Most of our big brake kits for the rear do not support compatibility with OEM handbrakes. 
But at times. there are some kits that work. Generally, we put a note on the product listing fitment section that says "WILL WORK with OEM handbrake".

Alternatively, we do have our Dualcomp big brake kit series (All-in-one Dual Caliper solution designed for Drift & Rally Racing​) that comes with a polished titanium handbrake though.

Here's more information about that: https://ksportusa.com/big-brake-kits/dualcomp-big-brake-kit/
