The rear subframe mounts on S13, S14, and S15 Silvia/180SX models are prone to flex and degradation, especially on lowered or high-power builds, leading to drivetrain shift, wheel hop, and vague rear handling. SuperPro’s Subframe Mount Bushing Kit (part SPF3774K) replaces the soft factory rubber with high-performance polyurethane shell bushings that dramatically stiffen the subframe-to-chassis connection for improved rigidity and more direct power transfer to the rear wheels.
This upgrade results in tighter rear-end response, reduced unwanted movement, and noticeably better traction and stability during cornering, acceleration, and drifting while still offering reasonable street comfort.
