SPL Parts 2016+ Mazda Miata (ND) Eccentric Lockout Kit

SPL Parts is known for making well-built suspension components that help racers and performance drivers get the most out of their cars. If you're pushing your 2016+ Mazda MX-5 Miata hard, especially on track or autocross, you know how frustrating it can be when your rear alignment changes unexpectedly. The factory eccentric bolts used for camber and toe adjustments can slip under high cornering loads, throwing off your setup and affecting handling. This Eccentric Lockout (EL) kit is designed to solve that problem.

By replacing the stock eccentric bolts, this kit ensures your rear alignment stays exactly where you set it, no matter how aggressive your driving. The lockout plates themselves are CNC machined from strong 6061-T6 aluminum, and they come with zinc-plated grade 10.9 bolts and lock nuts. This combination provides a zero-slip connection that holds firm. Keep in mind that once you eliminate the stock eccentric bolts, you'll need adjustable control arms to make your camber and toe adjustments. This kit includes all the necessary washers and bolts for both the camber and toe arms, making it a complete solution for one car.

This kit is proudly made in the USA, ensuring solid construction and attention to detail. It's a straightforward way to improve the consistency of your Miata's rear suspension performance when you need it most.
