Since noone else is posting pics, I will.
I wouldn't say my car is visually impressive, but I do consider my build to be somewhat "rally inspired". Outwardly, its what you might call "first steps" towards the "rally look", and since your car is pretty much stock, it could be a direction to start.
As others have mentioned, you can do a lot with a few simple things: Mudflaps, some wheels inspired by rally cars - either the 10-17 spokes used on contemporary R1-R5 Fiesta rally cars, or something a bit more old-school (6 spokes or even classic 90's OZ rally racing wheels). A mild choice of spoiler and a tasteful exhaust to round out the package
I'd say also important is to keep the car at or near stock ride height, and not lower it. This is harder than it sounds if you also want to modify the suspension, but to be honest there's nothing really wrong with the stock springs. Add some Bilstein B6 struts if your shocks are going. If you don't mind assembling parts instead of just buying an aftermarket spring set, I've got a neat stiffer option using 3.0" and 2.5'' coilover springs on the stock struts.

The other accessory that adds some rally feel...dirt! Half kidding.
