Well I checked the back clearance its fine, and side clearance is .004 vs stock at .0025-.003

Thoughts? Generic range given is .0015 to .003, I would think this includes cars running 10K RPM or more also

HELPFUL TIPS FOR RING FITTING AND SEATING All pistons (including new ones) should be checked for proper ring to groove clearances.

Ring to piston groove back clearance should be a MINIMUM of .005" deeper than radial wall dimension of piston ring. If piston ring sticks out of groove by any amount, you have the wrong rings (see fig.1).

Ring to groove side clearance should be a minimum of .0015 to a maximum of .003" (see fig.1).
