I've read the instructions, my concern though is that instead of lining up at the zero degree mark its actually 1 or so mm past it.
Hmmm thats strange mine does line up perfectly at the 0 degree mark when it is straight and i did change it so that it had 1 degree toe out which should do.
But still, the problem you are describing is weird are you saying that when the wheels are totally straight it isnt at the 0 mark but still straight?
