If you just buy either the standard ones or the urethane ones for Lancer they will fit the sportback as the hardware location in the wheel wells should be the same. I am on my 2nd set of the urethane ones. When I ordered my original set I ordered the Evo X ones only to find out their screw locations are different and had to drill new mounting holes in the mudflap to use my stock screw locations. After my car got run into in a parking lot one cruise night this past summer I ordered the Lancer ones which fit perfectly. Hope this helps.
