They are great with the currebt setup i have. My c8 is still sometimes out of control too much tail happy and sometimes not enough. Im 12 packs into them. The fronts are shot and have been runing bald for 3 packs. The rears still have threads left one tire seems to have axle wear but has less wear than the other tire. These tires aint cheap either. Im going to replace the fronts with the new grps.
