What is the main benefit of using an eccentric lockout kit?

This kit eliminates the factory eccentric bolts which can slip under load. This ensures your rear camber and toe alignment settings remain consistent, especially during hard cornering or track use.

Do I need adjustable control arms to use this kit?

Yes, you will need adjustable control arms to make camber and toe adjustments after installing the eccentric lockout kit. The kit itself locks down the alignment points, so adjustments must be made elsewhere.

What materials are used in the SPL Parts Eccentric Lockout Kit?

The lockout plates are CNC machined from 6061-T6 aluminum. The kit also includes strong, zinc-plated grade 10.9 bolts and lock nuts for a secure and reliable connection.

Product Details

SPL Parts is known for making well-built suspension components that help racers and performance drivers dial in their alignment. For your 2006-2015 Mazda MX-5 Miata (NC generation) or 2004-2011 RX-8, this Eccentric Lockout (EL) kit addresses a common issue with the stock alignment bolts.

The factory eccentric bolts used for rear camber and toe adjustments can slip when you're pushing the car hard, especially in corners. This means your alignment can change unexpectedly, affecting how the car handles. This kit replaces those stock eccentric bolts with solid lockout plates. These plates are CNC machined from 6061-T6 aluminum and come with strong, zinc-plated grade 10.9 bolts and lock nuts. The result is a zero-slip setup that keeps your rear alignment exactly where you set it. Keep in mind that to adjust camber and toe after installing this kit, you'll need adjustable control arms.

This kit includes everything needed for both the camber and toe arms on one car. It's proudly made in the USA, ensuring solid construction and reliable performance for your track days or spirited drives.
