In that case.
The Banjo Diff in the alloy case is stronger than the GT6 derived diffs. It was also the same diff that was fitted to the early Griff 200's. Your car will already be bracketed for an alloy cased banjo and It should have came with one.

The Griff 200s did come with the TVR aluminium cased diffs and the previous owner of my Griff 200 reckoned that it was still fine. I've swapped mine for a Salisbury to be on the safe side but the standard aluminium cased diff should be fine for your avaerage UK 4 cylinder engine. I'm not aware of a limited slip version being available, but if you have enough cash.....Anything's possible ;-)

lloyd.

The alloy casing is a unique TVR bit but it houses the MGB Banjo style diff. LSD's can be had in a variety of ratios and you would be well off talking to some MGA MGB racers to ascertain which works best. You could also talk to Steve reid who has an LSD in his car or Adrian Venn.

For a road car you may like to stay in std trim. unless you know what you are doing an LSD can wreck the rear stability of an early vixen under power on cornering.

Hi just catching up on some of these posts.Nobody has spoken to me about the lsd in my car so they are obviously not interested. For anyone who is I took it out after 100 miles. It was bloody aweful in a road car and slightly better on track if you were screwing the taters off it. I was told by expert who set it up that car a bit light for clutch type set up and if you adjust the ramp angles so its not trying to kill you its not really much use.
Incidentaly I only fitted it for reliability (gets rid of the weakness--the planet gears ) and although my Granny is quite frisky for a road car never felt the need for lsd to control power transfer, prefer the fun of sorting it out myself. Loads more grunt maybe but then car gets unpleasant to drive as road car. Happy New Year.

MGB standard ratio is 3.9 for a banjo axle
Also available 4.1 (rare), 4.3, 4.5. 4.8 most of these have course splines but course and fine xcan be swapped

TranX and Quaife both do LSDs. Plate type better for a light car if it is set up correctly - different ramp angles can make a big difference
