I would spend hours cleaning my 2016 ATS-V from top to bottom. With standard brake pads, the wheels are littered with brake pad residue three days later. I installed these pads (easiest pad install I've ever done) and BOOM installed. No more dirty wheels! Two weeks without a wash and my front wheels (mine are polished) hardly show any marks. It's really a day/night difference. For $65 and an hour or two of my time to install it. Does the power supply stop after installing these pads? My car stops for a dime. Are they better/worse than stocks? I can't tell you that without a test drive. I can tell you that I worry about people following me because I know they can't quit as fast as I can. I give these pads a full 5 stars and would even give them 6 as I haven't felt any loss of braking power and after a few days of riding the wheels are clean now. Do that!
