When it came to 60-0 braking, the results were stellar at 112 feet. Even more impressive was the fact we were able to drop that to 104.5 feet by simply swapping over to the new tires. Out of the factory, the Z06 came with P265/40ZR17s. Not available in a 265, we stepped up to a slightly larger size: P275/40ZR17. We attributed the reduced stopping distance to the wider contact patch and stickier tire. And to think, we haven't even played with the brakes yet!
