Racingline USA’s Seventh Generation GTI to Debut at Waterfest Share Comments Racingline USA will be displaying their MK7 GTI for the first time this weekend at Waterfest, featuring a host of Volkswagen Racing upgrades. The modifications primarily focus on improving driving dynamics, with aftermarket Springs, Sway Bars and End Links, a big brake kit and lightweight wheels. Power has also been increased through use of a Volkswagen Racing 3″ Exhaust and Prototype Intake. A closer look will also reveal the use of OEM Golf R tail lights. Our source at Racingline tells us there is much more to come with this car during the next 12 months.
