Solid subframe bushing set. 12 bushings in kit. 1 kit req'd per car.

Fits:
Porsche 996 / 997

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.

Cartridges install easily to replace rubber bushings for 996/997/Boxster/Cayman. An excellent alternative to our QuickChange Camber Plates for cars that don't need more camber but still want the handling precision of a spherical bearing monoball. Spherical bearings improve performance. The spherical bearings pivot freely, but eliminate the deflection that is inherent with the factory rubber bushings.

Eliminating Deflection Is Important For Two Reasons

• The factory rubber acts as a spring in series with the strut. This rubber spring-action is completely un-damped and reduces the struts ability to control the tire contact patch. The spherical bearing allows the strut damper to do its job and control the contact patch.
• The factory rubber deflects sideways under cornering loads, causing loss of camber just when you need it most. Our spherical bearings eliminate the deflection, maintaining stable and predictable camber.

Rennline Strut tower brace - 2 point. FRONT.

Fits:
Porsche 986 Boxster 1997-04
Porsche 996 1998-05

One of the easiest and most cost-effective ways to improve your car's handling is the installation of a Rennline strut tower brace. These braces bridge both shock towers, eliminating virtually all camber change that occurs during hard cornering. Not all cars are the same, so Rennline has made their braces fully adjustable, allowing you to set a desired amount of pre-stress. Both the strut bar and brackets are constructed from aircraft grade aluminum, and include stainless steel hardware. Rennline strut tower braces bolt in and out in minutes and require no drilling. Whether you're on the street or on the track you'll feel the difference immediately. This strut brace does allow the use of your plastic cowl cover.

When lifting a 996 chassis, the extra height required for taller tires will increase axle geometry. Adding a subframe drop will improve axle performance and longevity. It will also allow for more suspension travel and relocate control arms for better geometry. 

Designed for Porsche 996 Overland/Safari projects. 

Spacers are CNC machined from 6061 billet aluminum then gray anodized for protection. 

Hardware is 10.9-12.9 custom built from scratch. No universal threaded rod. All zinc coated for lifetime of corrosion resistance.

About Suspension Upgrades

Porsche Suspension Upgrades & Components

Your Porsche’s suspension is the key to its handling, comfort, and safety. Upgrading or maintaining your suspension system not only restores factory performance but also unlocks sharper cornering, improved ride quality, and greater driver confidence.

At Design911, we supply a complete range of suspension upgrade parts for Porsche, including:

  • Anti-Roll Bars
  • Control Arms
  • Lowering Springs
  • Drop Links
  • Strut Mounts
  • Polyurethane Bushes
  • Engine / Gearbox Mounts

We stock world-renowned performance brands such as DesignTek, Bilstein, Ohlins, Koni, Powerflex, H&R, KW, and Nitron, trusted in both road and motorsport applications

Why Upgrade Your Suspension?

  • Improved Handling – reduce body roll, sharpen steering response, and corner with confidence
  • Better Ride Quality – balance comfort and control for road or track use
  • Increased Durability – high-quality components outlast standard rubber parts
  • Performance Customisation – tailor ride height, stiffness, and response to your driving style
  • Safety & Stability – maintain consistent contact with the road under all conditions

Key Suspension Components

Anti-Roll Bars (Sway Bars)
Reduce body roll during cornering, keeping your Porsche flatter and more stable. Perfect for spirited road driving or track use.

Lowering Springs
Improve handling and aesthetics by lowering your car’s centre of gravity. Can enhance steering precision while giving your Porsche a more aggressive stance.

Drop Links
Connect anti-roll bars to the suspension arms. Upgraded drop links ensure accurate movement transfer and eliminate play that can develop in worn components.

Strut Mounts
Provide the critical connection between the suspension strut and chassis. Replacing tired mounts restores steering accuracy and reduces knocking noises.

Polyurethane Bushes
A performance upgrade over standard rubber bushes. Poly bushes (such as Powerflex) offer increased durability, sharper response, and reduced flex under load.

Engine Mounts
Help stabilise the engine under acceleration, braking, and cornering. Upgraded mounts reduce drivetrain movement, improving handling feel and gear change precision.

Common Signs of Suspension Wear

  • Knocking or creaking noises over bumps
  • Excessive body roll or poor cornering stability
  • Uneven tyre wear
  • Steering feels vague or less responsive
  • Ride height appears uneven
  • Vibration or harshness through the chassis
