09 Design 09D BBK Replacement Brake Discs Pair 330×24 mm – Fiesta ST Mk8/8.5
Refresh the stopping power of your 09 Design big brake kit with this matched pair of 330×24 mm replacement discs. They are built for hard road use and track work, with strong bite, stable pedal feel and dependable heat control.
Each disc uses FC25 carbon steel for high thermal stability and strength under repeated heavy braking. The blackened finish helps resist corrosion and supports even heat distribution. A motorsport-inspired groove pattern clears gas and debris, keeps pads clean and reduces glazing, so braking stays consistent and fade is reduced.
These are floating replacement rings that mount to your existing 09 Design disc bells using the original bobbin hardware. The floating setup allows controlled expansion, which helps prevent warping and keeps the pedal feel consistent when hot. Sold as a precision-matched pair for even balance and wear.
Fitment is for 09 Design BBK FBR017AA on Fiesta ST Mk8 and Mk8.5. Please use the vehicle lookup on our site or check the Vehicle Fitment tab to confirm compatibility.
