This is a complete kit, everything that is needed. Rotor size is 323mm. You use your existing Fiesta ST calipers. This kit does not require you to remove or bleed your brake system.
The supplied rotors are Premium grade (not economy grade). They have been drilled to fit 4x108.
If you want to supply rotors to Gold Coast for drilling, the total price will be $400 + shipping. That is a savings of $100 by deleting the rotors and $50 additional charge for drilling your supplied rotors.
