Product Information

Front Lower Control Arm Centre Solid Bushing.
Enhance the front suspension precision of your Porsche with this high-performance centre solid bushing for the lower control arm. Specifically designed for the Porsche 996 and Boxster 986 models, this upgrade replaces the original rubber pivot insert with a hardened, high-density unit that dramatically reduces deflection and unwanted movement. With less compliance in the control arm pivot, the suspension geometry remains consistent under cornering, braking and load — giving you sharper steering feel, more accurate turn-in, and better overall handling. Ideal for performance upgrades, spirited road driving, or chassis refreshes, this component helps your Porsche deliver the crisp response and alignment stability it was built for.

What This Product Does:

By replacing a flexible rubber insert with a solid or high-density material, this bushing significantly reduces unwanted deflection or compliance at the control arm pivot.
With less pivot movement, suspension geometry (such as camber and toe) is held more consistently under cornering, braking, or load. That means better steering responsiveness and reduced unwanted change in alignment when the car is pushed.
The result is a sharper, more precise front end feel, better turn-in, improved handling stability, and the ability to extract more from your tyres and suspension setup.

Symptoms Of Wear Or Need For Upgrade:

Vague or soft steering feel — the front end may not seem as sharp as it used to be.
Alignment shifting under load — camber or toe might move when cornering or braking.
Uneven or accelerated tyre wear (especially inner/outer edges) due to geometry changes.
Control arm bushings creaking, clunking or showing visible degradation.
The front end may feel less stable or responsive, especially in a performance/setup car.

Why Replacement Or Upgrade Matters:

Upgrading to a solid-insert bushing restores a firm, fixed pivot point for the control arm — this means the front suspension works as tightly as possible, which is especially important when you’ve upgraded springs, anti-roll bars, tyres, or you’re driving spiritedly or on track.
It reduces unwanted movement in the front suspension system, which helps maintain factory alignment specs and avoids geometry compromises under load.
The improved rigidity enhances feel, control, and driver confidence — the car will respond more directly to your inputs.
It also prevents ongoing secondary wear — when a pivot is soft, other components (bushings, tyres, arms) are forced to compensate and may wear faster.
For restoration builds, daily drivers with upgrades, or performance cars, this is a relatively modest investment that yields real handling improvement.
