||Been using this for quite some time now on my truggy. D8t, .21xz, .28xz, with 2060/2090 pipes, 13t/14t vented bells.
Noted interesting thing, clutch nut isn't a normal sized nut, clutch shoes look like they would get shredded quickly and would lack punch.
First things noted on the track (.28xz w/2060 pipe), power delivery felt smooth, bottom end punch was fine. Acceleration out of turns weren't difficult to control on both
high and low traction areas. After a couple of hours of practice runs, the shoes had very little signs of wear at all, tension springs had no signs of
fatigue, but the thing intrigued me the most was the fact that the clutch bell bearings I was using felt as though they weren't used at all.
Long term notes, shoes changed at about every 4th gallon of fuel, large shim disappears after several tanks of fuel, clutch bearings just have to be cleaned, repacked
Other notes, clutch shoes are quite expensive per unit but last pretty long. Maintenance is minimal. Replacement shoes are hard to find anywhere.
No more filing down mushroomed shoes anymore.
