Thats seriously low! How do people get their cars any lower then
it isn't that low really lol - the road outside my house is heavily cambered and the car literally sits either side of that camber so it looks like its super low
in reality i haven't had any problems at all - only thing i scrape is my mud flaps on the most awkward of speed humps; the squarer type usually
i posted the pic to highlight how you will have problems if you go lower than 30mm; especially if the roads where you live are like mine
