Quaife ATB LSD - Anyone fitted one yet?

[geeeman]

i would agree with the posts above, espec damien.. I have had a Quaife in the past on a race car, and id did have great grip using r888s. But as you say the TVR has alot of power

So are Kaaz Diff available to fit into a cerb?

The Last time i inquired about Kaaz, they were Australian distributor only, as its a Holden part.
May have changed?

I used to share the building next to Driftworks , hence I knew of the Ozzy only Holden diff.

I'm probably being over optimistic then on sourcing the Holden diff.

Have a go!
It was 3 years ago I tried, and my modded cone diff is doing its job, lts only the odd time it gets overwhelmed, eg slick tyres when putting the full 620lbs/ft down, it occasionally spins up!

And when on a rolling road the car shouldnt be brake tested on rollers, ask for a decelerometer to be used instead.

Hello not heard this on before please tell me more?

Not just for ATB, but applies to all LSDs - should be decelerometer tested (and is confirmed in the MOT manual) to avoid excessive heat/wear and risk of skipping off the rollers.

Worth being aware that, even if you have a car that comes with LSD as standard, it won't be automatically flagged on the tester's system (and is one reason I usually wait with my cars).

Quaife Diff was my first upgrade on a Cerb Sp6, which I arranged before picking up the car (which broke down 26h after purchase - AC pulley fell off!). Had seen too many videos of spinning cerbs even without much provocation, so bought for safety and handling. Not much time with the diff yet, but can report that standing start traction is good, tiny wriggle and off she flies. Anything that gives confidence in the wet has to be worthwhile. Check out fitting prices though - can be pricey.

5 year thread bump.....

I have a tuscan which handles pretty well (imo) however while a lot complain about the front end i don't like the back so much. I can only describe the back as feeling a bit disconnected. On smooth warm roads where theres plenty of heat in the tyres it feels good but obviously that's rare. instead it drives like i feel the back may need correcting at any moment! it doesn't inspire confidence, although i will say when the back does let go its easy to correct.

i also get quite a shunt noticeable most when changing from 3rd to 4th gear at the red line, this induces some opposite lock which im sure you'll agree at those speeds is scary.

1st gear you can't put really all the power down as it spins up, 2nd it spins up only gripping properly as speed increases.

Reading these posts makes me think a quaife diff would be a huge difference?

Have you had the geo done? How old are the tyres? What model Tuscan is it - 4.0, 3.6, S? Was the Hydratrak LSD an option on the Tuscan or standard? Somebody swapped a Hydratrak for a Quaife as part of a 4.3 upgrade in a Tamora in the last year. Can't remember who though. If I recall they said it made the car feel a bit more rough but driving was fine.

Sounds like you may want to look at the throttle set up as well if yours is so lively all the time.

Its a long story which i will try and compress......

First of all ill say i haven't used the car for about 2.5 years and in the last 4 or so cant have done more than 3-400 miles have had lots of other commitments until recently when i thought 'ill get it back on the road! "

As you can imagine its got a load of bits and pieces needing doing so im wanting to sort it as well as i can!

red rose tuscan, gaz monos, rack raised, different off set wheels which are lighter with federal 595rsr tyres and several geo set ups which eventually resulted in a car which was actually quite good. especially on smooth warm roads. The diff is a 3.73 normal btr diff.
down a b road it wasn't too bad but i can only say the rear feels a bit detached, like it might catch you out and sometimes it almost has.

part of the issue may be the tyres, on a warm road the car is a lot better,infact on hot tarmac in italy i couldn't even provoke the car to get sideways! i think that these and the ad08 i had before just dont get enough heat in them to work well. i will be putting a road based tyre on like a ps4 once back up and running so maybe some improvement.

i am re doing the bushes and plan to take the car to centre gravity to have them set the car up properly i am hoping that with some slight adjustment to my geo settings i liked and their magic it will be good.

I run [road certified] medium compound trackday tyres on the Wedge but I also do trackdays. If I didn't do trackdays I would run quality road tyres. Both the T cars run Uniroyal Rainsport 3 and I have had no issues during 'spirited' road driving.
