324mm Rotor Caliper Adapters (R32 GTR)

Please note: Our adaptors now have stainless steel Heli-coils. The OEM Hex Head Bolts are now entering through the Heli-Coils on the opposite side. Please use images as a guide for positioning the adaptor only.

To begin, determine the left and right-hand side adapters.
They are marked as follows: HFMGTR32/RH or HFMGTR32/LH

2. Remove the Rotor and Caliper.

3. Grind or linish a small portion of the ground area of the knuckle until the bottom bolt hole of the adapter lines up. Place the adapter over the bolt hole and push through the Hex Head Bolt to ensure correct alignment.

4. For the Rotor to fit correctly, you may need to remove or modify the backing plate. This step is personal preference and can be done as appropriate to you. 

5. Position the Caliper Adapter on the inside of the knuckle, as shown in the images below and install using the 2x OEM Hex Head Bolts first. Then Torque to 60-70ft-lb or 81-95Nm.


6. Return the Rotor to the hub.

7. Refit the Caliper to the adapter using the 2x supplied M12 Hex Head Bolts. Then Torque the bolts to 60-70ft-lb or 81-95Nm.

8. Repeat this procedure for both sides, and you’re done!
