Hey guys I'm new here. Thinking about buying a 13' GTS, possibly turbo. I'm curious on what are some normal upgrades you guys have done. If I get one I want to be able to make it a 4 second car. My current stable is 2010 RR Sport Autobiography(600Hp), RR Supercharged, 2016 Cayenne, 2007 Lamborghini Gallardo Spyder. Thanks guys!
