Agreed. If you're going to be re-ringing your engine every 30k - 50k miles, it's a waste of money.

That being said, some of the newer HP pistons available from Probe, TFS, and others are using 1/16" rings. Good for racing, but not so good for mileage. If I didn't want to be replacing rings every 30k - 50k miles, the gapless rings from either Total Seal, or Childs & Albert might be just the ticket for extended mileage with a performance piston.

So, the question is, those of you using gapless rings presently, any problems or complaints?
