Cool! Good to know.. I'm also going to be same as Jonathan.. just front rear strut and cat back... How about suspension? just spring and struts? And how about if I kept it Mazda (Mazdaspeed)?? I was always curious if that would be consider OEM?

Shocks are free in stock class (meaning you can change them as long as they use the same attachment point) but springs are not.

Parts are not consider OEM unless you order the car from the factory with them on, dealer installed parts don't count. So a Mazdaspeed 6 could run in the stock class, but putting a Mazdaspeed PPF on a RX7 would bump it to street prepared.

Hope this helps,
