Seeking their first away win of the season, the Brumbies made the most of their rare visits into Stormers' territory with three tries then pulled off a massive 226 tackles to come out on top at DHL Newlands.
Captain Christian Lealiifano described the Brumbies' performance as "an incredible effort from our group".
"[The Stormers] just kept us under pressure the whole time and we couldn't really unlock our backline the way we wanted," Lealiifano said.
