Looking to buy some Sporting rims to replace the dreary 15 inch alloys on my 2007 1.4 active sport. Is there anything that i need to know before i replace the rim e.g speedo being off? extra wheel nuts needed? maybe if they will even fit the car? (please forgive me i am a complete and utter noob when it comes to modifying cars)

Speedo will be oit by 1-2mph but they are a straight fit on I did it to my brothers last week

As Paterson1 said just direct fit I've currently got mjet ones on mine from the nasty 15" steels which came with it and it's only 2mph if that out
