Rear Control Arm Mounts for the 944 and 924s can both eliminate clunks from failing factory units and restore proper suspension geometry in your street or track car. Flex in the factory bushing allows significant alignment changes, specifically to toe, under heavy braking and acceleration as these mounts are responsible for controlling vertical movement of the front control arm. These mounts will locate the front end much better under the sustained loads often experienced on track and in the rigors of everyday driving.

What This Product Does:
- 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.
Symptoms / Signs Of Wear:
- 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 Rear Subframe | Design911 Suspension Upgrade Components for Rigidity, Alignment & Handling Precision
The rear subframe is the structural foundation of your Porsche’s suspension and drivetrain assembly. It supports the suspension arms, differential, and other critical components while maintaining precise geometry under high load. A strong, correctly aligned subframe ensures stability, balance, and predictable handling — particularly during hard acceleration and cornering.
At Design911, we supply a comprehensive selection of rear subframes and upgrade components, engineered for precision, strength, and durability. Manufactured from high-tensile steel or lightweight alloy, these subframes provide improved rigidity and reduced flex, ensuring consistent performance in both road and motorsport environments. Whether you’re performing repairs, chassis restoration, or performance upgrades, our rear subframes deliver the structural integrity your Porsche deserves.
What Does the Rear Subframe Do?
The rear subframe acts as a mounting structure that connects the suspension and drivetrain to the vehicle body.
Core Functions:
• Supports rear suspension arms, differential, and drivetrain mounts.
• Maintains accurate suspension geometry under load.
• Distributes forces from cornering, braking, and acceleration.
• Reduces vibration and road harshness through the chassis.
• Improves rigidity and alignment stability for precise handling.
A properly aligned rear subframe keeps your Porsche balanced and composed, ensuring every component performs as designed.
Why Do Rear Subframes Fail or Degrade?
Despite their strength, rear subframes are exposed to high stresses, corrosion, and impact forces — all of which can lead to fatigue or structural weakening.
Common Causes of Failure Include:
• Corrosion or rust weakening metal integrity.
• Cracks or distortion from high-impact loads or collisions.
• Worn mounting bushes causing excessive movement or noise.
• Metal fatigue from performance or track use.
• Improper alignment or installation after suspension work.
Failure can cause instability, poor alignment, vibration, or uneven tyre wear — all of which compromise your Porsche’s safety and handling.
Why Replace or Upgrade Your Porsche Rear Subframe?
Replacing or upgrading the rear subframe restores suspension alignment and chassis rigidity. Performance subframes improve geometry retention and reduce flex, offering sharper handling and more predictable performance.
Key Benefits:
• Restores correct alignment and rear suspension stability.
• Increases chassis rigidity for improved feedback.
• Eliminates vibration and rear-end instability.
• Available in performance-engineered and corrosion-resistant finishes.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Cayenne, and Macan models.
• Perfect for servicing, restorations, or performance suspension builds.
Design911’s Porsche rear subframes deliver precision, strength, and durability — ensuring your Porsche remains responsive, safe, and dynamically balanced.
Highlights
• Premium Porsche rear subframes and upgrade kits.
• Precision-engineered for structural rigidity and alignment accuracy.
• Constructed from high-tensile steel or lightweight alloy.
• Restores handling precision and reduces unwanted flex.
• Ideal for both road and motorsport applications.
• Suitable for servicing, restoration, or performance upgrades.
