Here's what I would like to see made available in a future patch.

Being able to group up to 4 racers to one online name [CLAN]

A modification/option of the friends online to be able to be switched/read to CLANS online,also showing what race mode said clan wishes to race in.

Being able to have one person in each clan designated as head of clan,this would show up with some sort of icon so the head of another clan could message pre race.

Being able to challenge another clan via nudge in each race mode.

Online rankings of each individual within a clan added up to show strength of clan.
