You've got something else going on.
There's no difference in the chassis or suspension between a base and a sport model. You can swap either set of wheels on both models - the base wheels on sport model have very tight caliper clearance in the front but they do clear. Sport rims easily fit on a base model - I've seen several base vehicles with no suspension mods running 265/305 tires on the sport rims.
