Was looking at the Rear Nismo Fascia kit on Z1:

'Installation Note:
The NISMO Rear Fascia will bolt directly to the Non-NISMO 370Z. However the lower fascia retainer bracket will have to be removed. There will also be a gap in the fender liners. In order to properly secure the fascia and to fill the gap in the inner fender liners created by the NISMO rear fascia, you may purchase an optional hardware kit that includes everything necessary.'
is the optional hardware kit required or recommended for installation and will it look differently if I didn't use it?
