The increase in drive train wear on my buggy is because the foams are harder than mini pins. The shock of hitting a rumble at speed is sent straight to the out drives. The 'give' in mini pins/spikes dampens this. It's certainly not grip related.
The fluff was really bad on wednesday evening. The worst I've seen it. It was wrapping around one of my driveshaft and a clump was collecting on the rear bumper each race. The average power of the buggies at Mansfield has increased over the last year, it seems new pins are needed to keep them under control. It goes against the 'slow is smooth, smooth is fast' ethos.
Steve's experience with pins vs foams is spot on. Foams are slower but more consistent and I for one can't justify the cost of replacing tyres every week to remain competitive.
Maybe limiting motors to 13.5 or 10.5 blinky is the way to go to ensure longevity of the carpet?
