If the "global economic downturn" continues to limit my project for the WRX I plan to run in the Stock Class this year. I was sifting through the rules and I'm a little confused about something. Unless I read it wrong, it seems that one can use any factory parts, from any trim level, that were available for a chassis. I have heard of the Civic and Neon guys doing this but the rules are a little hazy on the subject.

If this is the case I'm thinking of running STI shocks and springs on my WRX this summer.

Can anyone offer some clarity on this?
