The man who claims Russell Brand nailed him last year with his car now says he suffered $185,000 in damages.
TMZ broke the story ... Victor Sneed sued Russell last year, alleging he was walking when he got mowed down.
Sneed just filed legal docs ... claiming he has more body part damage than Zsa Zsa -- specifically his left hand, left arm, left hip, neck and left wrist.
Sneed says he's already shelled out $45k in medical expenses, and he sneeds another $140k for future surgeries.
Brand says he's not to blame for the accident.
