Would agree if you want multi use that the RE71 is a good chioice ---sure can't drive on the street with Pirellis,ha? HR692 , you should also find out how quickly tires wear at the track you intend to run the most ---- VIR, Summit Point,NJMP? Some tracks will eat tires quickly, whereas others can be super easy on rubber. Heartland Motorsports Park ( Topeka, Ks. ) was repaved less than two years ago and tires there seem to hardly wear at all - I got virtually 3 weekends on used Pirellis. Hopefully gathering all this info will help you decide on what you want to acquire for tires? Assume you are getting a second set?
