Meisterschaft Motor recommends the Toyo Proxes RA-1's for anyone looking for a consistent set of R-compound tires under a wide array of usage, whether you are a driver school student, weekend track warrior, or competitive club racer.  We have found these tires to offer amazingly good wear characteristics, yet offering great grip for the most serious competition use as seen in SCCA World Challenge events.  These tires are a great alternative for driver school students instead of tearing up a set of expensive street tires.  The RA-1 offers the gradual break away characteristics of street tires at their limit of adhesion, which is important for novice track event participants.  These tires are shaved to 4/32 and were single track heat cycled in race qualifying, they are ready to be mounted and hit the track!
