*Required combo item


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. 

The GKTECH S-chassis dual calliper hydraulic handbrake setup is the only COMPLETE kit available anywhere. Literally, everything required is included and it's a range of GKTECH and Wilwood components. If you have an S-chassis and you want your rear brakes to lock up in an instant, this kit is the way to go. 

Now includes our new CNC machined aluminium handle. Available in silver, black, blue or pink. 

We have also added the option of purchasing axle spacers to this kit as the plate spaces the hub out 6mm, this meaning the driveshaft is essentially being stretched that 6mm 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.

We are also now taking orders WITHOUT the Wilwood components. If you live overseas this may be a cheaper option for you. This also means that we can continue to sell these without having to stock large volumes of the Wilwood items or sell on pre buy. Simply de-select the Wilwood components at the time of adding the kit to the cart.

Vehicle Compatibility:
- Nissan 180sx
- Nissan S13 Silvia
- Nissan S14 200SX
- Nissan S15 200SX
- Nissan A31 Cefiro

NOTE: If you are running standard hubs/knuckles the 5mm axle spacer is required
NOTE#2: Will NOT fit European delivered S-chassis' without the use of JDM or USDM calipers/rotors.
NOTE#3: Designed to be used with standard S-chassis 9mm rear rotors
NOTE#4: The wilwood calipers have a mounting hole of 3/8inch (9.52mm) and the studs used on our brackets are 10mm and as such the 2 mounting holes needs to be drilled out on the calipers to 10mm. This is very much a DIY kit and is easy to do.
NOTE#5: The brackets themselves will NOT fit the Gktech rear drop knuckle
NOTE#6: For the axle spacers, we can only confirm fitment on OEM wheel bearings


How do I know what size axle spacer to choose?
This kit comes with a bracket that is needed to mount the dual caliper bracket, this bracket goes between the hub and the knuckle.

By installing this bracket you are spacing the hub out 6mm, 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.
