Will a car that's been lowered fit through the car wash?

not sure you have to ask them that one

they have a plank that works for lowered cars

System runs on a guide rail.

it depends on how long you're talkin the wheel well as to where your wheels go in and are pushed through the carwash are usually about 6 to 10 inso your vehicle will at least have to clear that sell it can be pushed through the wash
