Just a thought, thin ring groves over stock groves. Engine builders would love to have the thin ring groves. Not having to deal with the stupid spacers would help reduce the man hours on building an engine. Not to mention the cost savings to the racers. How many of us had the spacers stick and not allow the rings to seal? Then you had to take apart the engine to free up the spacer and the rings. I have a new set of pistons on order as of last week. I would love to be able to legally have thin ring groves and never use spacers again.
