Bearings Bushings- Solid Subframe Bushings Kit (1 Kit Per Car)) 996,997 1999-2012


***EVERY ORDER IS REVIEWED BEFORE SHIPPED AND IF YOUR PURCHASE  IS FOR MORE THAN ONE PART EXCESS SHIPPING IS REFUNDED TO YOUR CREDIT CARD OR PAYPAL ***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 cars, raising the subframe into the chassis 6.5mm (.25 inch).

Geometry Correction

Lowering the 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.

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.

The kit includes 12 bushings. Order 1 kit per car.

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
