Atlas LSD Info
Just after a bit of advise regarding LSDs.
I'm looking to upgrade my F27 atlas axle with an LSD.
Looking online there are lots of options, I'm just a little unsure what the pros/cons etc are.
I have found the following two options. Can anyone tell me the difference, apart from the obvious price differential?
Thanks,
Liam

Let me tell you what I did as I find diff's a bit of a black art.
I went to my local rally expert axle under my arm, he fitted me a 2nd hand plate type diff, (reconditioned by him) set it all up (the black art bit to
me) to suit from his experience a lightweight car that's been used on Tarmac, it transformed the car, no under steer for less than the cheapest
diff you linked above.

It really depends what your using the car for. If it's a race car or track only then a well setup plate diff is hard to beat. If mainly a road
car I would be looking at the second type which is more an ATB (automatic torque bias) as the plate diffs can be a bit aggressive and noisy. The
plate diffs will also need maintaining at set intervals.
The ATBS are great in my experience. Good on road and track and they need no set up or special servicing, just fit and forget. They don't lock
up as aggressively at the plate diffs, much more progressive. If you decide on an ATB type then the quaife unit is the one to go for in my
experience. I have no experience of the rally design one tho.

the rally design atb clone is made in china, ive never seen one or fitted one but we all know what the reputation of things coming from china is.
crossflow distributors where the skew gear eats the camshaft, injectors that fail after half an hour and ruin your engine, bosch 044 fuel pumps etc
etc.
even the proper atbs suffer from wear, most people never take one to pieces as they beleive they are fit and forget, true they dont need plates
replacing but you'd be surprised what happens to the gears inside
plate diffs are great and if you are careful and select the right type in the correct configuaration for your intended useage then it should do
everything you want. plates only need replacing after extreme use, in a road car you'd probably only need a shim or two to bring back up to
spec

Thanks for the replies so far.
I've found the following on ebay:
Atlas LSD, geared type to suit 16 spline standard half shafts Capri Escort TR-81
What are peoples thoughts?
The car will predominantly be used on the road, with occasional track use.
If I were to purchase the above, is it essentially take the old diff out and fit the new one? Are there any other parts that should be
changed/replaced/serviced when the diff is out?
Thanks,
Liam
