Improved Handling and Precision
Our Rear Subframe Solid Bushing kit improves handling and precision by providing geometry correction for lowered cars and eliminating deflection. Porsche recognizes these performance benefits and uses a similar solid rear subframe mounting approach on the latest GT3 street and Cup racecars.
Replaces stock rubber bushings in the rear subframe of the Porsche 996 and 997 cars, raising the subframe into the chassis 6.5mm (.25 inch).
Geometry Correction
Lowering the 996/997 provides the benefits of lower center of gravity and improved appearance. Unfortunately lowering also causes the rear suspension members to angle down as the inner links drop with the chassis and the outer links remain at wheel upright height. This downward angle harms performance.
With the suspension members angling up towards the wheel the Roll Center is lowered which causes increased chassis lean, toe and camber curves are shifted and become less optimal, static toe and camber adjustments are shifted often exceeding the range of the stock adjusters.
Our kit raises the rear subframe .25 inches (6.5mm) to help reverse the negative effects of lowering. Suspension member angles are improved and performance is enhanced. Our upper bushing fits inside the subframe, eliminating the entire thickness of the upper rubber bushing for the greatest possible geometry correction achievable from bushings alone.
Eliminate Deflection
Stock rubber bushings compress and deform under heavy cornering, braking, and acceleration loads. The compliant rubber bushings allow the entire rear subframe shift about relative to the chassis. Rear camber and toe settings wander along with the subframe making the car less predictable, less stable in turns.
Our solid bushings replace the compliant rubber and do not deform under cornering loads, keeping the subframe in position and alignment true even under heavy cornering loads. The car becomes more predictable and easier to drive fast.
Build Quality
Each bushing consists of two pieces, an upper plug and lower puck. The plug is machined from solid aluminum with knurled edges for perfect fit.
Lower puck is machined from solid steel with zinc finish for protection.

Porsche Suspension Side Section / Subframe | Design911 Structural Components for Strength, Alignment & Stability
The suspension side section or subframe is one of the most critical structural elements in your Porsche’s chassis. It provides a rigid foundation that connects the suspension arms, steering rack, and drivetrain components to the vehicle body — maintaining alignment, stability, and precise handling. A solid subframe ensures the suspension geometry stays true under load, delivering predictable steering response and confidence-inspiring control at all speeds.
At Design911, we offer a complete range of suspension side sections and subframes, engineered for precision, durability, and strength. Manufactured from high-grade steel or aluminium, these components provide the rigidity required for both performance and safety. Whether you’re carrying out repairs, restorations, or performance upgrades, our subframes and side sections restore your Porsche’s structural integrity and suspension alignment.
What Do Suspension Side Sections / Subframes Do?
The subframe or side section acts as a structural mounting point for major suspension and drivetrain components. It absorbs stresses from braking, cornering, and acceleration while maintaining chassis alignment.
Core Functions:
• Supports the suspension arms, engine mounts, and steering assembly.
• Maintains precise geometry for accurate wheel alignment.
• Distributes load evenly through the chassis for stability.
• Reduces vibration and harshness for a smoother ride.
• Enhances handling balance, safety, and structural strength.
A correctly fitted and aligned subframe ensures your Porsche handles with precision and performs safely under all driving conditions.
Why Do Suspension Subframes or Side Sections Fail or Degrade?
Even though subframes are engineered for strength, years of stress, road conditions, and exposure to the elements can cause damage or deterioration.
Common Causes of Failure Include:
• Corrosion or rust weakening the metal structure.
• Cracks or deformation from road impacts or collisions.
• Fatigue from long-term stress and vibration.
• Worn mounting points causing alignment issues.
• Improper repairs or installation affecting structural integrity.
When a subframe or suspension side section fails, it can cause uneven tyre wear, poor alignment, steering instability, or suspension noise — all of which compromise safety and handling.
Why Replace or Upgrade Your Porsche Suspension Side Section / Subframe?
Replacing a damaged or corroded subframe restores chassis strength, alignment accuracy, and handling performance. Reinforced or upgraded components offer improved rigidity for demanding driving conditions.
Key Benefits:
• Restores proper suspension alignment and structural balance.
• Improves handling stability and steering precision.
• Eliminates vibration, flex, and unwanted movement.
• Manufactured from corrosion-resistant, high-strength materials.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Cayenne, and Macan models.
• Perfect for restoration, servicing, or performance-focused upgrades.
Design911’s Porsche suspension side sections and subframes provide exceptional engineering and build quality — keeping your Porsche stable, responsive, and ready for the road or track.
Highlights
• Premium Porsche subframes and suspension side sections.
• High-strength steel or aluminium construction for rigidity.
• Precision-engineered for accurate suspension alignment.
• Restores handling precision, safety, and comfort.
• Compatible with both modern and classic Porsche models.
• Ideal for restorations, performance upgrades, or crash repairs.
