They were made with a 0.2mm nozzle in mind, what I recommend is what. This person did, they left supports attached to the bottom of the buggy and the railgun and just painted em black to look the part.
Did you print the version of the buggy that comes disassembled? That one was designed for fdm and barely has any supports needed ^^
Sadly I can't really give you any specific settings but I'd recommend you make the supports as thin as possible
