Description
SPL Parts 2014+ Infiniti Q50 / 2017+ Infiniti Q60 Rear Traction Arms - Dogbone Version is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from Dogbone Version. SPL Parts is a U.S.-based performance-suspension specialist that develops motorsport-oriented chassis hardware for precise alignment, low compliance, and repeatable setup changes.
This adjustable longitudinal suspension link replaces a compliance-heavy factory connection and provides a more direct way to control wheel motion under acceleration and braking. Depending on the chassis geometry, link-length changes can also be used to influence anti-squat characteristics and wheelbase position. Reducing deflection helps the rear suspension react more consistently to throttle inputs, improving mechanical grip, transient response, and confidence when loading the tire on corner exit.
Why it matters: On this application, the goal is to keep the tire and upright closer to the intended alignment as loads rise, giving the driver a more repeatable platform for braking, turn-in, mid-corner balance, and power application. Adjustment is most valuable on lowered or competition cars where the factory geometry has moved away from its intended operating window.
For best results, set the final geometry around the vehicle's tire, ride height, and intended street/track use rather than relying on generic factory targets.
