Hi all, I measured the rings in my engine at the weekend and found that them to be out of spec, not by much but the worst was 0.11mm past the spec. 2 of my pistons also have the coating starting to flake off on them. I see that Cath Burrows has started to supply Wossner piston kits, has anyone used them before? Porsche want over £700 just for a set of rings and a new set of complete piston kits are just over £1000, they include new forged pistons, rings, gudgeon pins and clips.
