The TEIN Group N damper was developed through vigorous testing in the P-WRC. TEIN's extensive background in Rally racing not only as a parts supplier but as a former team have culminated into the Gr.N damper. Some of the basic features include full-length adjustability, 3+1 - way damping force adjustment, external reservoirs, and inverted mono tube design. TEIN's latest technologies have also been incorporated which are Micro Speed Valve, Temperature Compensating Valve, and Hydraulic Bump Stop. Gr.N damper has been tested all over the world, and is currently used by competitors in P-WRC, China Rally Championship, Asia Pacific Rally, Polish Rally Championship, Africa Rally Championship, and Rally America series.
