Rear Sub Frame
Fits:
Porsche 944
Porsche 924
High Density trailing arm bushings for the 944 and 924s can both eliminate clunks from failing factory units and restore proper suspension geometry in your street or track car. Featuring an increased stiffness of 25% over OEM parts (90133102101), these are the ideal replacement for either failed or aging stock rubber units. These bushings locate rear trailing arms better under the sustained loads often experienced on track and in the rigors of everyday driving.

What This Product Does:
Trailing arm bushings support the rear suspension’s trailing arms—these are the suspension arms that locate the rear wheels fore-and-aft (controlling longitudinal movement) and maintain alignment under load.
The “heavy-duty” or performance version of the bushing set:
Symptoms / Signs You Need Replacement:
- Rear-end clunks, knocks, or “trailing arm slap” over bumps
- Wandering or instability in the rear under braking or cornering
- Poor handling or vagueness in rear responses
- Uneven tire wear on rear wheels
- The rear may feel loose, sloppy, or disconnected under load
Why Upgrade To Heavy Duty Bushings:
- Sharper Handling & Feedback – Stiffer material minimizes unwanted flex.
- Improved Alignment Retention – Keeps toe and camber consistent under load.
- Enhanced Stability – Increases rear-end composure at speed and in corners.
- Long-Lasting Performance – Heavy-duty rubber resists aging and deformation.
- Ideal for Performance & Restoration – Perfect for spirited road driving or track setups.

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.
