This lora for Flux will mod any car in the "Rauh-Welt" famous japanese tuner style.

You can make porsches with it of course, but you can also make any car use that style.

Just use "rauh-welt" in the prompt, you can also add stuff like "with a widebody kit, wide fenders" and "sticker on top of the windshield with writing "RAUH-WELT" " if needed.
