Front control arm bushing kit. Porsche 911/912/914  ❭  91134190999

Heavy duty (Fast Road & street) Front Control Arm Bushing (Rear Position)
One kit includes 2 bushings ( for one control arm)

Fit:
Porsche 964 1989-94 Rear Bushing Sport Hardness
Porsche 993 1995-98 Rear Bushing Sport Hardness
Porsche 944 1985-95 W/ Alum. Arms Front Bushing Sport Hardness

The control arm bushing is comprised of two halves for each arm. Kit includes two halves for one complete bushing.

High Density front control arm bushings can eliminate vibration often caused by ageing OEM units, and better maintain steering feel under heavy acceleration and braking. These bushings replace the rear bushing in the front control arm of 993s and 964s and will reduce suspension deflection more precisely maintaining suspension geometry and alignment. Featuring a 25% increase in durometer, our units reduce suspension deflection under load resulting in a crisper and more direct steering feel. Street and track cars owners alike will enjoy a more planted and precise front end.

Front control arm front bushing.
Price is per each. 2 req'd per car.

Fits:
Porsche 964 1989-94 OEM Hardness
Porsche 993 1995-98 OEM Hardness


We see control bushings fail with great regularity on 964 cars. Failures seem mileage independent, the rubber deteriorates due to age. The symptom is vibration felt in the steering wheel.

Stock-hardness – Restores performance and ride quality to original.

Sport-Hardness – Similar to the 993 RS bushing, sport hardness rubber is about 25% firmer. Deflects less under cornering loads and thereby maintains alignment more precisely.

Front Control Arm Front Bushing, Sport Hardness (Forward Position).
Upgrade your Porsche’s front suspension with this Front Control Arm Front Bushing – Sport Hardness.
Designed for Porsche 964 and 993 models, this bushing replaces the factory front mount of the lower control arm, providing a stiffer, more durable connection between the wishbone and subframe.
The sport hardness compound (approximately 25% stiffer than stock rubber) minimizes unwanted flex and maintains consistent alignment under load. The result is improved cornering stability, sharper steering response, and better feedback without significantly compromising ride comfort.

What This Product Does:

• The bushing is the interface between the control arm and the subframe / mounting point.
• It permits controlled movement (for suspension travel) while resisting unwanted motion so the wheel alignment remains stable.
  
• The firmer (sport) version deflects less under cornering, braking, or acceleration loads, helping maintain alignment geometry under load.
  
• By resisting deflection, it helps reduce unwanted movement in the front suspension, improving handling precision and steering feedback.

Symptoms Of A Worn / Failing Bushing:

• Vibration felt in the steering wheel, especially under certain loads or speeds (“shudderiness”)
• Looseness / play in the front suspension — less precise steering response
  
• Alignment changes under load — the front toe may drift during cornering or braking
  
• Clunking or knocking noises over bumps or from the front suspension
  
• Uneven or increased tire wear, especially on the front edges
  
• A degraded “feel” to the front end — less sharpness or a vague response in turns

Why The Sport Hardness Version Matters:

• Better control under load: Because this bushing is stiffer than stock, it deflects less in aggressive driving, helping maintain suspension geometry (camber / toe) more accurately in dynamic conditions.
  
• Sharper steering feel: Less compliance means more direct response, reducing mushiness in the front end.
  
• Reduced suspension movement / slop: Particularly helpful in performance, track, or spirited road use where loads are higher.
  
• Longer service life (in some cases): A harder compound may resist aging and fatigue better in high-stress conditions, though it may transmit slightly more noise, vibration compared to softer rubber.
  
• It still retains enough flexibility to absorb some road input, balancing performance with comfort.
