Anybody running this combo? Pros an cons? Have a Lwb. Will be putting chromos in front with a WT diff. Would there be any advantages with a NT rear? I know the new landrcuiser utes run a wider front then rear.

I remember seeing this mentioned a few times but can't find anything.

[Gwagensteve]

AJSR has done it and his car regularly seems to drive the impossible. I'm sure the NT rear is the reason why

No real disadvantage at all as far as I can see - some excellent advantages too - it will keep the rear end up out of the ruts a bit more.

Suziblu thought it would suck on sand.

[sogone]

Win. I'm gonna do it. Have a complete WT rear here with NT perches ready to go so if it sucks balls I'll just change it

[sogone]

And now that you mention it my old NT 1 liter on all terrains tin top went much further in mud then my twin Locked WT, muddies and g16b due to it not sitting in big ruts that pole smokers in there landbarges and 37's have tried to dig to china in.

[Fatzook]

I've just finished a customers car with WT full RUF, and extra NT rear spacing on Feroza springs. Rear is inboarded a further 30mm per side in the rear.

Should have great flex!

Its running 33x10's on -40 rims, with only 2" suspension and 2" BL. Wheelbase is close to 90".

Hows the thing corner on-road?

[Gwagensteve]

Slowly....



Boom-Tish

I'm sure it will be fine, just sooooft


I reckon Piggles was better in mud with just a rear locker on 1.0 diffs than it was WT/WT locked both ends, because the car sat up on the crown of the ruts.

It sucked everywhere else though.

Don't know yet. But the lucky owner lives 2 streets from Glasshouse entrance track, so I'm sure he'll manage the long drive to the local tracks

[just_cruizin]

NT's only benefit I can see is the ruts and even then the 3" isn't enough a lot of the time to ensure you're out of them. To say an unlocked Nt out drives a dual locked Wt will come down to people's perception of things over time. Generally the obstacles driven these days is a lot harder then what the same person would have years ago. How many people can remember seeing a gnarly track when the first got into wheeling and thinking nothing would ever get up/over/through and now they drive through it unlocked just to through to something that's really fun to drive

[sogone]

I agree jus_cruisin. However this was a real world test where I got stuck in the WT and I had to get my NT unlocked past it, Through black mud on the side of the track past the WT to pull it out. So I can happily say that I feel my NT out performs the WT twin locked in that situation.

[Gwagensteve]

I understand your point just_cruzin, but "perception" doesn't come into it. On the day I drove a particular hole NT/open front, I outperformed twin locked WT cars the same day. It was 100% because the car rode up on the crown of the rut under the mud. WT's sat in the bottom of the rut and diffed out. This happened often enough for everyone to notice. The instability of my VERY narrow NT setup made me want to go WT, but I couldn't argue with it in mud.

Whilst 3" isn't much, 3" of tyre diameter or 3" of tyre width is a lot. 3" of track is enough to make a difference if you are just clinging to the inside edges of the crown.

I subsequently significantly increased my track width with the same size tyre (WT diffs, wider, flipped rims) and whilst the car was much more stable, it started spending a lot more time in the ruts and dragging the (bigger) diffs.

That's the #1 reason we're running Krawlers down here. The width of the tyre allows a similar inside edge width as a stock NT but the overall width of a WT on 8" rims, so we get the best of both worlds in ruts. It's a enough of a difference for us to build whole cars to run them, and give up significant directional control when out of the ruts.

I'm sure AJSR will chime in - it makes a noticeable difference to his car running NT rear.

In any case, there's no significant disadvantage, so there's no loss to try it.

Steve.

This is what im about to do to mine, just going through shaving and bracing the housing and setting up some better spring mounts like gwagen has done before

[anDy86]

I was all ready to give this one a crack and got a bit concerned about the legal side of things.

Would be so much easier on my LWB as buying a NT rear would bolt up to my original spacing and also the tailshaft. All that would have been needed is to find another 3.9 centre for the front.

Is it really noticeable having an 75 ml width on each side? Does anyone have pictures?

[2stroker]

Fatzook that one you are talking about, am I right in saying it has RUF + WT diffs front and rear with WT spring spacing at front and NT spring spacing (+ some) at rear. If so that supercharged blue LWB that used to be around had that and it worked awesome (it didn't have feroza springs and norrower than NT spacing at rear)

And

What the others are talking about is actually running a WT diff in the front and a NT diff in the rear

I just saw this 5min ago in another thread

viewtopic.php?p=611885#p611885

[2stroker]

No Jazzor that is not what they are talking about, what they mean is does it stand out like dogs balls when you are driving around with a WT diff in the front and a NT diff in the rear

[anDy86]

I guess if i have matching flares front and rear and wider mudflaps to cover the width it might be right?

It's only 75mm overall.

BTW 'ml' is a volume measure

[pyrohamish]

unless its mils...in which case it is a lengths

[got_bar_work]

mm is length

A friend of mine has a GU tray back with a leaf rear, the back diff is substantially narrower than the front and boy did it suck on sand until he started playing with rims and tyres.

I love my NT width, it's gotten me places I know I couldn't have gone with WT diffs.

[sogone]

We don't have sand here. If that's the only concern traction wise then I'll do it this weekend.

That sounds to me like the one miles built years ago. I'm pretty sure this one was a swb with a ute chop and Pete ha extended it.

[2stroker]

No it was a NT LWB with wide track diffs, rear spacing changed to NT on the diffs, front spacing changed to WT on the chassis, not sure if Myles had a hand in it but it belonged to Roxie at some stage and then to Pete then it was wrecked out, the body and cage have now found their way back together and it is being built into a offroad racer at the moment.

[OFFROAD_SOLUTIONS]

Where the front shackles reversed ? The one I'm thinking off was

[2stroker]

No mate it was the blue supercharged LWB one that is all over utube

[BlueSuzy]

a lot of Toyota diffs are narrower in the rear.

My bundy rear is 30mm narrower track than my lux front.

Yes. I assumed we were discussing spring spacing, not mis-matched diffs. Thats just crazy.

I'll go see the optometrist now.

I think the bundy front diff might also be 30mm narrower than a leaf spring hilux diff.


I am not sure about WT's but on LJ's and NT's the rear diff is actually 1cm wider than the front (I don't know why)

[2stroker]

I just looked it up, the Bundera and Hilux are very close:

Bundera track - 1425mmm front and 1420mm rear

Hilux leaf sprung track - 1420mm front and 1400mm rear
