Are we looking at the same cars, cause the rear diffusers look different. If you look at the 2015 WRX's rear diffuser, it's the 2003 Spec C's rear diffuser with some fins.Granted they stole the rear diffuser from an Evo X but overall.
that's the most depressing thing in this threadAlso, I think some might be quite disappointed when the new STI comes out. I was hoping for the new FA20 turbo layout to also carry over on the STI, but that doesn't seem to be the case. The STI will still be a 2.5L. Unless Subaru designed a 2.5L FA (very doubtful), rumor has it, it'll be an "updated" EJ25 with direct injection and the front mounted turbo.
