believe me(us), you won't need more than your typical pilot power or of equal value competitor's tire. to add to the above, a PP will last you quite some time and you can do many sessions on the track and on the street. if you were to get a power pure/1, sure you'd be good to go on the track, but how many highway miles do you do? those tires are medium compound center IIRC and you'll flat spot them in no time and will need to spend more money on another set of tires. stick with a good lasting street tire, and when you get into the game more and your skill level increases, get yourself a second set of rims and then you can have a dedicated track set of tires. or 7 sets waiting if you're like me...
