I am runnig 2 - .9 and 2 - .95 in the buggy with reg shoes that came with the clutch and 8 screws on a xz speed and 2090. I thought it had too much snap still. So I'm going to add more screws to the flywheel. Bit very controllable. I don't like the shoes to slip excessively. I would rather have the engine do the work than the clutch spin hard.
