I would concur that 2600 pounds car and driver is the right number. I'm 260 pounds and my car and I meet the weight requirement.
Although would the additional 50 pounds make it easier for new guys coming into the division to not feel like they have to get the car as stripped to still make competitive weight?
Heck, if we make it 2650, I'm having a Double Whopper with Cheese for lunch instead of my Lean Cuisine....(j/k)
On the Windshield, I could care less about the weight aspect of the Lexan, I'M JUST TIRED OF CHANGING WINDSHIELDS.....brand new windshield after two races already has two small chips. I could have installed a Lexan (with little or no appreciable weight difference) for the price I'll have in yet another windshield for next year.
