While looking throuh japanese Impreza wrxSTi mags. and catalogs, I notice that there are two different set of bbs wheels. one STi and one STi spec C. basically the difference was that at the end of each spoke where it meets the rim, the spec C has an extra piece cut out I guess for weight savings. guess which one we get? thats right the spec C!!!!!! BABY!!!! wish I had a scanner to show you guys. by the way, I got my white with gold on the 27th at msrp from Irvine Subaru.
