You can expect 1st gear to be VERY short and way torquey. Giving the throttle the least bit of gas without laying forward will loft the front very quickly. Otherwise, you'll probably enjoy the frightening amount of acceleration that combo gives. You'll go from 0-137 REALLY QUICKLY. Btw, 137 was the top speed before redline with that gearing on my 03S3.
I've since switched back to the stock front sprocket for street riding and I'm saving the 17t front for trackdays and other times I want to go REALLY FAST, like going up to Milan drag strip.
