a lot more weight on the front but I think that the geometry of the pug suspension is less than ideal for traction.

that's what i noticed about clio sport mk2's... they have amazing traction too!

I've been on track days with clio 172's and they do grip very well.

ATB LSD's will benefit any 205, My engine is standard and it works very well. Doesn't help much for striaght line traction, but on the exit of bends its expectational, in the dry you can feel the torque going to the outside wheel and pulling you round.

 

Only thing to be away of is.. You have more grip true, but when you exeed that grip you have to be careful.

 

Nailing the throttle coming off a wet roundabout will probably spin the inside wheel, but you still hold a line. With a diff you'll light up both wheels and instantly find youself on the other side of the road. Its not an issue if you aware of it, but you'll soon see what i mean.

Thing is being thrown all over the road is part of the fun. My car pulls violently all over the road through the gears. People think Focus RS's have violent torque steer, I didnt think much of them to be honest and they have an ATB.

 

Drove Matts 192BHP mi with the diff and thought it was more than manageable.

Dude,

 

RobSBC may be able to help on this......

Similar horses and setup - with LSD

People slate the RS Focus because that, but they clearly don't understand the benefit of a diff.
