GKTech - Bolt on dual caliper brackets - Z33X-BRKT

The GKTECH Z33/Z34/G35/G37 dual caliper brackets feature CNC machined 6061-T6 aluminium and allow the use of either Brembo or non-Brembo calipers. This includes Akebono.

The brackets only space the hub out 8mm and do not require any modifications to fit and also allow the use of the drum e-brake.

We have also added the option of purchasing axle spacers to this kit as the plate spaces the hub out 8mm, this meaning the driveshaft is 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

The brackets are available on their own, however, if you want to avoid wasting time shopping around for all the individual parts, getting custom brake lines made up or running generic parts that may or may not work then we suggest having a look at our complete kit.

Vehicle Compatibility:
- Nissan Z33 350z
- Nissan Z34 370z
- Infiniti G35
- Infiniti G37

What calipers do I have to use?
Whichever calipers you have now, you need another set of the same calipers. Calipers can not be mixed between models. Ie. you can't run 1 Brembo caliper and 1 OEM Nissan caliper

Will this kit work with aftermarket knuckles?
These brackets are designed to be used with the OEM knuckles. They can NOT be used with aftermarket knuckles.

Will these work with any Wilwood calipers?
No sorry, the bracket has only been designed to be used with the OEM fitment calipers. 

Should I run an axle spacer and if so, what size??
By installing this bracket you are spacing the hub out 8mm, this is taken up by the driveshaft. This causing the bearings inside the driveshaft to run on the edge of the cup, which can lead to premature failures. We suggest adding axle spacers to put the stretched amount back into the driveshaft to ensure it runs further inside the cup and in turn is stronger and more reliable. We recommend checking which size you need by jacking your car up and dropping it down on ramps, this will load the suspension to its normal operating height. From there, disconnect the diff to driveshaft bolts and with the driveshaft in a relaxed position measure the gap. Keep in mind the distance of the plate that is supplied with this kit and factor that into the final number, that will tell you what size axle spacer you need. Simple answer for 99% of setups is 5mm if your car isn't super low / 10mm if your car is super low.
