I was contemplating should I open a new topic or not but didn't want to necro 6 year old threads either lol. Basically I need the "bust a friend and race a friend" trophies to get to Platinum. If you do, Id appreciate it.
I don't have it anymore, however I'd suggest going to psnprofiles.com and set up a boosting game session and I'm sure you'll find some other players going for those trophies.
