A word of caution on the IROC Z 28s in that era--------there were some that had speedometers that only went to around 80-100 and there were some that went to 160?------various reasons------the tires that were ordered on the car effected the speed that the GOVERNMENT would let the MANUFACTURERS set in the computer and also there were numerous options on brakes-------if you have disc brakes all around and a speedo that is higher mph, your brake valve, master cylinder,etc, will be different from a pokey 85mph polictical correct car-

Sooooo----whats your speedo and brake system ????
