Not necessarily. A very aggressive driver could use up a set of stock pads on the track in one day. But usually starting track drivers are not using anywhere near the limit of the car on first track days and their wear on the pads is usually very light. But as you get more track experience you may find that more aggressive pads actually last LONGER than stock pads, because they are working in the temperature range they were designed for, whereas you may get beyond the intended temp range of the stock pads and see faster wear.
My suggestion for first upgrade would be our Hawk HPS pads
....which is a mild upgrade, that's what we run on my wife's car as she is learning to autocross and track drive. My own choice for street/autocross/track is our Porterfield R4
but that's barely streetable and you should expect some noise and dust. Also consider stock brake line upgrade to our Technafit MX5 Brake Lines
to take some more squish from the system.
