FAQ’S
Will these work with Skyline rear rotors (or others)?No, this kit is designed to be used with the S-chassis 9mm thick rear rotors. However we dp make a dual 2 pot Nissan (Skyline/Z32) specific caliper kit also. Please refer to our other listings
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, which is also why we have axle spacers included.
Is there anything else needed for installation?Besides brake fluid, everything is included in the kit. BYO tools.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.How do I know which size master cylinder to choose?Typically the 5/8 master cylinder is proven on an S/R/Z chassis running the single or two pot brakes, the lever feel with this master is balanced, having a longer more typical throw to gauge feel while still efficiently locking the rear brakes. The 3/4 master cylinder is larger, so when used in the same setup the lever feel will be more direct, firmer, and require less throw to lock the rear brakes.
