Drop Link Racing Uniball Version, Rear Right. Porsche 964

Drop Link Racing Uniball Version, Rear Right.
Maximise the performance of your Porsche 911 (964) rear stabiliser system with this high-performance racing drop link. Specifically engineered for the rear right side of the 1989-94 911 (964 C2/C4/RS/Turbo), this part features a durable spherical uniball joint in place of the standard rubber bushing. The precision joint allows near-zero compliance, delivering sharper rear-end response, improved cornering stability and long-term durability. Ideal for spirited driving, track days or any 964 where rear suspension performance matters.

• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 964 (911) RS 3.6L 1991-93
• Porsche 964 (911) RS 3.8L 1991-93
• Porsche 964 (911) TURBO 3.3L 1991-93

What This Product Does:

• The rear drop link connects the rear anti-roll bar (also called stabiliser bar) to the rear suspension arm or axle carrier. Under cornering, the anti-roll bar transfers load from one side of the rear suspension to the other, helping reduce body roll and maintain tyre contact.
• In a standard link, the joint usually has a rubber or polyurethane bushing that allows articulation but with some compliance. The uniball version replaces the bushing with a spherical bearing which allows joint motion with much less compliance and greater precision.
  
• The result: faster, sharper response of the stabiliser bar to suspension movement; less flex in the link; more direct force transfer; improved rear stability during cornering or dynamic driving.

Symptoms & Signs Of Wear / When To Upgrade:

• Clunking or knocking noises from the rear suspension when going over bumps or during rapid direction changes — likely indicating wear in the link joint or bushing.
  
• Excessive body roll or vague rear end feel in corners — if the anti-roll bar isn’t applying its load properly because the link is loose or soft, the rear end can feel less stable.
  
• Uneven rear tyre wear (especially outer shoulder) or strange rear alignment behaviour — since the stabiliser may not be transferring load correctly under dynamic conditions.
  
• If you’ve upgraded other suspension components (stiffer springs, wider tyres, track usage) and the rear still “feels soft” or delayed — the link may be the “weak link” in the system.
• On inspection: you might see excessive play in the link joint, torn or degraded boots, corrosion, or a bent link. When an OEM rubber bushing link is worn, the uniball version is a logical upgrade path.

Why This Upgrade Matters:

• Reduced compliance = sharper handling: By replacing a rubber-bushed link with a spherical bearing, you reduce unwanted movement. This means the rear anti-roll bar is engaged more directly, giving you a firmer, more predictable rear end under cornering.
  
• Supporting other upgrades: If you have made other suspension enhancements (springs, dampers, anti-roll bars, tyres), then the standard link might become the limiting factor. Upgrading to the uniball version ensures your rear stabiliser system can operate at its full potential.
  
• Durability and precision: Spherical bearings are more robust for high load/track usage. They provide longer life under high cornering forces compared to rubber bushings which degrade over time.
  
• Safety and control: The rear stabiliser system contributes to chassis behaviour in transitions, over bumps, and in dynamic manoeuvres — if the link is worn or soft, the car’s handling rear-end can become unpredictable. Upgrading improves confidence.
  
• Value for performance builds: For a performance or track-oriented Porsche 964, having high-quality suspension components (including drop links) is part of the upgrade footprint and contributes to the car’s usability and resale value.
