What made you think the WRX was stock? I would think it had at least some tires considering the way it was being driven. The stock Potenzas (is that what they still come with?) are terrible. The race was back and forth the whole time. There were parts where the vw was quicker and parts where the wrx was quicker.

Please sell your vw. You aren't even willing to try and make it "faster". It can be made into a great car (performance and looks), but since you have already convinced yourself that it's a horrible car that's all it will ever be to you. That is obvious by your comments on the video...
