Okay, so they can crack the 15's, hehe, they are a match for the 305 RS Slowmaros of the time.
Car to car no Probe GT will not hang with much of anything as far as a Mustang V-8 goes. That excludes drivers from the scenerio.
As far as a 300ZX TT, they don't have a prayer if it was the 90 and newer models. Those cars run much like a DOHC Cobra.
