I think there's only a grade on the 66.0 Mahle piston, matches to the barrel.

The oversizes are straight, bore to clearance.

Why not use the Mahle 2 ring piston. Replace the rings with wire TS1 items and you've got a decent set up.

You can buy a 1.5mm wire ring set at most tuners, I got my last set from Chiselspeed. 1mm rings on the Asso pistons came in to get round some problems with RB22s as I remember. TS1 kits had 1.5mm rings.
