if JE are making pistons, surely they will supply rings???
In general, ring & piston design has improved a lot in recent decades
in most cases, you will head for a nitrided steel top ring, a steel centre
ring (possibly filled with something) and a 3-piece segmented oil ring
in many cases, they can now make a perfectly satisfactory top and second
ring at or under 1mm in thickness. Generally, the thinner it is, the lower
the friction but really thin rings require super careful honing and bed-in
best practise is to not have any slots behind the oil ring, but rather a
ring of small holes
some piston makers have all sorts of clever micro 'tricks" like
anti-flutter grooves they machine in the lands between the rings
Whomever supplies the rings will specify the final hone finish required
best practise is to use double "spiro-locks" to retain the gudgeon pin
