SRP has pistons in 81.25mm and was wondering if their piston rings would work with my 81.25 oem itr pistons? The reason i'm trying to go with their rings is that my oem piston ring's gap was too loose so I want to try JE's rings. Anyone have any experience with this rings and if you know if their file-fit or pre-gapped? Or any other type of piston rings reccomended that has size in 81.25? because I'm haven a hard time looking for them. thanks
