ok so had an accident in the 1.8t the other day (some tit pulled out at the last moment from a junction) and suffered a bit of damage. I was thinking a while ago about fitting an s3 bumper, so I read up and saw that s3 arches are needed. as ive now had the crash, a bumper and arches are needed. so could I buy some s3 arches and a bumper and fit straight on? or do I need any other bits?
