Advice on 2021 Impreza brake upgrade

[d1.penney]

I'm considering doing serious brake upgrades for my 2021 Impreza Hatch, and I'm looking for some advice to make sure I do this right. I just got my hands on a set of 4-pot front calipers and some sport rotors that are supposedly the same size as the fronts from a 2006 WRX. I drive this car pretty hard on the weekends, especially on those twisty mountain roads around here, and my biggest fear is boiling my brake fluid. It's happened to me before in other cars, and I definitely don't want that kind of scare again. I'm looking for recommendations on a good medium-high temp brake fluid that you guys swear by. Something that absolutely won't boil under hard driving conditions. I'm also open to suggestions for ceramic carbon pads and rotors to complement this setup. Durability and fade resistance are key for me. I'd appreciate any tips!

For fluid that won't boil, Endless RF-650 or AP Racing R3 are top tier choices with insane dry and wet boiling points. They're pricy but perform.

Motul RBF 600 or Castrol SRF are good brake fluids cos they both handle high temps and resist boiling really well under hard driving. As for rotors, stick with slotted or drilled rotors designed for track use

You got some good advice about specific models, but let me throw in something that you shouldn't forget. With these kinds of upgrades, you have a few things to keep in mind. Upgrading the rotors and calipers means you'll need to make sure your wheels are clearing them. If they don't you'll need to upgrade the wheels as well. Also, while you're at it, don't forget the brake lines.
