Sorry... don't know why I read it as rear when you didn't put either.
FRONT bumpers appear to be the same for 5 door and MW models. There's a seperate part number for the 115bhp version of the JTD but I think it's only because of the open grille in the bottom left side of it for the turbo inter-cooler air inlet.
sorry can someone put a photo of an abarth bumper? i have the 5 door stilo and i dont know if there is a difference between the abarth 5d bumper and the 5d stilos bumper....
I don't believe the bumpers are different as the wings on the abarth and mw and front panel is the same also which fundamentally are what the front bumper is secured to.
