Rear Drop Knuckle, Camber Arm, Control Arm Kit

The GKTECH rear suspension package offers a 20% combo discount for those looking to upgrade their vehicle's rear suspension components. This comprehensive package includes the essential rear drop knuckles, rear upper camber arms, and rear lower control arms, providing a coordinated approach to suspension tuning. All components are designed to fit the FR-S, GR86, and BRZ models. The rear drop knuckles are crafted from high-strength 4130 ChroMoly, offering significant weight reduction over OEM parts. They are engineered with new kinematics to improve anti-squat, bump steer, and camber gain curves, while also raising the roll center height. The knuckles include provisions for dual calipers to accommodate a hydraulic e-brake and are fully compatible with Brembo, GT, or GTS calipers. Furthermore, they feature integrated ABS sensor provisions for seamless OEM compatibility. Complementing the knuckles, the rear upper camber arms allow for precise adjustment of upper arm camber, effectively correcting the issue of camber change that often occurs when lowering a vehicle. These arms eliminate the flex and limitations of OEM rubber bushes, replacing them with super-smooth spherical joints for optimal operation. A unique design feature ensures the arm can be adjusted in-situ, and it provides ample driveshaft clearance, a common concern with rear drop knuckles. The package also includes on-car adjustable Rear Lower Control Arms (RLCAs). These arms provide 55mm of track adjustment and motion ratio adjustment, and can be used to lower the vehicle by 25mm. While typical adjustable LCAs alter camber, these incorporate additional features for enhanced tuning capabilities. The eccentric lockout kit, also part of the package, replaces adjustable toe arm bolts prone to slipping, ensuring alignment settings remain precise with +/- 4.85mm of toe change and -0.51 to -1.81 degrees of camber change.
