I am trying to get some wheels that will fit my new axles, and have some problems finding out if the wheels I need are just an aboration or if this is a common problem when fitting wheels on the waggy d44. The rotors are very big and if you add the caliper into the mix, they measure 13.5 inches or more. I am gonna run 15 inch wheels, and feel it might be neccessary to get wheels with no, or negative backspacing. Anyone know of this and have the measurments of the wheel backspacing they used? Thanks, T.
