I gotta tell you, the internet is a marvelous thing. I'm mathmatically (among other things) challenged, and I was trying to come up with a formula to give you weight percentages on my roadster (front to rear, etc.). I realize now it is a simple formula. But when you don't yet have that formula... well. So I go online and ask Google to find the formula for me, and boom we're good. But better yet was a go-kart website (yes, go-kart) I found that literelly did it for you. It asks you (input) Total kart weight. I put in 3500 pounds (world's heaviest go-kart), as that is what I think total weight of my car should be after adding weight. It then asks % front, which I input 45%. It then asks % left, which I put in 52%, and then it asks % cross, and I input 51%. Press Enter and Bless you Baby Jesus, it not only shows weight of each corner, but also percentage of each corner. In my case 806.4 on left front (23.04%), 768.6 on right front (21.96%), 1016.4 on left rear (29.04%), and 908.6 on right rear (25.96%). What all these numbers mean and how they will balance the car, I don't have a frick'in clue! But it does give me something to think about at 3 o'clock in the morning between pee's.
