We offer OEM rebuilt and revalved struts for your 2004 and 2005-07 Subaru Impreza WRX STI. These rebuilt struts will outperform your original struts.
We can also custom tailor struts to your after market springs and or driving style/needs at no extra charge. You can mail back your old STI struts for a $600 core refund; however, if your old STI struts have damaging corrosion or are damaged beyond repair, we may not be able to issue a full refund.
Revalve Service ($520 + $600 core fee):
- Cleaning and re greasing strut housings (eliminates strut clunk)
- Polishing out nicks and glazed spots from insert surface (long term reduction of strut clunk causing friction)
- Revalving inserts (improves ride quality over stock)
- High performance motocross grade shock fluid and nitrogen recharge (less change in ride comfort in cold weather)
- *Installation of Zerk fittings ($20 extra)*
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.
Set Up Options:
- 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 noticeable ride improvement driving on rough road surfaces as well as on 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 struts 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.
You can also choose to ship your struts in for the service ($520):
