Paco Motorsports eccentric locks

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! Paco Motorsports has come up with a simple solution to lock in your alignment perfectly. 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. You can use as many as eight on a car, although not all cams are as prone to slipping. Fits all NA and NB Miatas with the H shaped alignment bolt. If you have the older D bolts, you will need to upgrade - we offer a kit for that. If you have tubular V8Roadsters control arms, these can also be used on the problematic outer cam on the front lowers.
