What is included in the Z-51 that is not in the ZF-1 ? I know it is things like dry sump oiling but is the performance exhaust also included in ZF-1? (it is in Z51 for 2015) Anyone know exactly what the comparison is in terms of features? If I am correct the price difference is $5000 forZ51 VS $1995 for ZF1 but what exactly does that extra 3000 get you? I do know that he Z51 includes performance wheels, tires, wheels, closer gear ratios, bigger brakes, dry sump oiling, etc........... Perhaps my question is really what does $1995 for ZF1 get you?
