I found an awesome deal on some piston rings and I'd like to share. I purchased Mahle 41850CP ring set for $100 through Summit. The set is for 3.898 bore 1.5, 1.5, 3.00mm and they have oversizes as well (I got 010, they don't have .005). The top ring is steel with plasma moly coating and the second ring is a cast iron napier. I found these to be a great value in piston rings and wanted to pass them onto you guys.
