yeah i would think the stock fenders weigh less but...weight isnt the issue. one of my close friends has a car and it got wrecked in the front slightly and painted the front bumper fenders and headlight doors black and it seemd to look fairly good(the car is white) but i didnt even know they made these fenders till last night and i looked into it a little to see if they made anything and i cant seem to find a whole lot on the topic. trying to decide if its that or just with a CF hood.
