Considering I pay extreme attention while driving (to the point of ignoring people in the passenger seat and NOT answering my phone in heavy traffic)... my biggest worry is someone plowing in to me if I have to stop fast.

My stop distance one these cars is shorter than most. Just do a test yourself on a empty roadway where you can get up to 60 mph. Find a reference point and come to a complete stop as hard as you can from 60 mph. The stock stopping distance was targeted at a 60-to-0-mph stopping distance of no longer than 115 feet.

Mine stops better than stock now as I'm running R4 race compound pads and race fluid on cryo treated rotors.
