• The control arm mount bracket with bushings holds the rear end of the front lower control arm in place. It constrains rearward / forward movement and helps stabilize lateral forces on the arm.
• It acts as a pivot and anchor point, allowing the control arm to move up and down with suspension, while resisting unwanted deflection under load (cornering, braking, acceleration).
• Because it’s in the rear position of the arm, it is subject to forces that might push or pull the arm fore/aft, so a stable mount is critical for alignment.
• In the HD / stiffer version, this mount limits deflection under load, which helps maintain alignment (especially toe) and reduces undesirable movement that can degrade handling precision.

• Clunking / knocking noises from the front suspension, especially from the control arm area
  
• Loose or vague steering feel, especially under cornering or over bumps
  
• Front-end alignment shifts under load, especially toe changes when braking or accelerating
  
• Uneven / accelerated front tire wear, especially on the front tires
  
• Reproducible shudder or instability during transitions (e.g. turning into a corner)
  
• Excessive vibration or harshness transmitted through the suspension if the buffering is compromised
  
  

• Improved Handling Precision: By reducing deflection under load, the HD mount helps maintain consistent suspension geometry, giving sharper steering response and more predictable behavior.
  
• Better Alignment Retention: Less movement helps the toe/camber settings stay where they should under braking, cornering, and load changes.
  
• Eliminates Noise & Play: Worn mounts let arms move, causing clunks or play. A stiffer mount restores tightness.
  
• Durability / Longevity: Higher durometer (stiffer) material resists aging, fatigue, and deformation better than softer factory rubber.
  
• Track / Sport Use Capability: On spirited driving or track days, the extra stability is noticeable — less wobble, better feedback, and more control.
  
• Better Front-End Behavior Under Load: Because the arm is more securely anchored, the forces are better managed, reducing unwanted movement that might upset balance.

• Porsche 964 (911) C4 1989-93

• Securing the Transmission - It keeps the transmission firmly in place, resisting movement under torque, acceleration, or deceleration.
• Absorbing Vibration & Noise - The rubber or elastomer element isolates drivetrain vibrations so they don't transmit harshly into the cabin.
  
• Controlling Movement / Deflection - Under load, transmissions tend to twist or shift slightly. A stiffer mount reduces that movement, improving shift feel, drivetrain alignment, and response.
  
• Maintaining Drivetrain Geometry - By limiting transmission motion, it helps preserve correct angles and alignment of drive shafts, couplings, and linkage.
  
  

• Clunks or thuds when shifting or applying torque
  
• Movement or slop in the transmission under load
  
• Delays or vagueness in shifts due to misalignment
  
• Excess vibration or drivetrain shake in the cabin
  
• Wear or stress on driveline components (e.g. drive shafts, joints)
  
• The transmission might feel “loose” under acceleration or deceleration

• Improved Shift Feel & Precision - A stiffer mount reduces movement that can dull shift quality or introduce slack.
  
• Better Drivetrain Alignment Under Load - Less motion keeps the transmission geometry stable, which protects driveshafts, joints, and couplers.
  
• Sharper Response - With less flex, the car responds more directly to throttle inputs without drivetrain “lag.”
  
• Balance of Comfort and Control - The HD rubber design offers more rigidity than stock but isn’t as harsh as solid mounts, so you still retain usable vibration isolation.
  
• Durability - A stiffer compound is more resistant to deformation, aging, oil, and heat, giving longer service life.
  
• Cost-Effective Upgrade - If the original bushing is degraded, installing an HD version is often a worthwhile performance upgrade.

Upgrade your Porsche’s front suspension precision with the Front Lower Control Arm Eccentric Centre Solid Bushing.
This solid centre bushing replaces the factory rubber insert in the front lower control arm’s eccentric pivot point, creating a direct, rigid connection between the control arm and subframe.
By eliminating unwanted flex and deformation, it ensures stable geometry, sharper steering response, and improved road feel.

• Increases Negative Camber “by Default” - Because the stud is offset outward, the wheel gets a small amount of negative camber without requiring changes at the top strut mount. This helps maintain better contact patch under cornering forces.
• Counters Camber Loss Under Load - In cornering, body roll or suspension compression tends to reduce negative camber (i.e. flatten the tire). The de-cambered joint helps offset that loss so the inside tire stays more planted.
  
• Improves Handling Stability and Turn-In - With more negative camber under load, the front end grips better, reducing understeer and making turn-in sharper.
  
• Mild Track / Performance Tuning Without Major Mods - Rather than needing to retrofit adjustable camber plates or change strut towers, this joint gives a modest camber “boost” in a bolt-on manner.
  
• Retains Full Ball Joint Functionality - It still allows articulation (steering, suspension travel) like a normal ball joint — the offset is only in its alignment, not in its motion.
  
  

• Knocking or Clunking Noises - A dull knock from the front suspension, particularly over bumps or while turning, often indicates play in the ball joint.
  
• Uneven or Excessive Tire Wear - Worn joints allow uncontrolled camber and toe changes, wearing the inside or outside edges of the front tires.
  
• Loose or Wandering Steering - When the ball joint develops play, the steering feels vague or “floaty” — the car no longer holds a consistent line through corners.
  
• Vibration or Shimmy at Speed - Free play in the joint can cause steering wheel vibration, particularly over rough surfaces.
  
• Visible Wear or Damage - Torn dust boots, leaking grease, or excessive movement when inspected during service are clear signs the joints need replacing.
  
• Inconsistent Handling Under Load - The car may feel unstable mid-corner or react unpredictably to bumps due to geometry shifts caused by worn ball joints.
  
  

• Restores Safety & Structural Integrity - The ball joint supports the front suspension load. A failure can cause complete loss of steering control.
  
• Maintains Proper Wheel Alignment - Fresh joints eliminate unwanted camber/toe drift and keep tires correctly aligned under all loads.
  
• Improves Steering Precision - Tight, new ball joints restore that crisp Porsche steering feel and predictable handling
  
• Enhances Cornering Grip - The de-cambered design adds built-in negative camber, improving tire contact and front-end grip through corners.
  
• Prevents Secondary Wear - Worn joints increase stress on tires, control arms, and suspension bushings — leading to expensive downstream repairs.
  
• Perfect for Performance & Track Use - The offset camber geometry helps maintain optimal contact patches during high lateral loads, reducing understeer and improving lap-to-lap consistency.

• In the Heavy Dusty semi-solid version, the stiffer rubber reduces unwanted flex while still providing some damping, hence a compromise between fully soft and fully rigid (solid) mounts.

• Engine / gearbox movement or “rocking” under throttle or deceleration
• Clunking or banging noises from the engine bay when shifting or applying torque
• Increased vibration in the cabin or floorboard
• Misalignment over time, causing stress or wear in driveshafts, couplings, or mount brackets
• Feel of looseness or lag in throttle response or drivetrain “lash”

• Sharper Response & Less Flex - Because mounts deflect less, the engine / gearbox stays more stable under load, improving throttle response, shift feel, and power delivery.
  
• Better Drivetrain Alignment - Less movement helps maintain correct angle relationships between engine, gearbox, driveshafts, etc., reducing stress and wear.
  
• Improved Stability Under Load - During hard cornering, braking, or acceleration, stiffer mounts help avoid drivetrain “twist” or slop, which can upset handling balance.
  
• Dampening Retained - Semi-solid design still absorbs vibration and noise more than fully rigid mounts, providing a balanced tradeoff for street use.
  
• Straightforward Installation - Because the inserts fit existing mount shells, installation is simpler — no need for custom brackets or drastic modifications.
  
• Good for Performance / Restoration Builds - Especially in cars that see spirited driving or occasional track use, the HD semi-solid mounts are a common upgrade that improves control without completely sacrificing comfort.

• The spring plate is part of the torsion bar suspension system: as the rear suspension moves, the torsion bar twists, and the spring plate (with its bushings) transmits those torsional loads to the chassis.
  
• The bushings isolate vibration and reduce noise, and they allow some controlled movement, while preventing excessive play.
  
• A correctly functioning spring plate + bushing assembly helps maintain rear ride height, alignment consistency, and smooth articulation of the rear suspension under dynamic load.
  
  

• Clunking / knocking noise at the rear when driving over bumps or under load.
  
• Sagging or uneven ride height at the rear (one side lower)
  
• Excessive rear vibration or harshness under acceleration or load
  
• Contact / rubbing noise — the worn bushings may allow the spring plate to contact its cover or adjacent metal surfaces.
• Degraded handling / instability in the rear under cornering
• Loss of the “tight” feel in the rear suspension; more play in the rear suspension response

• Restores Rear End Stability & Ride Quality: The upgraded, stiffer bushings reduce unwanted movement and maintain better control under load.
  
• Preserves Correct Geometry & Height: Keeps torsion bar and spring plate alignment tight, preventing sag or misalignment over time.
  
• Reduces Noise & Harshness: Eliminates metal-to-metal contact and vibration that results from deteriorated rubber.
  
• Better Durability: Heavy-duty rubber compound resists deformation, aging, heat, and oil.
  
• Protects Other Components: Reduces stress on torsion bars, suspension arms, and adjoining parts that might be damaged by excessive play.
  
• Essential for Restoration / Rebuilds: When rebuilding rear suspension or restoring a classic 911, these bushings are part of a full refresh to return the car to factory (or better) behavior.

Restore your Porsche’s legendary steering feel with the Front Wishbone Ball Joint Kit — the updated “New Type (FI16)” design used on 911 and 914 models.
The ball joint links the front lower wishbone (A-arm) to the steering knuckle, allowing controlled pivoting as the suspension moves. It maintains precise wheel geometry and ensures responsive handling.

• Steering play / looseness — the steering may feel vague or “sloppy.”
  
• Knocking or clunk noises — a distinct knock over bumps or during suspension travel.
  
• Uneven or rapid tire wear — particularly on the front tires, due to misalignment or movement under load.
  
• Vibration or shimmy — especially during cornering or when driving over uneven surfaces.
  
• Borderline geometry shifts — alignment may change subtly when load is applied or when cornering.
  
• Reduced road feel / control — the front end may feel less precise or less responsive.
  
  

• Restores Steering Precision & Control - Worn joints introduce slack and movement. Replacing them ensures crisp, direct response from your steering.
  
• Maintains Alignment Under Load - A healthy ball joint holds the wheel geometry consistent even when cornering or under load.
  
• Prevents Further Suspension Damage - Allowing play in a ball joint transfers forces to other components — control arms, bushings, knuckles, etc. Replacing it protects the rest of the suspension.
  
• Eliminates Noise & Harshness - New joints operate cleanly with no unwanted knocking or vibration.
  
• Safety & Reliability - Because the ball joint is a critical steering link, a failed joint can degrade or compromise safe vehicle control. Having robust, correctly functioning joints is essential.
