I used to be convinced by the claim that a sport car is there to be seen, not heard! I didn't imagine how miserable I was with the stock equipment. I may need more time to formulate an objective opinion, but there are some first impression thoughts I may need to (must) share with somebody.
I have driven a variety of sport cars, and this is the first time a car feels like a jet plane. Describing the moment I tried the kit the first time, the feeling was as if I am taking off a fighter jet!
