SPL Parts Solid Subrame Bushings - Porsche 911 (996) 99-05 / 911 (997) 05-12 is a chassis-specific suspension upgrade engineered for drivers who want more precise geometry control from Porsche 911 (996) 99-05 / 911 (997) 05-12. 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.

This low-compliance bushing or spherical-bearing upgrade replaces a soft factory pivot with a more precise articulation point. Reducing elastic movement allows the suspension arm to rotate through its intended path instead of deflecting under load, improving alignment consistency, steering response, and the repeatability of chassis behavior.

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 firmer connection may increase transmitted noise and vibration, but it is well suited to drivers prioritizing geometry control and feedback.

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.
