How long / Where can I look at mods available for the 2013 model Fiesta?

I'm not thinking of doing much to it at the moment, but knowing what's available would be nice.

Also, Anyone had experience of upgrading the wheels from 15's to 17's?

it seems most alloys are made for 17 inchers, but I'm guessing I'd need spacers and need to change my suspension and get my speedo re-calibrated?

17" alloys from the Fiesta should fit fine, you don't need spacers or touch anything to do with the suspension.

Most people don't bother with speedo calibration, you can use a tyre size calculator to see how much you'd be out by.

Depends on what you want to do, performance or visual really. When mine comes I'm upgrading bulbs and putting wind deflectors asap, probably the evening I pick it up :-P

Mostly all visual to be honest, It's only a 1.25 no point trying to improve performance haha.

But would like mods that I can port over to another bigger engined fiesta in the future (I've got this car for a minimum of 3 years then can hand it back, trade it in or pay it off or take out 2 more years.
