For Sale: Stock bore M20B25 piston rings. Ductile iron with moly coating top ring just like you would get from Metric Mechanic.
They are brand new in the box because I ended up boring the block and using an identical but larger set of piston rings. After trying Total Seal gapless, Goetze, and Mahle piston rings, these rings are best and what I use in all of my Spec E30 engine builds. They seat near instantly, seal great, and will work will in a street or track driven M20.
I paid $235 and would like $200, but will except reasonable offers. They are doing me absolutely no good and I'd like to see them get some use.
