2012 ES 350 72k miles. Braking is sufficient but that's all the credit I can give it. All rotors/pads/fluid/calipers are in great shape or were recently replaced. Was just wondering if there was an easy swap to maybe IS/GS calipers and rotors to help get a more confident braking experience. I've come from a string of performance oriented vehicles so I realize I'm a little spoiled. Thanks for any input.
