I have the maxtorque six-shoe clutch with the stock shoes. I installed the black spring, and now the shoes are too light for the spring. I'd like to try some heavier shoes ( I know what some of the opinions are going to be, but I've done some research and what I've read is that heavy shoes and a heavy spring are the best way to tune a clutch for smooth engagement across the powerband, so I'm not asking for opinions, just where to get the shoes). I've checked affordable gokarts, but they are out of stock on the wedge shoes (surprise, surprise). So if anyone knows where I can find the wedge shoes (looked a lot of other sites too, no one has them) or a way to make my current shoes heavier, that would be great. I saw this weight kit: :: Be Tram Motor Sports :: but dont know if it will work on my clutch, as to my knowledge there is nowhere on the shoes to bolt the weights to. If anyone can help, its much appreciated.
