Description
PROGRESS is proud to offer our specialized expertise in design engineering and manufacturing, to companies interested in developing new suspension products or redesigning existing components. PROGRESS draws upon over 30 years of combined experience in the design, manufacture, and tuning of performance suspension systems, including CART/Indy Cars, IMSA, SCCA, NASA, and SCORE competition vehicles. We are enthusiasts, and our products represent the result of our engineering and manufacturing expertise.
Sport lowering springs will significantly improve appearance and handling capability. Increased spring rates improve handling by lowering the center of gravity and reducing body roll, and the progressive spring rates help for a superior ride quality. These springs are designed to work with OEM shocks but will benefit from using high performance shocks such as Tokico, Bilstein, or Koni. Our engineering staff has decades of experience in the design and tuning of performance suspension systems, including CART/Indy Cars, IMSA, SCCA, NASA, and SCORE competitors.
The culmination of all these factors allows us to provide our customers with the ultimate goal: Quality domestic built proven performance suspension products at a great value and a limited lifetime guarantee to boot.
Because of multiple bends in a stock replacement anti-roll bar, it is difficult to calculate the rates. Most manufactures calculate the rates then check the actual rate of the bar mechanically. Adjustable anti-roll bars have multiple mounts on the arms to change the arm length and therefore the bar rate.
