Looking to possibly fit L.S.D in my new project car to be used for 1/4 mile and odd trackday not everyday use , is anybody using one either clutch type or quaife for such use , any personal experience would be grateful ie has improved times out weighed high cost of such item .

Thanks pete.

One advantage is that they are much stronger - and share the loads out over both drive shafts. From years back experience in Rallying etc - I would say it's a MUST for you!

ive got one on my mini, its waiting for clean roads before it goes on the road, but i couldnt resist driving it in the snow!! it helped a great deal!!

I would say if it was a 100% track car then a plate type diff would be the right choice. If wanted for any road use I'd go for the quaife ATB.

My plate diff made a massive diference on my hillclimber, but it's not exactly a relaxing drive!

I run a Salisbury and while its great fun on the road its also lethal, but I wouldnt change it

Agree with above, plate type are great on the track, my trannex is superb.

ATB for the road but they are terrible on track, i had one in the racer before the trannex and hated it.

I am looking to keep car road legal so to drive to the strip/circuit and to take out for a blast now and then , how is the drive is it harder to turn in or torque steer wildly ?.
My main aim at the moment is to reduce wheelspin and beat 1/4 mile times set with current car , at the same time as not wanting to buy into something that would be a total pig to drive or encourage ditch hopping !.
Thanks pete .

Salisbury has incredible torque steer on anything but perfect flat tarmac, but, the turn in and grip is just amazing, so much so that the first time I took a passenger out after fitting it I took a roundabout spiritedly and he fell out of his seat and onto my lap - funniest thing ever.
The ATB is supposedly the best compromise of street and track but Ive not driven one myself.

i think the torque steer will depend on the ramp angles surley? usualy dictates the visciousness etc

also the drive shafts will have an effect of drivability, apparently hardy splicers give a feel of twitching side to side as they rotate

Sorry for highjacking this thread.

I recently could acquire a Salisbury lsd incl. two Hardy Spicer output shafts for a quite decent money of €400 incl. postage over here.

 

In one of my rod-change gearboxes I run a Tran-X lsd and I am quite happy with this. Now I read in DV's 'How To...." that the Salisbury will not fit into a rod change box. Why should a Salisbury go into a remote box but not into a rod change?

 

Did anyone try to put the Salisbury (which is a little bigger than the Tran-X) into a rod change box?

 

Kind regards,

Helmut

Long time ago now, but I fitted one. There was some minor case fettling needed like for most alternative diffs going in to any case.

[r.tec]

Thanks Spider. Glad to read your answer. I have some spare gearboxes so I'll give it a try myself. And yes, even for the Tran-X I had to modify the case slightly.

[Gaz66]

I just fitted a tran X to a rod case and there was minor fettling compared to the Salisbury I fitted before that.
You will probably find you break through the casting into a bolt hole for the output shaft cover but just apply plenty of thread lock to that bolt to seal it or you'll get an oil drip.

For the road, I found it down right dangerous, couldn't take it out fast enough. Yes, you need to 'drive ' them, but being on the road isn't the same as a track, things come up that need a fast response that can't always be 'driven' in to. I'm very happy with an ATB thanks !
