Excel-G's are a fixed-dampening shock with a price that's a little lower than the adjustable models. (They're slightly firmer than stock shocks, though not by much.) And they're available in specific sedan and wagon versions!
Note that these have traditionally been called "GR-2," but KYB recently renamed them. So now they are Excel-G. Same product, just a different name.
Set of four struts/shocks. Fits all 2004-2007 Subaru WRX wagon.
