I'm trying to get some Tein H techs for my Legacy but there is some conflict with the chassis code. My car is a 2003 Legacy 2.0i (JDM model) with a BL5 chassis code but everywhere I check I hear they only have the springs for the BL9 (USDM model). I don't want to spend the money only to find out the springs wont work. Does anyone know if there really is a difference?
