I'm going to fit a splitter probably an M Performance variety to my car. I wont be going to the expence of buying a OEM version because I've got a feeling these things have the life expectancy of a WW1 fighter pilot! The question I have is that the OEM vwrsion seems to come with a support panel that strengthens the bottom of the bumper where as the cheaper versions dont have this. Is it that necessary? Are the cheap versions a viable option? Any advice you could give me would be most appreciated Guys.
