Kits
OE Match Stabiliser Bar Mounting plate kit includes two plates — one for each side — to provide a balanced and secure mounting base for the front anti-roll bar on classic Porsche chassis. The stabiliser bar mounting plates provide a solid anchor surface for the anti-roll bar’s bush brackets, transferring roll-control forces into the chassis and helping maintain alignment and suspension geometry during dynamic handling.
SET OF 2
Fits:
Porsche 911/911 S / 912 1965 - 1967
Porsche 911 S/L / 912 1968 - 1969
Porsche 911 S / Carrera 2.7 / 911 T/E 1970 - 1973
Porsche 911 (930) Turbo 1795 - 1977
Porsche 914 1970 - 1976

The front anti-roll (stabiliser) bar plays a vital role in a Porsche’s suspension system by reducing body roll in corners and improving handling stability. The mounting plates serve as the interface between the chassis and the stabiliser bar bush brackets. Over time, original plates can corrode, deform, or fatigue, especially on older models exposed to road salt, moisture, or age-related wear.
Replacing both mounting plates with this OE Match set ensures proper anti-roll bar attachment, restores chassis integrity around the suspension points, and supports balanced handling performance - critical for spirited driving and classic restoration projects alike.
These plates are ideal for use during suspension rebuilds, anti-roll bar servicing, or full chassis restoration work.
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

Anti-Roll Bars (ARB’s) play an important role in a vehicle’s suspension system, helping to reduce body roll by transferring cornering load from one side of a vehicle to the other.
Often mounted to the vehicle’s chassis with rubber bushes, these bushes ensure the bar works as intended. To prevent the anti-roll bar from moving laterally within its mounts when turning, OE manufacturers will either bond the bushes to the bar, add dead-stops to the bar itself, or rely solely on the clamping pressure of the rubber.
But what happens when those bushes wear and need to be replaced? Often anti-roll bars with bonded bushes come as a costly complete assembly, so the alternative is to fit a more cost-effective unbonded polyurethane replacement, like the many we offer.
In most cases, friction from the bush will prevent any side-to-side bar movement. Still, when turning aggressively or cornering at higher speeds, a laterally shifting anti-roll bar decreases the efficiency and effectiveness of the bar, changing the dynamics of your suspension system in unpredictable ways. It also poses the risk of the bar fouling on other areas of the vehicle or suspension system.
