been looking about for a while for an s3 bumper and i have managed to find one. Ive looked through various posts on here but found no propper answers to if they fit or not. i am aware that s3's have wider rear arches but will the s3 bumper line upto my rear arches ok with out any modifications??? I dont know the year of the bumper as someone brought it for a project and doesnt know the year of it either but i dont know if they are any diff on the non facelift or facelift models?? will i need to buy any new guide rails for the bumper to line up ok??? any help will be much appreciated.
