Front Lower Control Arm Eccentric Centre Solid Bushing.

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.
Sold Each.
x2 Required Per Car.

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.
