Shuttle Hydraulic Disc Brakes / Wheels

Hi all,

I recently picked up a 2003 Shuttle TXT and have a few questions.

Has anyone done a disc brake setup on a model with hydraulic brakes?

Also, this has the 5:4.5 bolt pattern and I'm having a hell of a time finding anything but the stock steel wheels. I'm looking for a 12"-14" wheel and a 30 series street tire.

Lastly, my F/R switch is funky when going into reverse. I have to yank it over to one side before it engages. The buzzer comes on regardless...but I have to fiddle with it before it will actually engage as shown by the indicator light.

Thanks for the help and I'll start a build thread shortly.
