Lip seal or 'O' ring..........what do you use???
I'm told the 'O' ring is more driver friendly due to out of round rotors that cause the pistons to move in/out slightly - apparently the lip seals will suck air more easily.........
Not worried about originality......
Good arguments both sides........
