Show original supplier description
The PBM Dual Caliper Rear Drop Knuckles provide a performance-oriented upgrade through a forged and CNC-machined aluminum design. Featuring 25mm of roll center correction and a drop, these knuckles are engineered to improve roll center geometry while naturally reducing unwanted camber and toe change. This version integrates a Dynamic Toe Control System, allowing users to adjust toe rod positioning at the knuckle to fine-tune rear grip and consistency through the suspension stroke. Equipped with maintenance-free spherical bearings, these knuckles ensure smooth suspension movement. They feature integrated dual caliper brackets, eliminating the need for separate mounting hardware, and remain compatible with stock drum parking brakes and various Z33/Z34 braking systems. Compatibility includes 350Z, G35, 370Z, G37, and 2006+ M35 models. Please note that this kit requires PBM Rear Upper Arms (RUCA) because the upper ball joint is flipped horizontally to prevent binding. Additionally, PBM Toe Rods are required for the custom toe control system. Both the RUCA and toe rods are sold separately.
