Dodgers Star Hanley Ramirez -- My Lambo Spits FIRE!!!

L.A. Dodgers star Hanley Ramirez wanted a hot car ... so he got one that SHOOTS FIRE!!!!

TMZ Sports has learned ... Hanley dropped around $550k for a white 2014 Lamborghini Aventador -- but wanted to make it stand out ... so he went to The Auto Firm in Miami and upgraded the exhaust to one that spits flames.

We're told Hanley has already shipped the car back to Los Angeles -- so if you see a pimped out fire-breathing white Lambo on the 405 ... it's probably best not to tailgate.
