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 10mm however our brackets only push the hub out 6mm.
Is there anything else needed for installation?
Besides brake fluid, everything is included in the kit. BYO tools.
