[3] Individually, Mack 10, WC, and Ice Cube continued to work on solo projects between group albums.

As Westside Connection, they contributed several tracks to film soundtracks and compilations, including "Bangin'" (from West Coast Bad Boyz II), "Let It Reign" (from Thicker than Water), and "It's the Holidaze" (from Friday After Next).

On December 9, 2003, the group released their second album, Terrorist Threats, led by the single "Gangsta Nation", produced by Fredwreck and featuring Nate Dogg.

In 2008, HipHopDX reported that Ice Cube and WC were considering reviving the Westside Connection project, with The Game proposed as Mack 10's replacement.

[5] In a 2020 interview with VladTV, Mack 10 reflected that any reunion without his involvement would still require compensation, as he owns the trademark on the group's name.
