Rear upper control arms on S13, S14, and S15 Silvia/180SX models lose precision quickly once lowered or modified, often causing alignment drift and reduced rear grip. SuperPro’s Rear Control Arm Bushing Kit with Double Offset (part SPF1869K) replaces the stock bushings with high-performance polyurethane that not only eliminates flex but also provides adjustable camber correction of 0.5° to 1° through inner and outer eccentric bushings.
This double-offset design is perfect for lowered cars or those needing precise geometry tuning to maximize tire contact and cornering performance. The complete kit includes all necessary hardware for a strong, long-term upgrade that sharpens rear stability and handling feel.
