|These are OEM rebuilt and revalved struts for your 2004 Subaru Impreza WRX STI. They will out perform your original struts.
The Revalve Service that we perform to the STI struts includes:
What the heck are Zerk fittings for? We strategically place this fitting between the strut's bushings. This now allows you to add fresh grease to your struts without removing them from your car! When grease is worked away from the strut bushings, the strut begins to clunk. By applying more grease via a Zerk fitting, you create grease pressure between the bushing and fill the dry spots. Your set up the options explained:
Tarmac Spec (most popular)- Great for high spirited driving utilizing the original or aftermarket springs. "Tarmac Spec" offers a more compliant and balanced ride over stock. There is a noticeble ride improvement driving on rough road surfaces as well as tighter curvy roads.
Gravel Spec- This is ideal for those who participate in Rallyx or demand more performance on gravel. Gravel spec valving is harsher at low vehicle speed, but resists bottoming at higher speeds and big ruts. There is more high speed rebound damping to control rebound speeds after the sturts get close to bottoming. We do not recommend this spec for daily driving.
Custom Spec- This is for those who have dedicated their cars to a specific use such as road racing or just want to run a spring rate that is much softer or stiffer than the original spring rate.
