i personally just get wheels that fit correctly, but ive seen locals use a wooden bat and a heat gun to roll their stanced cars perfectly.
they just heated the fender and tapped at the metal to roll it inward first, then tap some more to push out just a hair if they needed a tad more clearance. the trickiest part appeared how well the push outward would flow with the arch on the front bumper...without breaking the tabs. if they ooops... zipties...
