You will need to change the width for the following:

.forumbit_post .foruminfo {
    min-width: 30%;    width: 57%;}
.forumbit_post .forumactionlinks {
    width: 5%;}
.forumbit_post .forumstats, .forumbit_post .forumstats_2 {
    margin-right: 2%;    width: 12%;}
.forumbit_post .forumrow .forumlastpost {
    width: 22%;}

Make sure the percentages still add up the same or you will have problems.
