These rear upper control arms are a bolt-in replacement for the stock Miata component. Designed to use the stock Miata bushing sizes, these arms give you the choice of either rubber or polyurethane bushings depending on your needs.
Easily adjust your camber quickly without affecting toe and reach alignment ranges that are not possible on stock arms.
To adjust, simply remove the bolt attaching the control arm to the upright and rotate the end of the arm before locking it down with the lock nut. Each 180 degree turn will change camber by 0.25 degrees, making it easy to make precise and consistent adjustments. There is also no chance of the setting slipping under load.
These adjustable rear control arms are properly contoured to clear the rear subframe. There is no limitation to compression travel and they can add up to 8 degrees of camber in each direction. Yes, you read that right!
Designed and fabricated in the USA, these have been through both Finite Element Analysis and real-world testing on high power track cars. They are stronger than required by a substantial margin.
Sold in pairs.
