Can you unlock the Audi R8 in Midnight Club LA without the Social club?

My social club page is confused with itself, and Rockstar won't reply to my emails. However, do I need the Social Club to unlock the License rewards? The site sys 'in-game acheivements like the Audi R8', suggesting I don't have to download it, and that it will simply unlock when I complete the requirements. Is this true?|||no, in order to recieve the rewards you must sign up.. because when i first signed up i had already half of them completed and i did not recieve the rewards until i was signed up.. so my answer to you is to sign up and get your r8 in no time...
