09 Design Front Brake Kit – 4-Pot 330x24mm (909) for Ford Fiesta ST Mk8/8.5
Upgrade your Fiesta ST Mk8/8.5 with confident, consistent stopping power. This 09 Design 909 kit pairs lightweight 4-piston T-6066 forged monobloc calipers with fully-floating, grooved 330x24mm FH25 cast carbon steel discs. The result is strong bite, better pedal control, and improved heat management on fast road and track.
Forged monobloc calipers are stiff and light, which helps pedal feel and reduces flex under hard braking. The fully-floating disc design allows the disc ring to expand with heat, helping prevent judder and keeping braking consistent. Grooves help clean the pad face and maintain performance in repeated high-temperature stops.
Engineered specifically for the Mk8/8.5 Fiesta ST, this kit balances performance with wheel clearance and everyday drivability. It offers a clear, progressive pedal that is easy to modulate, with reduced fade during spirited driving.
Wheel clearance: Fits under 09 Design Assetto Gara wheels without spacers. OE wheels require a minimum 10mm spacer.
