Big Brake Kit

Larger rotors and multi-piston calipers from Brembo, StopTech, or Wilwood increase the thermal mass of the braking system — meaning it can absorb more heat before fading. A big brake kit doesn't necessarily make you stop shorter in a single panic stop (tires are the limiting factor there), but it makes you stop consistently on lap after lap. The larger rotor also moves the caliper farther from the hub, improving leverage. For anyone doing track days, autocross, or spirited mountain driving, this is a safety mod as much as a performance one.
