zo6's running about 33.5 to 34 something on hoosier a6's. I was running right at 36 seconds. Stock PS2s. Tires can bring about 2-3 seconds off your times. So its hard to tell. The viper is a lil difficult on autocross with the torque. It will understeer on tight corners. I lil throttle and it steers better, more throttle you get power oversteer. Im still learning the car. I think with tires, and camber adjustment it would be competitive. But like you said so is a miata. If anything you get a tremendous idea of how the car handles, and the back will steep out pretty quick.
