I just purchased a brand new 2012 M37S storm front gray. Slapped on some limo tint and cleaned up the front bumper. My next couple projects is lowering with the Eibach pro kit and adding a rear spoiler lip. However, I'm torn between having the dealership install for $250 or an outside guy that I know do it for $90-$120 depending if its a stick on or bolt on. I'm sure theres hundreds of you out there that have put a spoiler lip similar to mine on. Can anyone give feedback on who you think I should go with? And if theres any pros or cons going either way. Your thoughts would be hugely appreciated. THanks
