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

OEMatch Anti Roll Bar — Control, Stability, Comfort
Anti-roll bars link the left and right suspension to limit body roll during cornering, helping to maintain tyre contact and steering precision on Porsche models. OEMatch offers anti roll bar items and associated mounting parts selected for Porsche applications, intended for servicing, tuning and restoration where predictable handling is required.
Available Types
- Standard replacement anti roll bars
- Reinforced and heavy-duty bars
- Adjustable torsion bars for chassis tuning
- Drop links, end-links and mounting kits
- Bush kits and rubber isolators
Understanding OEMatch Anti Roll Bar
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original anti roll bars.
OE (Original Equipment) refers to parts matching original specifications for the anti roll bars and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM anti roll bars engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. OEMatch focuses on anti roll bar-related items selected for Porsche applications.
Benefits Include
- Reduced body roll for improved balance and steering precision
- Better tyre contact through corners for more predictable grip
- Restored chassis balance that aids driver confidence and control
Why Anti Roll Bar Wear and Fail
- Worn, cracked or perished bushes that allow excess movement
- Corrosion or metal fatigue in the bar, drop links or mounting brackets
- Seized joints or degraded rubber isolators from environmental exposure
The Importance of Replacing with OEMatch Anti Roll Bar
Replacing worn anti roll bar components restores the chassis geometry and damping balance that Porsche models rely on for predictable handling. Using purpose-selected replacement parts reduces unwanted noise and uneven tyre wear and helps maintain the original steering response. For maintenance, tuning or full suspension renewal, choosing components that match mounting points and stiffness characteristics keeps handling consistent with the vehicle’s setup.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances for Porsche models
- Options in different stiffness ratings to tune front-to-rear balance
- Comprehensive kits that include bars, drop links and bushes for a single installation job
