These specially designed brackets are designed to mount a Brembo e-brake caliper on the back of an NSX. This kit includes right and left brackets, caliper hardware (not shown in images), spacers and attaching hardware. The brackets attach to the oem brake shield location (that must be removed to install). As shown in the images.
While this kit is designed to bolt directly to the car and accommodate a 350mm diameter brake rotor, the offset spacing will have to be tailored to your specific brake rotor set up. This does vary from brand to brand and will require you to change the overall spacing of the attaching hardware. Kit comes with 6 x 1.0" spacers.
This is only the brackets and hardware. Not the calipers. You will need to source the caliper separately.
