The Goodridge G-Stop stainless steel brake line kit for 2016–2018 BMW M4 front brakes swaps OE hose for a PTFE inner with stainless overbraid. Upgrading to -03 PTFE hose sharpens pedal feel, eliminates sponginess and delivers more consistent stopping performance under repeated use. Abrasion- and corrosion-resistant construction enhances braking efficiency and long-term reliability in spirited driving conditions.
