MIA's Description

StopTech Big Brake Kits improve performance by increasing heat capacity with larger rotors and reducing system compliance with stiffer calipers and stainless steel lines. The C43 caliper is lighter than the ST40, uses a common DR21 pad shape (11% more volume than ST40 pads), and features 36mm/42mm piston bores for the Subaru BRZ/Scion FR-S. It allows for easy pad changes and comes with StopTech SR race pads. The 2-piece disc assembly provides float for thermal expansion.
