The early air-cooled Porsche 911 systems is the signature damper system from Motion Control Suspension.

Racing Shocks Australia is the Australian importer & factory trained service dealer for Motion Control Suspension. MCS is a boutique manufacturer of vehicle damper systems.

These 911 struts/shocks systems are used regularly in Australia on Street/track day cars, Targa Rally vehicles & Internationally in Safari style rallies as popularized by Lehman Keen in the Keen Project You Tube videos. Multiple Le Mans winning driver Tom Kristensen has MCS dampers fitted to his Porsche 911 that was built to commemorate his very first win.

Motion Control Suspension has worked with the application regularly over the course of our 28 years and counting, know what it takes to make these cars handle well. Whether you are restoring your Air-Cooled Porsche, have a resto-mod build in the works, or if you race your car, with our help we have a solution for you.

Our dampers have threaded bodies and can be used with coil springs or torsion bars. Damper lengths are carefully designed for your vehicle, with consideration of your wheel and tire configuration, ride height, and goals; this ensures you have appropriate bump and droop travel, and not only meet, but exceed your goals.

These systems are available for early air-cooled engined Porsche 911's, including but not limited to:

• F-body series (1964-1974) including 912 models & the rare 912 E in 1976
• G-Body series (1974–1989) including 930 & Carrera models

Stock comes direct from the USA with a build/delivery time of 4 weeks for off the shelf production lengths & up to 10 weeks for custom/one off strut leg setups.

Twin spring setups use two springs per wheel, the smaller being a helper spring for road use or tender spring for track work which is normally completely compressed at ride height. The rate of the tender spring helps to keep weight on the inside wheel in cornering while giving additional roll support. Spring rates will be specified dependent if the car is only driven on the street, street & track or race only.
