if you want to stick with the stock size, than the michelin PRIMACY LC would be a good option, as it's a much quieter tyre than the michelin mxv8 that i assume you currently have on your aurion. otherwise there are the sp sport from dunlop, which i hear is quite noisy, or there's a type from Goodyear which i can't remember its model name, and finally theres 1 or 2 types offered by yokohama(c-drive and s-drive i think) which offers great performance. all of these tyres are available in the same size as your current tyres. personally, i would go for either the michelins or yokohamas for there performance.
