33" on D2 does anyone have them engineered ?

The tires I ran were 255/85R16, which fit nicely in the stock wheel well and custom flares were not needed, the stock flares covered the tires. I also only needed two to three inches of lift.

I do wonder how the lane changing and brake test mentioned will turn out. Being that the vehicle is designed to tow 7000 lbs, I wonder if the engineers would allow larger tires with reduced or removed towing capacity.

I spoke to Treeve and he seems like a very nice guy and mentioned that he is pretty confident that the car can pass the test otherwise I would not spent the $1500 for both tests.

Changing gears shouldn't affect the speedo on a D2 with ABS. The speed signal comes from the SLABS computer, which gets it's input from the abs sensors, not the transfer case.

Might be worth finding out what brand/model they intend to use. There is a huge number of different units available. However, the D2 uses a strange signal and the vast majority are therefore not compatible. TrueSpeed seems to be the only one easily available to the public that is compatible.

Personally I found it easy to source, install and setup.

Actually, you are correct - my bad. After installing the diff gears I found I had to leave the TrueSpeed still connected.

where did you buy yours from? the details I found on AULRO from a guy in OZ where correct but he does not sell them anymore.

how difficult is the set up?

Easy. It's only four wires - positive power (switched), earth, and two for the speedo signal to ECU.

Then you just drive with a GPS and slowly adjust the dial until the speedo is spot on.

he does not sell them anymore but thanks anyway

happy to report I have my 33" including 100mm track width increase and 5" overall lift engineered now :-)

The one thing that intrigues me here is the speedo issue. ADR state that vehicles manufactured prior to 07 must have a speedo that is plus or minus ten percent, so if bigger tyres bring the vehicle within minus ten percent it should not be an issue.

the speedo can not show slower then you actually driving, when the adjust the speedo it shows now always around 1-2 ks after then I'm actually going
