Diagram ref no 22
The front anti-roll bar connects across the front suspension and helps reduce body roll during cornering. By transferring suspension load between the left and right front wheels, it supports more stable handling, improved road feel, and predictable front axle control.
Functions
• Replaces the front anti-roll bar / stabiliser bar
• 15 mm diameter specification
• Helps reduce front body roll during cornering
• Supports stable and predictable handling
• Helps maintain correct front suspension behaviour
• Replaces bent, corroded, worn, damaged, or missing original anti-roll bars
• OE Match replacement for classic Porsche suspension repair and restoration.
Why Replace This Part?
Front anti-roll bars can become corroded, bent, worn at the mounting areas, damaged by impact, or affected by previous suspension repairs. A worn or damaged anti-roll bar may cause poor handling, excessive body roll, knocking noises, uneven suspension response, or incorrect suspension geometry. Replacing the bar helps restore correct front suspension stability and OE-style handling characteristics.
When to Replace This Part
• The front anti-roll bar is bent, rusty, damaged, or missing
• Excessive body roll is felt during cornering
• Knocking or movement is present around the anti-roll bar mounts
• The front suspension is being rebuilt or restored
• Anti-roll bar bushes, drop links, or mounting hardware are being replaced
• Incorrect or non-original anti-roll bar parts have been fitted
• The vehicle is undergoing Porsche 911 or 914 suspension restoration.
Where it fits on the car
This anti-roll bar fits across the front suspension assembly on Porsche 911 and 914 models. It works with the relevant front anti-roll bar bushes, links, and mounting hardware according to the factory suspension layout.

Diagram ref no 27
The mounting plate acts as a foundation for the stabiliser bar brackets and bushings, ensuring they remain correctly positioned against the chassis. Over many years of service, original plates can twist, crack, corrode, or wear, which can compromise the efficiency of the anti-roll system and lead to handling inconsistencies.
This OE Match replacement plate is ideal for suspension rebuilds, restoration projects, or upgrades where secure stabiliser bar attachment is required. It installs directly in place of the original with no modification needed and helps maintain the vehicle’s classic handling characteristics.
The stabiliser bar mounting plate provides a solid anchoring surface for the anti-roll bar bush brackets. By keeping the stabiliser bar correctly positioned, it helps reduce body roll during cornering, enhances steering precision, and maintains chassis stability under lateral loads.
Function:
• Anchors stabiliser (anti-roll) bar bush brackets to the chassis
• Maintains correct geometry and load transfer for suspension dynamics
• Reduces body roll and improves cornering stability
• Durable, corrosion-resistant construction for long service life
A worn, bent, or corroded stabiliser bar mounting plate can cause the anti-roll bar to shift under load, leading to decreased handling precision, increased body roll, and uneven suspension response. Replacing it with an OE Match mounting plate restores secure attachment for the stabiliser bar assembly, enhances lateral stability, and helps retain the intended driving dynamics of your classic Porsche.
When to replace:
• Visible rust, cracks, or deformation of the mounting plate
• Excessive play or movement in the anti-roll bar under cornering
• During front suspension rebuild or stabiliser bar service
• After collision or chassis repair affecting suspension mounts
