DIY: Flush Mount your "H" Horn Button (MOMO) (91-05)

3 May 2020
Learn how to take a OEM JDM NSX-R MOMO horn button or any MOMO button with a "rounded lip" and convert it to a "flat lip" or flush mount style for a cleaner look. This was done for a MOMO hub mount, but the concept is the important part and is the same for a Works Bell or NRG style hub and quick release (detailed at the end of the video).

My original DIY for this can be found on S2ki.com: https://www.s2ki.com/forums/s2000-modifications-parts-193/nsx-horn-button-flush-mount-mod-1204856/
