not yet Deets, but here is the Wiseco ring which is the same as the Caber 1mm ring and is produced by NPR (nippon piston ring) the biggest ring manufacturer on earth apparently and the only place that makes a standard 1mm ring - it would have been cool to know this back in June when we started looking for a 1mm ring for the 181 full skirt race pistons LOL
Live and Learn - we are sending a bunch of cylinder/rings in for analysis Mahle, Gillardoni, Koblen Schmidt, Meteor, Farmertec, New West chrome and nikasil, as well as the Wiseco piston and ring
