Our Caster Adjuster allows you to tune this important setting that the factory left out. A must-have for cars that have extended lower control arms (GT3 control arms or eccentric monoballs) to correct for un-intended caster change that is caused by the extended arms.
Caster is also a great tuning aid for adjusting out understeer. Our Caster Adjusters let you tune the caster you need.
Two eccentric mounting points increase range of adjustment by up to 25mm. Choose from the inner bore for minor caster adjustments or the outer bore for extreme adjustments.
Rear Weight Bias
For the rear suspension, our Caster Adjuster can reduce rear overhang and rear weight bias. Cars with aggressive rear camber actually draw the wheels forward, increasing rear weight bias. Use our Caster Adjuster to compensate and even over-compensate for less rear weight bias than stock!

Maintain Proper Alignment
Our Caster Adjuster is solid aluminum to hold alignment settings precisely. Stock rubber bushings compress under load, allowing alignment to wander and making the car less predictable. Our solid design eliminates compression, improves precision and maintains geometry true.
