The stock eccentric bolts provided by Mazda for small rear toe adjustments tend to slip under high cornering loads, causing changes to the rear alignment.  Our SPL Parts NC Miata Eccentric Lockout (EL) kit eliminate the stock eccentric bolts to keep your rear alignment where you set it. You must have adjustable toe arms in order to adjust rear toe after eliminating the stock eccentric bolts.  Our lockout plates are CNC machined from 6061-T6 Aluminum and supplied with zinc plated grade 10.9 bolts and lock nuts for absolutely zero-slip. One kit includes washers and bolts for both toe arms.

Sold as complete kit for one car.

Made in the USA.
