R32 Gtr Front Diff Torque

[PAV34]

Hi all,

Ive noticed today the the gauge that shows the Front Diff Torque has started to move during normal straight line driving and the more i put my foot down the higher the gauge will go.

Usually the gauge only moved when i turned a corner quick i think, but never during straight line driving.

Which one is normal!

Cheers.

I think i may have found the answer to my own question.

Is it because I have 17" wheel all round and the tyres i have are 255/40 on the rear and 235/45 at the front?

I recently changed wheels and these were the tyres that came with it.

Does this have a negative effect at all?

Also, the car came with a torque split controller...

Yes it does affect it as the rolling diameter is different

[PAV34]

But it couldnt stuff up the diff or anything could it?

sure could - the transfer case is not meant to run all the time. start with same sized tyres all round

too rite...make sure ur rolling diameter is the same on all 4 wheels

[bnr#@]

Definitely get same rolling diameter tires front and rear, otherwise one set of wheels are technically trying to travel a greater distance then the other set of wheels, the attesa thinks you have slip and engages 4wd, doing so constantly overheats and wears out the clutch plates in the transfer case

[PAV34]

What if i made it 2wd for the time being?

that would be fine but be carefull..i only have a gts4 and in rwd its quite fun so i could only imagune what a gtr in rwd would be like

[PAV34]

Righty-o

I have flicked the 2wd switch, and the 4WD & ABS light comes on, does that mean no ABS?

[GTS4WD]

Yes.. You will loose ABS

in the fuse box in the engine bay.. on the left as you open up the bonnet.. the fise said something like ANTI/4WD/PTC.. or of the sorts.. its the first green fuse in the row of small fuses towards the center of the thengine bay.. This way you wont loose abs..

u can run the larger diameter wheels at the rear and smaller ones at the front n shouldnt affect the gauge moving, dont know if that would render it the same reaction times with same size diameter tyres when attessa kicks in tho.

[Yawn]

You can run different sized tyres front and rear as long as the rolling diameter is the same (or close to). An example of this would be something like 265/35/18 and 235/40/18, if my maths is correct.

No good to run the car on 2wd for too long with just the fuse pulled out too. If you want to do it rwd, take out the transfer case too.
