well for ford guys you sure are traitors, i would liek to know were you got the 11.90 et from bud, stage 3 roush---roots style blower-3.55-and a handling package=12.25 et. drag pack---roots style blower, with upgraded pulley, 18 psi of boost(over roush's 12-15) 3.73 gears, a stage 3 g-tec suspension and slicks. not 11.90's try 11.30's all day. if you dont run atleats really low 12's, get off the track, you cant drive. my buddy bought one of these and took a modded 06 z06. the warranty shit does suck, but your buying a race car. and for the record there will be 53 made this year. there are talkin about bringin them back next year if they do well. that 4.6 stays with shelby's 5.4 all day long. not trying to be an ass guys, but workin for ford you tend to know this shit. peace
