I gotta say the gt500 needs rubber!! 2.2 60 ft times are bad, 12.11, seems a little slow, i bet you his trap speed is very close to 130. I hve seen these cars run well in the 10s at 135+ stock, but with slicks,and a good driver!! Lethal performance has a 13 gt5oo in the nines already. (open headers,slicks, and a good tune) with trap speeds in the 140+ range.
