you must consider that the microcasted pistons work much better even with loose fitting..........
a "poor compression" standard piston simply doesn't work while a very loose microcasted piston works very well............
BTW>>> both pistons are CNC machined the same way, the difference is in the casting proccess..........microcasting allows higher silicon content in the alloy which yields better heat expasion combined with ABC contruction sleeve.........
