Description
SPL Parts 89-98 Nissan 240SX (S13/S14) PRO Solid Subframe Bushings is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from 89-98 Nissan 240SX (S13/S14) PRO Solid. SPL Parts is a U.S.-based performance-suspension specialist that develops motorsport-oriented chassis hardware for precise alignment, low compliance, and repeatable setup changes.
These solid subframe bushings replace compliant OE rubber mounts to locate the subframe more rigidly relative to the chassis. Reducing subframe movement keeps suspension pickup points from shifting under acceleration, braking, and cornering, which makes toe and camber behavior more repeatable and improves the driver's connection to the rear or front axle.
Why it matters: On this application, the goal is to keep the tire and upright closer to the intended alignment as loads rise, giving the driver a more repeatable platform for braking, turn-in, mid-corner balance, and power application. The tradeoff is increased noise, vibration, and harshness, making this upgrade best suited to performance-focused street cars and track builds where precision is prioritized over isolation.
For best results, set the final geometry around the vehicle's tire, ride height, and intended street/track use rather than relying on generic factory targets.
