You'll need to get a hub that fits a HICAS model car. There's an extra sensor behind the steering wheel that reports the angle to the HICAS controller. Aftermarket hubs need to interact with that.

There are hubs out there designed for HICAS, just gotta look. I didn't see anything from NRG that stated it worked with HICAS, so you might need to contact the company to find a SKU number that will work.
If you decide to disable HICAS, you'll have to pull the steering angle sensor to fit your aftermarket hub, and then I really recommend either swapping the entire rear subframe to eliminate the HICAS steering rack, or to get HICAS eliminator toe rods for the rear.
