hi, and i would personally loose the rear spoiler,but saying that its your car and you can do what you think,
As this is the kind of work that keeps me earning money[body-kits,rear spoilers,colour coding,painting alloys ect],so at the end of day its your car and your choice.
i just don't know how you get over all the speed bumps that's being put everywhere at the moment,as all the young ones up here are regularly back getting there splitters/rear bumpers repaired as too low?.
cheers and have a good day/night.
