Thread: 33" on D2 does anyone have them engineered ?

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.
