I don't race USGT (for now) but this is a good thing IMO. Many of you probably have used Solaris tires for USGT and have plenty of sets in your bag, I have 6 sets myself from racing 17.5 TC.
A set of Solaris tires are approx $28 per set, Gravity tires are $13.99 per set. Remove the old Solaris tires, glue on new Gravity tires ... VOILA !! you just saved yourself $14 !! Multiply that by number of old sets in bag, in my case 6, I just saved myself $84 !!
There's several race day fee's. Gas to and from track. New bodies. etc, etc ...
