chip-3door

chip i was talking about escort rst pistons where when people skim them they just skim 1mm off the top, even the low comp mahle rst pistons are like this just flat top 1mm lower, and i can see what you mean about the plate but i can get a 1mm thicker gasket so who knows how much that will lower the comp ratio 8:3.1 standard so around 7:5.1 ?
