i have an rs4 evo3, it runs good, can be tricked out for show or race. ihave some allum. part on my car. if you are wanting to race its not bad,parts are easy to get. i like my car ,it runs good and handels smooth. i run on a concrete track,i can run with the leaders without a problem. ther are better cars out there, it depends on how much money you want to spend. as far as tires you need to see whats being run at your local track.
