Description
Kinematic Designs E9X Offset Camber Arm Spherical Kit
Fits: E9X chassis (all models using OEM-style rear camber/spring arms)
Rear geometry—refined.
The Kinematic Designs Offset Camber Arm Spherical Kit replaces the factory rubber bushing at the inboard side of the rear spring/camber arm with a high-precision, stainless steel press-in housing and a fully spherical bearing. This upgrade not only eliminates dynamic bushing deflection under load but also offsets the pickup point to partially restore proper rear suspension geometry on lowered E9X chassis cars.
By improving the rear roll center, this kit improves camber characteristics and increases the car’s kinematic resistance to roll, helping the vehicle stay flatter through corners without relying on stiffer springs or sway bars.
Key Features:
-
Stainless steel press-in housing for strength and durability
-
Offset geometry corrects rear roll center and improves camber gain on lowered cars
-
Aurora COM-series PTFE-lined spherical bearing – the gold standard for longevity and performance
-
Eliminates subframe-side camber arm rubber bushing deflection, improving consistency on track
-
Makes the rear camber arm fully spherical, increasing precision and feedback
-
Recommended tack weld installation prevents housing rotation during aggressive driving
This is an ideal solution for track-focused or aggressively driven street builds that want to maximize rear-end composure and geometry stability while maintaining the OEM arm layout. The included Aurora COM bearing offers best-in-class reliability, ensuring quiet operation and long service life even in harsh conditions.
Note: Professional press-in installation required. We strongly recommend tack welding the housing to the subframe after pressing to prevent rotation.
