Ask a Question
  • What is the radius from the center of the disc to the outside of the caliper for this setup? The reason I ask is because most rally cars run 300mm disks and 15 inch rims. However, most rally cars are Subarus and not Mazdas, so I am having a difficult time finding performance brakes for my rally Mazda build, because most performance brakes are very large, and are designed for 17 or 18 inch rims. Thank you for your time.
