HFM.Parts Caliper Adapters have been finely crafted from T6-6061 hard anodized billet aluminium and are fitted with quality stainless steel Heli-Coils to maintain strength. Fitting these adapters with your OEM R34 GTT caliper will enable you to increase your original rotor size of 310mm to our 324mm GTR rotors, not only is this more aesthetically pleasing but it will help improve heat disbursement and brake performance.
*Suited only to R34 GTT’s with 310mm rotors and M14 caliper bolt holes as standard.
