    NOTE ON PISTON RINGS: We understand that the OEM rings are overpriced and have found an alternative in the Hastings Piston Rings that we offer above. These are OEM equivalent or better in quality, and we've used these rings in our own Spec Miata engine builds with no ill results.

    While there are many aftermarket options for Miata pistons, none offer the standard size for stock rebuilds or for racing classes with strict stock parts allowances, like Spec Miata. Mazda OEM pistons are just about the only choice - and a high-quality one - in standard size pistons.
