Well, I'm not familiar with the cinq nor the punto. But GT often means more fun, and more fun needs more brake power. So I guess they are double ventilated discs. The cinq has propably not due to smaller engine. So what you need, is the brake disc AND the caliper. But the conversion method I don't know. Be aware that you can't use your wheels anymore because of the offset. They'll come out of the arches and explode at first speedbump. So you need new alloys as well.
