I Should probably clarify as there are tons of people with the misconception that the z speed under shroud will mount up. It will not. the kbd bumper extends out a lot further and the z speed under shroud is meant to fit OEM. There will be a big exposure gap from the KBD bumper and the under shroud. I purchased this bumper, the z speed under shroud, AND the Nismo extension and it is getting installed tomorrow. Not sure why people recommend getting the under shroud as it does not support the bottom of KBD it is not long enough. But I bought under the impression it would and then had to rebuy the Nismo EXTENSION so it will. ALSO: the Nismo extension doesn't fit perfectly on the KBD the bolt holes wont line up with the bumper so best bet will be to ziptie the bumper with the bolt holes of the extension Alot of the bumper install videos really need to clarify this type of thing and actually show under the car once it is mounted... I have watched every single KBD bumper video on RU-vid and not 1 shows underneath the car. It really comes down to whether you want a big gap underneath where rocks can fly up or not. I wanted to do it properly so bought the under shroud, the Nismo Extension AND new fender liner to ensure I don't have a ton of gaps and things not lining up
@@johnayy Ive had my bumper on for like 2 months on without the metal support bracket, but I don't know where it goes exactly. If you can't find out where, it should be fine without it. It won't come off easily
