SPL brake cooling air deflectors deflect air passing under the car towards the front brake rotors for increased brake cooling. Fabricated from T6061 aluminum with a flat black powdercoat finish. Note: Installs with SPL PRO v2, SPL PRO v3 or SPL TITANIUM series tension rods only. These deflectors are not compatible with any other tension rods as they mount on specially machined holes on our tension rods. Designed for use with 17" or larger wheels, may require trimming for smaller wheels.
