You made the same statement on the wiki pages for Burnout 3 as well, but I tested it myself and Skipdraw 3 does remove the vertical bars.
(And the bars only show up in 480p Progressive Mode in the first place, so they can be completely avoided if necessary by just not booting into Progressive Mode).
