I, too, would like to hear about this Forgestar issue. I assume you guys have experienced it with 19" wheels, since their 18" wheels aren't available yet. This concerns me because I bought a set of 18" F14s strictly for track use, but am waiting for them to be delivered. Those of you claiming they weaken the wheels, have you actually broken a wheel? If not, how do you know the wheel is jeopardized?
