The information above is provided to confirm fitment according to the vehicle's wheel diameter. Depending on wheel selection on the vehicle, some vehicles may require a wheel spacer be used to provide optimal clearance between the wheel and caliper. Model specific brake kit templates are available at no charge to check for clearance before purchasing. Professional installation is required for YSR Big Brake Kits.
