The GKTECH S-chassis dual caliper bracket allows the use of a Wilwood 120-10188 caliper in conjunction with an OEM S chassis rotor/caliper combo for use as a standalone hydraulic handbrake. It is super simple to install with the only modification being to the standard dust cover. 

Alternatively, 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 and check out our complete kit.

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

NOTE: Compatible only with standard S-chassis rear rotors in conjunction with a Wilwood 120-10188 caliper (sold separately). 
NOTE#2: Designed to be used with USDM or JDM S-chassis 9mm rear rotors and will NOT work with Skyline/Z32 rotors and will NOT fit with European S-chassis' calipers/rotors 
NOTE#3: 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#4: The brackets themselves will NOT fit the Gktech rear drop knuckle


I've heard dual caliper brackets push your hub out?Yes, some can as much as 12mm however our brackets only push the hub out 6mm. 

What modifications are required?Fitting an extra caliper in this space is not easy but this bracket does make things a lot easier and is an easy install. Simply trim your brake dust cover to suit. No other modifications are rqeuired. 

Can I use a Wilwood caliper with a Skyline/Z32 rear rotor?No. Wilwood don't make a caliper with the correct thickness to suit a Skyline or Z32 rear rotor and as such, we don't have something to suit. This setup will ONLY work with S-chassis 9mm rear rotors in conjunction with an OEM rear caliper. Do you sell the calipers to suit this bracket?We only sell these calipers in our complete kit and do not sell them on their own. Should I run an axle spacer and if so, what size??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. Simple answer for 99% of setups is 5mm if your car isn't super low / 10mm if your car is super low.
