so i am trying to save money for a car/pickup so im trying to not spend any money on my merv until then. i just broke my spoiler today and i had some plastic laying around so ive started cutting it up and am making a spoiler out of it.

what do u think i should add to it? im adding the back lip so it wears down less doing wheelies . sides? another layer at the rear? what about something around the screws to prevent tearing them up when its sliding upside down on cement? any ideas?
