If you have the sporting you already have the side skirts, spoiler etc, the Abarth had slightly more flared front and rear wheel arches, so i'm not 100% but I don't think they are a straight fit.
If you want to look at body mods then generally speaking german tuning websites are the place to start. you'll usually find some aftermarket Abarth body kit that will fit a standard Evo, splitters for under the nose and other mods.
To be honest the Evo was developed to take into account a lot of the styling cues that modifiers where using at the time. If you look for modified Evos you'll find many with improved looking wheels, some colour coding or removal of black trims to get everything looking smooth and flowing.
My sporting already has 17 inch wheels, factory tinted window, foglights hexagonal grills etc, it sort of already looks like a modified car.
