mine came with a .3mm thin and a 1.0mm thick, the first time i set it i just took out the .3mm and it was better but still jerky on take off. the last time i took out the 1.0mm and used the .3mm , if yours is measuring 1.5" i would take out the thick one and be done with it, only problem is it might squeal a little when idling in gear. the .6 or .8 would probably be perfect but i couldnt find one in town.
