I had 17" sparcos last winter and 3 wheels bent. The worst dent I hit a huge pot hole which busted one of my gmax tires soft ass sidewall. The others just got bend driving on shitty nyc streets and that was with 45 series tires. Damn shame cause I loved the way they looked and how much unsprung weight it gave the car. So my lesson is no more 17" Gravity cast made in china wheels for me.
