WRXTom Posted June 21, 2004 Share Posted June 21, 2004 A few suspension questions: 1. Can anyone provide detail on the USDM, Japan-spec and STi spring rates? 2. Are the USDM and Japanese struts the same spec? Also, if the answer to 2. is "no" then what will be the compatibility to USDM of the STi springs that are currently available in Japan? *edit* - and, if necessary, will STI make USDM specific springs. I realize it is early so we are just guessing at this point. Tom Link to comment Share on other sites More sharing options...

WRXTom Posted June 22, 2004 Author Share Posted June 22, 2004 I'll just copy and paste. Not sure what it means yet as far as options for USDM since our struts may or may not be compatible with these spring rates.

eavr4 Posted June 23, 2004 Share Posted June 23, 2004 Wrx Tom,....I also found I think is the ECU diagram for the USDM 25GT do you want? As I do not have USDM 25GT ECU I cannot verify however compared with the 20GT (JDM) diagram quite similer in most of the pinouts but most significant difference is the Cruise control pins...
