Morning all

Winter job number one is to get my LSD rebuilt for my 997.1 GT3

Can anyone recommend someone to do this in the South please?

Preferably somewhere I can take the car and leave it with them (I dont have the space or time to remove the LSD myself)

Kind regards
Kul

Edited to add - Spoke to JZM, they can only get the parts from a supplier in the US at considerable cost!

997 GT3 diff?

Remove from car,attach to chain, use for preventing boat drifting when fishing. It may however not prove useful even for that.

Seriously, take the opportunity to put in a proper diff and never look back. Its 20/40 lock up and cheap as cheap can be. Look for a used 996 GT3 diff if you don't want to spend on a guard unit or similar.

Had my 996 GT3 LSD rebuilt with cup plates by JZM. Top job! Took them a morning while I had a couple of lovely cups of coffee and a browse round the used cars. Easy.......

A proper diff is the plan. Looking to get a ramp of around 40/60. Do you know where I can get a guards unit from in the UK?

Yeah, they were my first choice but they can't get the parts anymore! They have to source them from GT Gears in the US at considerable cost.

I am looking to spend around £1500 all in. The parts that JZM source blow my budget frown

It might be worth speaking to Hartech - they had some diffs custom made for the Boxster race cars and also the 996 race car, I think they could be set up to suit your requirements too.

I think you're going to struggle to get a complete diff to the correct spec, fitted, within your budget.

As a rough guide, a set of Cup plates and fitting on my 996 GT3 diff was approx £1000. Not sure you'd be able to get a full diff assembly with Cup plates, fitted, for £500 more.

A quick search on EBay and a used 996 diff is $1800 and that doesn't even have cup plates in it.

I had new Cup plates fitted to my 7.1GT3 by RPM Technik last year, cost about £1500 all in. I had an oil change done same time and total bill was just over 1700, but I think I supplied the oil... My before-after 'testing' / comparison was at Silverstone, and the difference was night and day. Much better with the new diff, far more stable when applying power out of corners.

Spoke to Ken at Nine Excellence and he thinks he may be able to get me a guards unit built within my budget, he is going to check and get back to me.

Email Matt at GT Gears (guard) and find out what your options are and what will suit etc.
Then you will atleast have an idea to take to whoever will do your work. You can then just work out whether they order the parts or you do.
His diff knowledge is incredible and he's a really nice guy.

Sites not letting me add to my above post:

Given your budget, I'd expect you will only be able to replace your plates. The factory ramps will probably have to remain. How far from optimal this is will depend on your use.
Fwiw, labour for a diff is essentially fixed so it may make sense to apply man maths. Either justify the ramps at the same time or hold off until you can do both (providing you want them).
Regardless, shoot an email off and you should get some good info back.
