Be a "known" driver from one of the licensed series in R3E or similar and contact Sector 3 personally.
AFAIK All the vip drivers in R3E are actual professional drivers IRL, running in Adac/dtm /tt cup / etc...
What series are you racing? I don't know who every Vip driver in R3E is, or if it's only drivers from DTM, WTCC, ADAC GTM and Audi TT Cup.. But I guess you could ask @J-F Chardon to see what's needed to be one.
Hello @Matheus Biriba RaceRoom have written some explanations about it here: http://www.raceroom.com/en/community/#vip_driver_profile They pretty much ask you to contact them. http://www.raceroom.com/en/support/#contact I would try the sales email.
A little off topic, but hopefully not too far, I'm curious if there is a similar VIP badge/ribbon for the forum as there is for developers. If not it might be an interesting thought?
