Yes, this can be done quite practicle, but all the street driven IT cars I have seen eventually get modified so that they are no longer suitable for street driving. Once the rookie driver gets some seat time and gets to be a decent driver, they all want more SPEED. Thus slowly modifying their street rides to get that .5 sec. faster lap times. By the end of the summer, they have +600lbs springs, etc. that makes for a very crappy street ride. Cut to the chase, buy a $1000 Civic to get to work and then concentrate on your IT car. Or better yet, buy a low-end IT car and build it better. Keep in mind, you will probably throw twice as much $$$ into your existing car that to go out and buy a low-end IT car already built.
