Was at a Chevy dealer today the rear fenders are rolled from the factory on 08 hhr don't know about 07, But even with the factory rolled fenders the location were my tires rub will still need to be trimmed.

 

So, do you think the amount of rolling that I did will give me the clearance I need? How much of the rear fender do you think you'll have to trim for your 235's? How much of the fender would you be leaving? 1/2"? 1/4"?
