Agree with the above, and I've told Micky this before.
Thanks 911Micky, what he's saying here has nothing to do with ease of changing the"severity" of the LSD action. He's just saying he builds them out of BMW bits, and that he can set it up for serious competition, or much less aggressive for road use with occasional track days.
So you won't be doing easy changes of plates in the LSD before and after trackdays, as I said above.
He's saying he can build it to your requirements, so either a soft action for the road, or a very hard action for the track. You can't have both, changing the action, means removing the diff and changing the number of plates inside, every time .
Also bear in mind that plate type LSD's wear out quite quickly.
A ZF LSD typically used in historic cars such as Escorts, Opel Manta's, Ascona's, Kadetts, Hillman Avengers Alfa's etc will typically last 5000 miles in competition, and they begin to lose their effectiveness in about 15000 miles of road driving . The friction surface on the plates wear out.
After that they need a rebuild to restore the effectiveness of the limiting factor.
Ask any owner of a 105 series Alfa 2000 GTV, they all came with a ZF type LSD as standard.
The plate type LSD's are all adjustable for effectiveness, the common ZF types are set for the road at 25%, by inserting more plates, you can get 75% effectiveness.
In my experience, having had both, you wouldn't want to use a 75% lsd on the road. I've attached an exploded view of a typical Drexler diff, that is constructed very similar to the ZF and Salisbury type "clutch plate" mechanically operated ones.

Hi thereMicky, if it is a plate type diff, it is of course adjustable, but only by taking the diff out, stripping it, and either adding, or removing plates to make it more or less aggressive in action.
I Whatsapped the question:-That means nothing without an explanation to you whether that setting is for occasional track use (and also good for the road without being too harsh), or otherwise Micky. Did they elaborate ?
Hi SteveWhat was the main reason for switching to the Drexler from the Quaife?
You may have explained it already, but I was probably still at junior school back then
Thanks SeanOne thing that will knock seconds off your lap times is a bit of professional instruction.
When I did my first ever track day at a very wet Castle Combe I managed to grab a 15 min session with an instructor.
Couldn’t believe how he shaved around 5 or 6 seconds off my lap by explaining how to drive properly.
Could be worth thinking about Micky boy if you want to extract everything your project car will one day offer.
I just found this post on a car forum from someone who has installed a Drexler and is reporting back with some feedback.Thanks Sean
I fully intend to have some track instruction on the UP GTI as I want to explore the potential to the max. On the road i am probably an average driver.
I am quite excited to see what the "pros"think of the car!
