running 3 alloy shoes and 1.1 mm springs is an agressive clutch set up and it can contribute to more clutch bell and shoe wear

the 5 ports in a buggy are very good and have alot of bottem end power you could try running 2 alloys and fibre choe 1mm springs or 3 carbon shoes this will smooth the clutch out engaging if the springs hangs past just trim it off a small amount it will not cause any trouble doing that ..
