In my opinion the RE71R is an excellent tire but not the best choice for a novice. I have seen a lot of students at Evo schools this year who developed bad habits from driving on it.
Go with the V720 or the Federal 595RSR. Spend the extra money on getting more seat time, working on your driving, and having fun. When you get good enough that you are within a second of the fast guys then it's time to start making sure your car, mods, and tires are the best available.
I will promise you this if you buy the V720, Federal 595RSR, or RS3 they will not be the limiting factor holding you back!
