Will these work with Skyline rear rotors (or others)?
No, this kit is designed to be used with the S-chassis 0.35" (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 0.39" (10mm) however our brackets only push the hub out 0.19" (5mm), which is also why we have axle spacers included.
Is there anything else needed for installation?
No, everything is included in the kit. BYO tools.
