I know that the GRP's are much cheaper off of retail and retail GRP vs Jenny's Hoons is closer in price but I was wondering it there was a avenge with the Hoons over the GRP's. and are the GRP's rated for higher speeds? to me it seams that way Hoons are rated for 150 and people are running there GRP's to 170, and then they shred. I would be running them on a Felony (same diff gearing on both ends).
