Got 5.0? We do! In fact Lethal Performance currently holds the record for the quickest 2011 5.0L GT using the stock MT-82 transmission. The 2011+ 5.0L mustang is without a doubt one of the best mustangs ever built. With their high flowing 4v heads, independent variable cam timing and it's high compression these car react very well to performance modifications. Start off with a custom tune from Jon Lund and a JLT Performance intake and you're already stepping over 400rwhp. Add an offroad X or H pipe and you'll pick up another 15rwhp. If better sound is what you want a Magnaflow, Borla or Bassani catback will definitely liven things up. For those looking to take it to the next step we offer several different supercharger kits from Whipple, Vortech, Procharger and Roush. In order to handle big power a clutch upgrade is definitely in the forecast. For this we chose the Mcleod RXT twin disc setup which is our best selling clutch setup. However other clutch kits such as Mcleod'sr RST or any of Spec's offerings work very well. To put all of the power to the ground you'll definitely want to look into some suspension mods. UPR, BMR and Steeda are all excellent choices and will help improve traction and handling. Most people start out with some upper and lower control arms followed by a panhard rod and brace.
