I haven't had the patience to test tire wear. If it is infested with the
same bug as the RF temps, then presumably the RF wear would be higher as
well. If it isn't, then tire wear would certainly be the preferred way to
set up the car for longer races.
Could I talk you into sending me a few of yer roadie setups?
