What This Product Does:
- The lower control arm rear bushing sits at the pivot or mount of the control arm on the front suspension. Its job is to allow controlled articulation of the arm while also restraining unwanted movement.
- By using a solid or high-density material instead of a standard soft rubber, the bushing significantly reduces unwanted flex or compliance. As a result, the suspension geometry (camber, toe, alignment) remains more stable under load (cornering, acceleration, braking).
- Less compliance in this mount means the front suspension reacts more precisely to driver input and chassis motion, improving handling stability, especially in modified or performance-oriented setups.
Symptoms & When To Need It:
- Front end feeling loose or vague in corners; the car may “step out” or have inconsistent behavior under heavy load.
- Uneven or accelerated tyre wear on the front due to alignment changing under load.
- The front suspension feels soft or sloppy, especially if the car has been lowered or has stiffer springs/anti-roll bars installed.
- The original rubber bushing shows signs of wear: cracking, splitting, excessive compression, or visible deformation.
- You’re upgrading the suspension and wish to reduce deflection in the pivot area to maximise benefits of other upgrades.
Why Replacement / Upgrade Matters:
- Over time the factory rubber bushings soften, deteriorate, or lose their design stiffness. This can degrade suspension accuracy and handling feel.
- Upgrading to a solid or high-density bushing restores the mount’s rigidity, keeps geometry more consistent, and enhances control — especially useful in performance, track, or modified cars.
- Better control arm mounting means less unwanted movement in the front suspension, which helps maintain alignment and improves driver confidence.
- For anyone restoring their Porsche or refreshing the chassis, upgrading key bushings like this one is a foundational step to ensure the car handles as well as it looks.
