The 5200 Competition Series for the 2001-2005 BMW 318d Sedan-Touring-Coupe-Convertible (E46) are 2-way adjustable shock absorbers which are based upon competition 3-way adjustable shock absorbers. The 5200 shock absorbers are adjustable in compression and rebound.
The design of the compression adjuster is an evolution of the compression adjuster we provided for the American Grand-Am series for the last few years. The 5200 shock absorbers were designed to achieve a quick and easy set up, allowing separate adjustment of compression and rebound.
The 5200 Competition Series AST uses an external canister. Throughout testing and competitions, the 5200 has been praised for its performance and capabilities, surpassing other major, more expensive brands and setting a new standard of 2 way damper. Its no surprise that the 5200 is fast becoming a favorite damper amongst race teams and track day enthusiasts world wide.
