Your Fiesta ST came ready to rally straight from the factory. But if you’re driving it hard, it’s likely you’re also braking hard and may need new brake pads or rotors. You may also want to upgrade your hardware, especially if you’ve made major performance mods.
Stainless steel brake lines can help improve brakes' responsiveness. You can couple these with improved braking fluid for crisper brake feel in your Fiesta ST.
If you’ve already decided to change out your brake pads, you may want to consider changing your brake rotors. Usually you’ll want to replace them every other brake pad change.
