Description
SPL Parts 89-94 Nissan 240SX (S13) PRO Solid Subframe Conversion Bushings is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from 89-94 Nissan 240SX (S13) PRO Solid Subframe Conversion Bushings. SPL Parts engineers performance suspension components in the USA with an emphasis on strength, low friction, precise adjustment, and alignment control for track and high-performance street cars.
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.
When combined with quality dampers and tires, precise suspension links help make chassis tuning changes easier to feel, measure, and reproduce.
