The OE Match Front Auxiliary Support Frame Bush Set of 4 is a premium-quality replacement suspension mounting kit designed to securely locate and isolate the front auxiliary support frame (subframe) from the chassis on compatible Porsche models. Manufactured to OE specifications for fit, material quality and durability, these bushes absorb vibration, reduce noise and maintain the correct alignment of the front suspension and steering components.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
Diagram Ref No 8
Manufactured from high-quality automotive-grade rubber bonded to precision-engineered steel sleeves, the bushes are designed to withstand continual road impacts, engine vibration, suspension loads and exposure to oil, moisture and road contaminants. Supplied as a complete set of four, they provide a direct OE-style replacement for all front auxiliary support frame mounting positions, making them ideal for suspension overhauls, chassis restoration and preventative maintenance.
What This Product Does:
- Secures the front auxiliary support frame to the chassis.
- Absorbs vibration and road shock.
- Reduces the transmission of noise into the cabin.
- Maintains correct subframe alignment.
- Supports accurate suspension and steering geometry.
- Minimises unwanted movement of the front subframe.
- Restores factory ride quality and handling.
- Forms an essential part of the front suspension mounting system.
Symptoms Of Wear Or Failure:
- Knocking or clunking noises from the front suspension.
- Increased vibration felt through the steering wheel or cabin.
- Excessive movement of the front subframe.
- Poor steering precision.
- Wandering or instability during braking.
- Uneven tyre wear caused by suspension movement.
- Cracked, split or deteriorated rubber bushes.
- Visible separation between the rubber and metal sleeve.
- Reduced ride comfort.
- MOT or vehicle inspection failure due to worn suspension mountings.
Why Replacement Matters:
- The front auxiliary support frame bushes are subjected to constant suspension loads, engine vibration, braking forces and road impacts. Over time, the rubber compound can harden, crack or separate from the bonded metal sleeves, allowing unwanted movement of the subframe and affecting the vehicle's handling characteristics.
- Worn bushes can lead to increased vibration, suspension noise, inaccurate steering response and changes in wheel alignment. If left unresolved, excessive subframe movement can accelerate wear on suspension and steering components while compromising ride quality and driving confidence.
- Replacing all four bushes at the same time restores the original rigidity, alignment and isolation of the front auxiliary support frame. The OE Match Front Auxiliary Support Frame Bush Set is manufactured to OE standards using premium-quality materials, providing factory-style fitment, long-lasting durability and dependable suspension performance, ensuring the comfort, stability and handling expected from your Porsche.

Fits:
Porsche 912 1969
Porsche 911 T/E/S 1969 - 1973
Porsche 911 1974 - 1989

The front crossmember reverse lever adjusting screw provides fine-tuning of the reverse lever assembly on the front suspension crossmember. It enables precise adjustment of the torsion bar preload and suspension geometry, which affects ride height, wheel alignment, and handling balance.
This screw works within the front crossmember mechanism to establish the correct positioning of the reverse lever, which in turn ensures that the torsion bars and lever arms are calibrated accurately to support the vehicle’s weight and suspension movements.
The front suspension crossmember and associated reverse lever mechanism play a key role in how the vehicle’s torsion bars and front suspension geometry behave. A worn, damaged, or incorrect adjusting screw can cause:
• Improper torsion bar preload
• Uneven or incorrect ride height
• Poor alignment and handling issues
• Uneven tyre wear
• Steering imbalance
Replacing a worn or corroded component restores proper adjustment capability, enhances suspension accuracy, improves handling response, and helps maintain original suspension setup.
Replace this adjusting screw if:
• Threads are damaged, corroded, or worn
• Adjustment becomes difficult or imprecise
• You’re performing front suspension removal or rebuild
• Ride height or alignment cannot be correctly set
• Front crossmember or torsion bar work is underway

Front Auxiliary Support Frame Rubber Bush (Control Arm
Bush)
Sold each - 2 required per car
Restore the original ride quality and steering precision of
your classic Porsche with this OE Match Front Auxiliary Support Frame Rubber
Bush (Control Arm Bush). Manufactured for precise
fitment and long-lasting durability, this replacement bush supports the front
auxiliary support frame while isolating vibration and allowing controlled
suspension movement.
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
Diagram ref no 8
The front auxiliary support frame forms a vital part of the
front suspension assembly, providing a secure mounting point for the control
arms and suspension components. The rubber bushes absorb road shocks and
vibration while allowing the suspension to articulate smoothly. Over time,
exposure to age, heat, oil contamination and repeated suspension movement
causes the original rubber to harden, crack or compress, leading to degraded
handling and increased noise.
Replacing worn suspension bushes restores the correct geometry of the front suspension, improves steering accuracy and helps return the smooth, predictable handling characteristics that early Porsche 911 and 912 models are renowned for.
Whether you're carrying out a concours restoration, rebuilding the front suspension or replacing ageing rubber components, this OE Match bush provides an excellent solution for maintaining factory-style suspension performance.
What Does the Front Auxiliary Support Frame Bush Do?
This rubber bush cushions and supports the connection between the front auxiliary support frame and the suspension assembly.
Its primary functions include:
- Supporting the front suspension assembly.
- Isolating road vibration and noise.
- Allowing controlled suspension movement.
- Maintaining correct suspension geometry.
- Reducing stress on suspension components.
- Improving steering stability and ride comfort.
A healthy suspension bush helps ensure the suspension operates smoothly while maintaining precise wheel alignment.
Why Replace the Front Auxiliary Support Frame Bush?
Rubber suspension bushes naturally deteriorate after years of service.
Common reasons for replacement include:
- Perished or cracked rubber.
- Bush compression and deformation.
- Excessive suspension movement.
- Oil contamination.
- Suspension noise.
- Steering wander.
- Front suspension restoration.
- Preventative maintenance.
Replacing worn bushes restores proper suspension support and improves overall vehicle handling.
Symptoms of a Worn Control Arm Bush
A deteriorated bush may result in:
- Vague or imprecise steering.
- Knocking or clunking from the front suspension.
- Excessive suspension movement.
- Uneven tyre wear.

Replacement rubber mount for the front auxiliary support frame that supports the front suspension and steering components on early Porsche 911 and 912 models. This bushing cushions and secures the support frame to the chassis or body mounts, helping to isolate road vibration, maintain alignment, and ensure stable suspension geometry.
Sold each, 2 required per vehicle.
Fits:
Porsche 911 2.0L 01/1963 - 07/1967

This bushing installs directly in place of the factory part without modification.
This replacement bushing is especially useful during restoration, front-end maintenance, or when the original mount exhibits signs of wear - ensuring safe, predictable handling and preserving chassis integrity.
Worn or degraded support-frame bushings can lead to excessive play under load, compromising suspension geometry and causing unstable handling, uneven tyre wear, or unpredictable steering feedback. In addition, degraded rubber can transfer vibration and noise into the cabin, reducing comfort and potentially accelerating wear on other suspension or chassis components. Replacing with a correct-spec bushing restores firm, damped support - preserving handling precision, ride comfort, and the structural integrity of the front sub-frame.
When to replace. Consider replacing when:
• The original bushings are cracked, flattened, perished or visibly damaged
• There is clunking, looseness or unstable handling under braking, cornering, or uneven roads
• You are performing a front suspension, frame or chassis overhaul
• You are undertaking a restoration or recommissioning of a classic 911/912
