i called last week about the true track M78 centre but was not given a answer whether it is made for M78 Diff? they had M80 i think but the are to suit another diff..

Summit Racing has some good prices.
Any body know which would suit Au2 Xr8

i just put a tru trak in my fg xr6 it's awsome it cost $1400 but well worth it i fitted it my self they didn't make a exact diff center for my car but a vz ss center is the same deck hight it's quiet and hooks up hard it's like a locka with out the tyre scrubbing i recomend it and if your in the sydney area i could recomend some 1 who can get you 1 + fit it

Harrop have a trutrac listed for Ba-FG.

This probably wouldn't suit Au though.

yeh i need it for an XH.....same as au yeh? changed at ba?

I'd like one for an ED XR6 LSD. What would i be looking for?? Part number/brand/place to buy in Sydney? What sort of prices am i looking at for it? I'll get it fitted at work

not shure on the part number but probly around $1400 with bearings look on the harrop web site and send them a email

Really, that sort of price? Bugger

Compare that to how much you pay for an LSD rebuild and the lifespan/effectiveness....depends what you intend to use the car for really.

they're helical so they last ages and they're quiet they're almost like a locker not cheap but a s**t load better then any of the OEM crap

The write upon Lokka's I did a while back...

gearbox-suspension-brake-driveline-f4/locka-4wd-diffs-t88690.html?hilit=lokka

Pics and all..

When these were first bought out to suit the Borgwarner I am told yes they were noisy... Now there is revised springs and this is supposed to have quietened them down... Mine is second hand but has the new springs... When I get it in one day I'll let you know though...

They are distributed by 4wdsystems as they are common in 4wd diffs because they will never let a wheel over speed... un like an LSD or SS diff they allow the outside wheel to over speed (for the sake of cornering) and drive the inside wheel...

These drive the outside wheel and let the inner wheel under speed (so the description goes)... So they let wheels underspeed but never overspeed... hence it is impossible to spin one wheel...

Hence the 4wd application... Reduces the chances of getting bogged dramatically...

Cornering off the gas would be like driving a normal car (slight ratchetting noise apparently) and cronering under gas would be like driving a v8supercar with a locked diff... Should pull you out of the corner very nicely...

anyway its all written in those posts I made linked above...

Yes, in reference to the post above mine I was saying compare the cost of rebuilding a s**t standard lsd to buying your preffered method of true trak/lokka/detroit and unless it is purely a daily driver you are much better off spending the extra $$$.

Hi All...

Fitted my Lokka yesterday... Either I can't drive or there is a very precise knack to these things?

Most things aren't a worry... The noise is louder than I expected, actually feels quite embarrassing like something is really wrong with your car, its very prominent... The feel is great... Its just this dealing with the backlash that's interesting...

Your rolling into a corner in second (manual) and hit the apex where you would begin to accelerate normally and as you apply the accelerator a few things happen:

1) you have heaps of backlash to take up
2) the wheel that is ratcheting changes... So you have the inner wheel ratcheting on the way in and once you start to drive (even the smallest amount) it then drives the inner wheel and ratchets the outside wheel... This basically adds backlash...

So I can't find a way of going around a corner in second and trying to accelerate part way through the corner... It ends up and a massive jerking mess as the Lokka tries to work out which wheel its driving... Somebody fill me on how your supposed to drive these things like this?

Looking at Matt's post back at the start of the topic...

I'm guessing yours Matt is much like the 4wddrive systems lokka which is shown here:



On that powertrax note, that richmond place does another type... Supposed to be ratchet free and has basically a different set up of springs and that:



I'm wondering whether these work the same way... They write that these are supposed to be more mild for daily use and still fit into a SS centre, unlike a true trak which requires someone in the know to put them in (set up the diff again)...

May send them an email and ask them what the go is...

What model is the Borgwarner diff exactly? I've seen it labelled as LR68, LR69 and M78 so I'm confused as to exactly what model diff was in the ED...

At the end of day not really stoked with the Lokka... Fine for track use... For navigating round abouts... I can't quite get it smooth...

Cheers,
Tim

Seeing as everybody has jumped with feedback...

I thought I'd post up another inspiring photo I found of them on ebay... I still can't work out how it is they work... But anyway... Please see the attached...

Cheers,
Tim
