Ring sets are priced as a four piston set and include all three rings per cylinder (compression, compression, oil) Sizes range from Standard (82.975 mm / 3.2667" in max diameter), .25mm oversize (0.010"), and .50mm oversize (0.020") Stock rated 9.0:1 compression ratio 80 grams assembly weight (for Standard diameter)
Availability: Standard Normally In Stock - Oversize Normally Special Order
Shipping: In-Stock Items ship USPS Priority unless noted otherwise
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.
