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.

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.
