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 ri=
ng at or under 1mm in thickness. Generally, the thinner it is, the lower th=
e 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=C2=
=A0a ring of small holes=C2=A0
some piston makers have all sorts of clever micro 'tricks" like anti-flutte=
r 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

Hello Amici,
A discussion with my machine shop man led to some thoughts about piston rin=
g selection.
He recommended getting in touch with Total Seal. I of course took a look at=
their website to discover a mind boggling selection of ring types.
Can any of you share your ring choices?
I will be having JE Pistons make a custom set of forged pistons for me.
I am in need of ring thickness dimensions as well. Should this come from th=
e factory (GT6) pistons I currently have in the car?
Your thoughts are appreciated!
