Bigger brakes don’t really feel much different during normal driving. But when they heat up and on track or aggressive driving they make a difference for brake fade.

They are fine for my needs. It’s more for looks since I got big wheels. They design of the 2-piece is stupid with the rivets instead of bolts. If they had bolts like aftermarket BBK and make the rings replaceable, it would have saved them tons from the TSB. Most people replacing the rotors later are installing solid $50 rotors anyway after they realized the 2-piece are $250/each.
