The 2015 GTI is much improved over the previous gen- electronically controlled mechanical LSD (!!), 258 ft-lbs, front wheels 2" further forward, similar weight. I could easily see it ending up being the car to have for GS. That's the thing with Street classes, there will always be a new car that is faster than what you have. Solution: prep your car for STX where you can fix a lot of the things that hold the FiST back in GS!
