Factory front upper control arm outer bushings on R33 and R34 Skylines allow noticeable flex and lack any built-in adjustability, which hurts steering precision and alignment once the car is lowered or modified. SuperPro’s Front Control Arm Upper Outer Bushing Kit with Double Offset (part SPF1811K) replaces them with high-performance polyurethane bushings that reduce deflection while adding valuable geometry correction.

The double-offset design delivers 0.5° to 1° of camber adjustment plus positive caster on both sides, resulting in improved high-speed stability, crisper steering response, and a stronger return-to-center feel. This is a highly effective, non-tire-wearing upgrade that transforms front-end handling and confidence.
