IMO, i think R&T simply took the Subaru front end and put it on a GT86 picture and a made a few simple changes
if you also noticed in their poorly written article they placed the height at 56", again way off
Other than having the wrong height, I don't see anything else wrong with the article, which is just a first glance review and not an in depth full review.
15.5:1 compression ratio is really high in a production NA engine let alone one with a turbo. Manufacturers usually lower compression to turbo charge an engine. In the FA20's case, I'd suspect a 9-10:1 ratio before turbo charging becomes a viable option. Stock is going to be 12.5:1 I believe, which is why premium fuel is going to be required.
I can do without the spoiler. Deck spoiler is all I need. Carbon roof would be nice, but I don't see this happening for cost reasons, even on an STI. Unless there's some new fangled way of cheaply integrating carbon fiber that Subaru has developed.
