I believe the Ver. 8 has more agressive cams than the Ver. 7, and both Spec C's have more agressive cams than both the Ver. 7 and 8 regular STi's. Then there are the differences in the turbos....the Ver. 7 comes with a VF-30, the Ver. 8 is a twin scroll right? I think a VF-37, and the Ver. 7 Spec C, and I think Ver. 8 Spec C come with the VF-34....I could be wrong, this is just off the top of my head. Please correct me if I am wrong. Oh, and dont the Spec C's rev out to 8500 rather than the 8000 redline of the regular STi's? Hope this helps.
