The struts were changed different model years for the STI with different valving, however, it is my understanding that the spring rates and heights stayed the same for all the model year STI's which is why nobody tries to swap stock springs between model years. It is interesting that Prodrive and Tanabe both changed spring designs for the 2005 and later model year STI because the struts have less travel and don't work well with dramatic height drops.

Yeah I knew that the 04STI has something like that but was not sure. I know that the 07s have a 19mm because I measured it the other day when I was installing a catback system on our 07STI. I think that all these small changes make it annoying for us. :P
