Stuff... the ATB is on a par, if not better than electronic traction control!
.. I think we can quite categorically say it is not better than traction control.. maybe contact the nissan GTR development team and let them into this secret.

I cant find the line which says its better than traction control.. ETA - one of the forums linked to this site:

Can't really compare to TC esp not with power you boys have hell you could weld the diff and still spin up the wheels.
The plate diff and viscous type should lock the rear axel (stops inside wheel spinning too much) and is great for power slides.
The ATB doesn't lock but continually distributes torque to the wheel with most grip (it's cog based but I don't understand it invented by audi for the Quattro iirc) so in a turn you can make it slide with too much power and in the straight you feel the torque move as the tyres struggle for grip which feels a bit weird if I'm honest.
The ATB or normal diff allows you to apply more power and get it to the road but you still need finesse to go quick unlike TC which will censor you inputs. That's not tvr IMHO.
The ATB is a little better than the other types but only a little better having driven the same car with both types.

Well, we drove up to Coventry yesterday morning and handed the Tam over to Dom at Powers Performance. Sorting my throttle bodies, changing the air/fuel sensor thingie, Anderson connector, and - when it arrives, my new diff.
I say when it arrives because when I got back home yesterday, the guy that's installing the Quaife into the diff was trying to ring me all morning. The Quaife doesn't fit - I was sent the wrong one! The diff was meant to be delivered to Dom today and installed, along with new poly bushes, CV gaiters and speedo transducer, and I was meant to pick up my car tomorrow - but I don't think that'll be happening now.
The diff specialist is now liaising with Quaife to try and get the right ATB LSD, so it will hopefully be sorted soon - although god knows how much it'll cost me in the end...
I think that, when I get the car back, and it runs as well as I am hoping it will, I'm not touching it again this year - just gonna enjoy it...Been too obsessed with upgrading the car instead of driving and enjoying it..
The last time I saw Dom was almost a decade ago - he hasn't changed one bit!

Hope it all goes well, you should have left the car for a week and had the 4.3 put save you keep going backwards and forwards
I have just left TVR Power as new 330 mm discs and carbone Loraine pads squealing a bit so had shims put they seem to have worked
Dom has got his men well trained, they said ooh Gary you really need to get the rear brakes upgraded and carbone Loraine pads put in so they balance out and it just so happens with have just got new grooved rear discs delivered today
That's it another £300-400 spent
Must remind myself to stay away from TVR garages

No 4.3 upgrade yet. After totting up what I've spent on upgrades alone during the past 10 months of ownership, it already comes to over £12K!
I cannot spend the same again in such short time, wife would kill me.
Will wait a few months and then secretly book it in for a 'special service'...
The saga continues.
It appears that I bought the wrong LSD. I bought the Quaife ATB for a 1997-2005 BTR-M76 hydratrack diff - but it transpires that the reconditioned hydratrack diff I bought to house the Quaife is in fact a Morgan Aero 8 Mk3+ / TVR Sagaris / TVR Tuscan 2 BTR-M80 Hydratrak diff - 2005 onwards!
The new Quaife should arrive tomorrow morning at the specialists, and then sent off to Powers Performance in the afternoon. I hope....

OK, Just been informed that my diff is all ready and is on its way to Dom now!
Had to buy another Quaife LSD, so this has cost a pretty penny - hope I can return the original LSD. If not, it will be for sale...
The actual cost of fitting the Quaife, including 2 new bearings, was less than £200.

Picked my car up this morning, and am now home, after yet another drive in torrential rain!
The diff does work! I tried it out (the limits) a couple of times in the wet (and no other cars around) - pulling out of junctions at nearly full throttle with zero drama. You can still get the wheels to spin, but the rear stays more stable than before, without a doubt.
Oh, and the throttle body refurb with new gaskets make the engine run a lot smoother, too. Although, as usual, it all cost almost twice as much as I initially anticipated....
I did have some extras, though, a new jump start plug, thermistor, lambda earth mod (no idea what that is..), new diff poly bushes and CV boots (supplied by me), and air temp sensor.
ETA - the old diff looks like some old relic exhumed from the deep!

Glad its all sorted though and your pleased with it and it cost you less than you thought, well that is what your wife has been told 
T350 is booked in with Dom for its first 6000 miles service, I am having to rest her for a while as I am off to Normandy the week before the service and need to keep the miles down so thought I would get the miss / flat spot sorted on the Griff and not at Doms thought too far for me just to get flat spot sorted, boy will I eat my words, I did take it somewhere else previously they changed all the electrics , air flow meter and phoned all fixed great I thought and picked up drove 100 yards still the same, had a few words and response was "what do you want me to do about it" thought I would best leave it there and took it to Taylor TVR turns out to be a worn camshaft, so I thought sod it got a couple of quotes and Griff is booked in with Dom, told you I would eat my words, as luck would have it I can drop off Griff after T350 service
I have decided to get Dom a credit card save me messing around
Lucky I have a Cerb as well or I would be completely TVR less

I have really spent too much on this car in the 10 months I've had it. Enough now, my wife has been more than understanding, regarding my addiction. I shall now sort out our living room and get a multi fuel log burner before winter...
I too have took the Tam to other TVR places and been bitterly disappointed - I guess, although expensive, you know what you're getting with Dom (big bill guaranteed, too....)
Oh, I feel I must also 'big-up' the guy who installed the Quaife into my diff. He was great throughout and helped sort my problem without charging me any more for the time and effort.
He go me the correct Quaife LSD for over £100 cheaper than the original one I bought (that was £816), he charged less than £200 for installing it and then personally drove to Dom's to deliver it. Top bloke - Central Axle Services (Midlands) Ltd, in Birmingham.

Lambda earth mod is essentially earthing each of the 2 earths on each lambda to a better earth on the engine rather than relying on the earth point through the loom. Thats what dies on mine, killed the lambdas and would have taken the cats too if they were fitted. mine starts and idles from cold better than it ever did and thats without re-balancing the throttles, just providing a better earth!The diff does work!

Thanks for that explanation, Andrew So that's where some of that (just under) £1600 bill went, then...
Still have a prob with my speed sensor, I didn't have it changed in case it was just a dirty sensor at the diff end. Although pretty glad I didn't, hate to think how much extra that would have cost!
ETA - Look at the state of that!
Gotta clean it up and sell it now, try and recoup some money...

It's only done 30k miles, BTW.
Received your fantastic Sagaris bible yesterday, great stuff.
Didn't realise the diff weighs in at 36kg! No wonder I struggled carrying it across one field to another when I bought one at Burghley. Nearly killed me!
Over 10kg more than a complete K-Series VVC head!
