R33 and R34 Skylines often lose sharp steering feel and high-speed stability as the front upper inner control arm bushings wear. SuperPro’s Front Control Arm Upper Inner Double Offset Bushing Kit (part SPF3154K) tackles this with precision polyurethane bushings that not only firm up the suspension but also introduce beneficial geometry changes.
The double-offset design adds positive caster while providing up to 0.5° of camber adjustment. This creates stronger self-centering, more responsive turn-in, and improved straight-line stability — all without increasing tire wear. It’s one of the most effective geometry upgrades you can make for better overall handling.
