2013 ford shelby gt 500

can someone plz help me upgrade and tune my 2013 ford shelby gt 500 for drifting

You can check the Drift Lounge in the forum and also there are a couple of tuners (ex. DIS Swirly and others with YouTube videos) that could help. The GT500 is a beast to tame, I have it drifting at times yet not intentional so hopefully you won’t have a problem and will enjoy it. Good luck!
