Paco Motorsports eccentric locks for RX-8, NC and ND (small bolt)

If you've ever run your Miata on the track, you know that those alignment cams can slip. If you're lucky, it just ruins a session. You can change out the bolts on a regular basis and crank the torque way up on the nuts - but there's always that risk. Until now! A few years ago, Paco Motorsports came up with a solution for the NA and NB - and they're now available for the NC! These locks replace the offset washer on an alignment bolt and prevent it from moving. They key into the same ridges used by the stock washer. The center section can be placed in any one of 16 positions, and you keep the same range of alignment - maximum negative camber is still maximum negative camber. To use, align your car as normal. Then swap out the stock washer for the lock and retorque. It'll never slip again. Be aware that these parts do complicate your alignment and your alignment tech might call you (or us) names - it's worth it if you drive your car hard enough to have slipping eccentrics, though.  Sold individually, two needed per car. This lock is for the small M12 cams, found on the front of the rear lower arms. The vertical bolts found on the rear of the front lower arms do not need locks.
