What would be the best size alloys to put on my 306, i am thinking 16" would be best but is it possible to fit 17" ? I am looking at buying a set of PEUGEOT 206 GTi 180 17" alloys for my 306, will they fit without messing about with the aches and will i need spacers? Also can anyone recommend the cheapest place to get alloys online? Cheers Jebile
