Differentials available for Testarossa / 512

I have, via my Local Ferrari Independent garage been put on to a suppler of differentials made specially for the Testarossa / 512 / 365 that they highly recommend.

I talked to the manufacturer last Friday. The differentials are complete except for bearings. That is to say, they include the internal gears and limited slip clutches. The supplier will set up the clutch as required, e.g. as normal for the road right up to full race settings.
The diff casings are bolted together so no welds to give way and the walls of the diff are thicker than the standard so much stronger in every way as far as I can see.
This differential is used in both road cars and racing Testarossa over here in Europe so its pretty well recommended. All that is needed is to fit the bearing, install in the gearbox and shim as per the manual.

Both Mel and I are going to put an order in for a unit each in the next couple of days, there is a 6 week delivery.

The cost is is £900 and may be less. I read the paperwork as £750 so I am waiting for final confirmation tomorrow. I will let you know as soon as I get the confirmation.

If anyone else is interested in adding to the order please let me know.

I think this diff also fits the 365BB.

Not until mine arrives. I will post up the installation when I get the job done

The UK diff is made from EN24 BILLET steel and fully NC machined, not cast at all! I have the engineering and manufacturing drawings.
The diff comes complete with new (readily available) internal gears and clutches. The limited slip diff used cams and so is variable while driving from slip under little or no power/turning to being almost locked under full power or one wheel being light. The LSD can, unlike the standard Testarossa / 512 diff, be set to you own liking before fitting.

Ago that is just what the Diff available in the UK is. Based on a racing 512M but set up for normal road use and semi affordable.

I'm afraid I have no idea about a Torsen diff but I do know all the internals are readily available in the UK, I recall the supplier mentioned Jaguar and GT40 parts.
The supplier has promised me he will provide photos before "The new year"
I will post as soon as available.

I'm on to it first thing tomorrow morning Mel. At least he knows he has a large order already and I will be pushing him for an early delivery as well

I got some photos of a similar diff, this one is for an Alfa.
No photos of the TR / BB version as I am waiting on them making some for me.

There are no promises but you may well get yours through production a little earlier as you are in (desperate) need.

Okay, there is now clarification on the price here in the UK.

The complete diff, ready to drop in with only shimming needed, is £850 .
Complete with all new internal gears and LSD clutch plates etc.

Fit, shim and drive
Shipping to the US is not expensive and the diff comes with a Lifetime Warranty apart from fair wear and tear!
Now that must be good!
