I have a chance to pick up some springs from an 04 STi and put them on my 04 WRX pretty inexpensively. Does anybody think this is a good plan? Does anybody know what the drop rate would be on these? Would there even be a difference? Would they even fit on stock WRX struts? Or should I just buy some Prodrive or Tein Springs? I appreciate the input.

 

Njc200: I don't think there would be an issue with fitment on the 04 WRX as the STi and WRX are both GDB chasis. But you shocks will definately be underdampened for the STi springs. You will have to either buy STi shocks or aftermarket ones to match them

Squeech: There will be an issue with you having to probably use 04 tophats to make them fit. Also the GDA and GDB chasis are a little different and the STi spring rates for the two chasis are different .... to compensate for weight and geometry distribution .... probably not a good idea ....

 

dude you're wasting your time just get some STi take-offs (bolt-on strut & spring) from Gruppe-S...

you'll be so happy its not even funny.
