GT30r’s are small. If i’m not mistaken, an FP green or red is acctually larger. I know my 60 trim was 54#/min, and it was larger then a 30r.
edit: I see that they say GT30r’s can support 500 horsepower, so maybe it is the same as the FP series, or similar. I was thinking it was much smaller, but I was probalby thinking the specs of a 28r.
