These RS-R are built to bridge the gap between street and track. They have the comfort of a street spec suspension but with the ability to perform on the weekend track days without question. They do this by catering the spring rates and valving to the vehicle specifically.
RS-R has been around since 1980, founded in Osaka, Japan, producing high performance and high quality products, focused on filling gaps in the suspension market. All of their coilovers are tested in different track settings depending on what they are made for, from drag racing to street racing to drifting. RS-R also actually tests these coilover kits on a dyno here in the USA.
