The GKTECH Z33/V35/G35 dual caliper brackets feature CNC machined 6061-T6 aluminium and allow the use of either Brembo or non-Brembo calipers for use as a standalone hydraulic handbrake. They only space the hub out 8mm and do not require any modifications to fit and also allow the use of the drum handbrake. We have also added the option of purchasing axle spacers to this kit as the plate spaces the hub out 8mm, this meaning the axles are essentially being stretched that 8mm to compensate for the thickness of the plate. This can now be taken up with the use of an axle spacer. We have different sized options available as it is also a good opportunity to select a different size axle spacer if you were running a different diff/driveshafts combination or have a very low vehicle Vehicle Compatibility: - Nissan Z33 350z - Nissan V35/G35 Skyline/Infinity
