I used a Evo Rad suppurt on my GSR, I got a old 1/2 cut shell after it had been stripped for $100, was 2nd hand sure, but it did the job, panel beater just unpicked the rad support from the rest, had it sandblasted then fitted to my car, I'm sure it wouldnt have been $600 worth of work. He also unpicked the extra strut tower bracing sections and welded them onto my car. It also has the brackets for the genuine Evo front bar to bolt to near the headlights. I think the main difference between a standard CC one and a GSR one will be sections cutout for intercooler piping.
