Anyone had their LSD rebuilt?

Thanks to Porsche4life, it looks like my LSD is shot! Anyone had theirs rebuilt? If so, by whom and how much?

My BMW diff was rebuilt as mentioned for £200, that included a change of ratio.

I think the diff unit is very similar to the ZF range of LSD's so if you can source the parts (new plates and conical washers) and hopefully all the bearings are OK it should be similar.

I know Gantspeed can do diffs and i would expect any independant who also races to be able to do them quickly and efficiently.

I bought a Quaife unit for my C2 and it was installed by Gantspeed, they noticed one or two of the bearings had pit marks on them. The diff unit is not particularly clever... very old technology.

Sorry for the bad news.... cannot wait to see you back out again though..

It's around £500 for a rebuild kit. I'll probably go for that. The LSD has zero preload left in it.

Yes, rebuilt at 26,000 miles on 996 GT3 Mk 2 by Manthey Racing for just around Euro 1,000 using Cup parts (apparently more durable).

Kind regards

Exactly, get replacement parts from Porsche motorsport rather than regular parts dept, you may never need to look at it again.....the price difference is negligible if any.

If there's hardly any price difference, why don't they fit it as standard then?

Maybe because they can make a litte more noise as the diff works and perhaps could be a little harsh for your average luxury porsche owner? More likely they assumed the originals were strong enough for the average use the car would get?

It is 10+ years old now, standard 993 diff plates are a known weakness on the model.

As I am sure you know, the motorsport dept don't exactly have a set price list and parts can have a different price from one month to the next, this also goes for availability.

My price diff quote was based on me spending about £60 more for motorsport version, which made a big difference to the car once fitted.

Just idle curiousity here but how can you tell that the diff plates are wearing out? Does the diff shunt get progressively worse as you slow down?
