17" is the optimal wheel size for just about any car on the market. great response, light weight, and great handling. any bigger and you'll lose power, lose response, and lose unsprung weight response.
simply put, 17" is the best all-around. cheap tires, great response, and good looks. but to each his own. if you want more get more, if you want cheaper tires and good response then go with a 16". anything more than a 17 on this car and you'll lose response in turns/curves and you WILL lose power and braking. it's been proven on VW gti and gli, and on hondas. and anyone wanting to argue feel free,
