510/30/2009WRXtop,second and oil control ring thickness was too thick ,I dealt with Cosworth directly it cost me 3 sets of rings for this plus duty and shipping at the end it would have been cheaper to purchase a set of forged pistons and rings.needless to say I incurred this cost not the customer. Yes, if you don't know it s not made by Cosworth but by NPR of Japan . Wayne Alexis
