Subaru Impreza STI GDB AL+ Pro Coilovers
AL+Pro is based on our popular GR+Pro model. AL+Pro features full aluminum shell construction which has excellent anti-corrosion characteristics for customers that see extreme weather conditions. The aluminum shell casing is also lighter than steel, providing less unsprung mass for greater response. The helper spring allows the shock piston to be placed in the optimal position within the shock body, increasing rebound stroke, and maximizing articulation on cars with minimum suspension travel.
Spring Rate is 8K/6K. Includes front and rear camber uppermount, inverted front and rear shocks, front and rear helper spring.
