Front Lower Control Arm Centre Solid Bushing.
Enhance the front suspension precision of your Porsche with this high-performance centre solid bushing for the lower control arm. Specifically designed for the Porsche 996 and Boxster 986 models, this upgrade replaces the original rubber pivot insert with a hardened, high-density unit that dramatically reduces deflection and unwanted movement. With less compliance in the control arm pivot, the suspension geometry remains consistent under cornering, braking and load — giving you sharper steering feel, more accurate turn-in, and better overall handling. Ideal for performance upgrades, spirited road driving, or chassis refreshes, this component helps your Porsche deliver the crisp response and alignment stability it was built for.

What This Product Does:

• By replacing a flexible rubber insert with a solid or high-density material, this bushing significantly reduces unwanted deflection or compliance at the control arm pivot.
• With less pivot movement, suspension geometry (such as camber and toe) is held more consistently under cornering, braking, or load. That means better steering responsiveness and reduced unwanted change in alignment when the car is pushed.
• The result is a sharper, more precise front end feel, better turn-in, improved handling stability, and the ability to extract more from your tyres and suspension setup.
  
  

Symptoms Of Wear Or Need For Upgrade:

• Vague or soft steering feel — the front end may not seem as sharp as it used to be.
• Alignment shifting under load — camber or toe might move when cornering or braking.
• Uneven or accelerated tyre wear (especially inner/outer edges) due to geometry changes.
• Control arm bushings creaking, clunking or showing visible degradation.
• The front end may feel less stable or responsive, especially in a performance/setup car.

Why Replacement Or Upgrade Matters:

• Upgrading to a solid-insert bushing restores a firm, fixed pivot point for the control arm — this means the front suspension works as tightly as possible, which is especially important when you’ve upgraded springs, anti-roll bars, tyres, or you’re driving spiritedly or on track.
  
• It reduces unwanted movement in the front suspension system, which helps maintain factory alignment specs and avoids geometry compromises under load.
  
• The improved rigidity enhances feel, control, and driver confidence — the car will respond more directly to your inputs.
• It also prevents ongoing secondary wear — when a pivot is soft, other components (bushings, tyres, arms) are forced to compensate and may wear faster.
• For restoration builds, daily drivers with upgrades, or performance cars, this is a relatively modest investment that yields real handling improvement.

Fits On To Diagram Ref No 6

What This Product Does:

• Provides a fixed pivot / locational constraint - The “eccentric” or “center” position allows small adjustment for toe / camber alignment, but the solid insert gives a stable, rigid connection between arm and subframe.
  
• Reduces compliance / play - Unlike rubber bushings which deform, a solid bushing minimizes unwanted movement, improving feedback and response in suspension geometry under load.
  
• Improves alignment consistency - By being more rigid, it helps maintain the alignment settings (camber, toe) more consistently under dynamic loads (cornering, braking, acceleration).
  
• Enhances handling precision - Less movement in the pivot point sharpens turn-in and reduces deflection that can dull steering feel.
  
• May transmit more NVH - Because it is solid / rigid, vibrations or impacts may more readily pass through to the chassis compared to soft rubber bushings.
  
  

Symptoms / Signs Of Failure Or Need For Replacement:

• Steering vagueness or slop — control arms deflect, causing soft steering feel
  
• Alignment shifts under cornering / load — toe or camber changes mid-corner
  
• Uneven tire wear — due to inconsistent geometry
  
• Clunking or knocking noises at the front when going over bumps or during direction changes
  
• Degraded response or understeer because front grip is less precise
  
• Excessive deflection under load — the car might feel soft in the front during spirited driving
  
  

Why Replacement Or Upgrade Matters:

• Restores Suspension Tightness - Reduces flex and unwanted movement in a key pivot point, giving sharper steering feedback and more precise handling.
  
• Maintains Alignment Under Load - Better holds camber and toe settings under cornering, braking, and acceleration.
  
• Eliminates Slop and Play - Worn soft bushings allow movement; a better insert stops that, restoring original handling feel.
  
• Improves Driver Confidence - The front end feels more responsive, predictable, and controlled — especially in performance or spirited driving conditions.
  
• Cornering Performance Gain - The solid bushing supports sharper turn-in and reduces geometry change under lateral loads, improving grip and handling balance.
  
• Durability - Well-made solid inserts (especially aluminum / hardened construction) resist aging, deformation, and deterioration more than older rubber.

Fits On To Diagram Ref No 6

What This Product Does:

• The lower control arm rear bushing sits at the pivot or mount of the control arm on the front suspension. Its job is to allow controlled articulation of the arm while also restraining unwanted movement.
• By using a solid or high-density material instead of a standard soft rubber, the bushing significantly reduces unwanted flex or compliance. As a result, the suspension geometry (camber, toe, alignment) remains more stable under load (cornering, acceleration, braking).
  
• Less compliance in this mount means the front suspension reacts more precisely to driver input and chassis motion, improving handling stability, especially in modified or performance-oriented setups.

Symptoms & When To Need It:

• Front end feeling loose or vague in corners; the car may “step out” or have inconsistent behavior under heavy load.
  
• Uneven or accelerated tyre wear on the front due to alignment changing under load.
• The front suspension feels soft or sloppy, especially if the car has been lowered or has stiffer springs/anti-roll bars installed.
• The original rubber bushing shows signs of wear: cracking, splitting, excessive compression, or visible deformation.
• You’re upgrading the suspension and wish to reduce deflection in the pivot area to maximise benefits of other upgrades.

Why Replacement / Upgrade Matters:

• Over time the factory rubber bushings soften, deteriorate, or lose their design stiffness. This can degrade suspension accuracy and handling feel.
• Upgrading to a solid or high-density bushing restores the mount’s rigidity, keeps geometry more consistent, and enhances control — especially useful in performance, track, or modified cars.
• Better control arm mounting means less unwanted movement in the front suspension, which helps maintain alignment and improves driver confidence.
• For anyone restoring their Porsche or refreshing the chassis, upgrading key bushings like this one is a foundational step to ensure the car handles as well as it looks.

What This Product Does:

• Support and Mount the Transmission - They hold the gearbox (transaxle) in place relative to the chassis, keeping it aligned and preventing undesired motion.
  
• Absorb Vibration & Isolate Noise - The bushings dampen transmission vibration and drivetrain noise, improving comfort.
  
• Control Drivetrain “Slop” / Play - Stiffer bushings reduce the amount of twist or movement under torque load, minimizing driveline lash or unwanted movement when accelerating, shifting, or off the throttle.
  
• Maintain Geometry & Alignment - Properly mounted gearbox prevents shifting of driveline angles, which helps protect CV joints, driveshafts, and reduces undue stress elsewhere.
  
  

Symptoms Of Worn / Failing Transmission Bushings:

• Clunking, knocking, or banging noises during shifts, on throttle application, or when decelerating
  
• Driveline lash / slop — a sensation of delay or “slack” before power transfer
  
• Increased vibration or harshness felt in the cabin, especially under load or gear changes
  
• Gearbox movement — the transmission may move or twist noticeably when revs / torque change
  
• Wear on adjacent components — e.g. CV joints, driveshafts, differential support bearings may see accelerated wear
  
  

Why Replacement Matters:

• Restores Sharpness & Responsiveness — by eliminating soft or worn mounts, the drivetrain becomes more responsive and direct.
  
• Reduces Noise, Vibration & Harshness — a proper bushing absorbs and isolates vibration better than degraded old rubber.
  
• Protects Other Drivetrain Parts — reduces stress on CV joints, couplings, differential mounts due to movement or misalignment.
  
• Preserves Safety & Durability — under high torque loads (e.g. hard driving), a weak mount can twist excessively and cause damage.
  
• Better Handling Feedback — with less transmission movement, throttle transitions and engine braking feel more controlled and precise.
