BC Racing Coilovers Acura RSX & Type-S (02-06) BR w/ Front Camber Plates / Swift Springs

BR Series: This suspension system offers 30-clicks of compression/rebound adjustment, has independent spring preload from height adjustment, uses a linear piston and has a linear damping curve (force vs velocity curve). The BR Series is our best seller as it’s well suited for daily driving and can easily be customized with with different spring rates, damper lengths for stance/show cars, and custom valving. The versatility of the BR Series really allows a user to start out basic and then progress to a more competitive setup later down the road, if desired. Or the kit can be spec’d as desired right from the start and we can build a custom kit with the desired specs.

DS Series: The DS Series uses a digressive piston and gives a digressive damping curve. The major benefit of the DS Series is the increased low speed damping force that is exerted by the damper when the piston travels at less than 50mm/sec. This translates into a more visceral driving experience because the increased low speed compression force is more of what the driver “feels” when they’re driving the car. For example, increased low speed compression force would be most noticeable when braking before a corner from a straightaway, going through tight s-turns, or aggressively attacking a nice tight twisty mountain road. The DS Series offers all the same customization as the BR Series, with the benefit of that awesome digressive piston. They also have a cool matte silver chrome finish. The DS Series is more track specific than the BR Series, but it super compliant and comfortable on the street, in my opinion. It also offers 30-clicks of simultaneous compression/rebound adjustment, height adjustment independent of spring preload, and can be customized with different spring rates, damper lengths, and custom valving.
