Yes, they do gram count. They're trying to get every advantage they can. It doesn't mean that the weight difference constitutes a significant enough advantage to institute a rule change. If the other teams really wanted to, they could have hired lighter drivers if they thought it was significant. Then we would have a bunch of horse jockeys driving cars.

In some of the qualifying, the difference in weight between Her and say a Robbie G was the difference between first and 20th. That's why all those guys said forget it and the sport almost died. That rule change is huge and will bring back some of the bigger drivers.

You can't say definitively that it was solely because of weight. Of all other variables:
Chassis setup Driver Skill Engine Tuning Aerodynamic Package Weight You really think weight made the difference in qualifying?

75 pounds + to a car that light changes the qualifying run enough. You can figure that the car is probably 5% heavier with that weight difference. Lets just say that equates to 1% time difference, which I was under the impression its more than that. With the qulaifying being decided by hundreds of a second, that change in weight is huge.

It's simple phsycis really. Newton figured it out for us in Newton's second law of motion. (I think that's correct, been over 20 years) It's very easy to see the effects weight has on acceleration at any drag strip. It was huge when I was racing a drag boat. It didn't go faster when I took out the weight (well under 50 pounds). But it sure went quicker. And that was only a 1,320 feet race. Just think, over 500 miles what it would be like. |

A drag strip is different. Since you say it's simple physics right, then you are aware than aerodynamic drag is proportional to the square of velocity, right? So if you screw up your aero package your penalty gets worse as you go faster. If you choose the wrong tires, you won't have traction to deliver power to the ground. If your chassis isn't setup properly, you won't get all of the available traction.
My point is that compared to all other factors that could play into qualifying, weight is probably a minor one. If all other factors were exactly equal, than weight might make the difference, but other factors are never exactly equal. Quote:

It doesn't seem like 50 lbs would make much of a difference, but it truly does. This is not the Bonneville Salt Flats where you're running flat-out triple digit speeds...obviously, aerodynamics are the governing factor here. But aerodynamics plays LESS of a role when you're constantly braking and then accelerating out of turns from "street legal" speeds. In road racing, it's about power to weight ratio, just as much as it is aerodynamics. Do you think they make up all the silly weight rules for fun? Having a 50+ lb advantage is HUGE over time. It gives you an edge coming out of corners, tires wear more slowly, it's easier on the brakes...it really does add up. Not to mention, depending on where the weight is distributed, 50 lbs is MORE than enough to actually feel going around corners. I could feel the difference with just a 20 lb donut spare in the back of the 944.

O Roddie, those cars drag race off every turn. At Indy that's 4 mini drag races per lap. Cars with a bad aero package or bad anything else don't even make it in the show. Those teams are moot.
I don't really follow Indy cars so much so I am here or there on any rule change. But given all is equal other then weight, the lighter car will get to speed quicker. 4 times per lap @ Indy, it wouldn't take much of an advantage to add up. I wish I could post some photos of these wacky bolts I just made for a race team. They would spank me if I did. Lets say they put a lot of time into a lighter fastener that the avg Joe would think was a waste. |

Recently I went to a karting track with some friends. I was the tallest and heaviest driver, yet i was passing EVERYONE! LOL....they all said, damn, for a big guy I was sure fast! Of course I was just as fast as everyone else on the straights, but I passed then in the corners, since I knew how to carry my speed thru the corner and push the kart to it limits more than they did. Paul Tracy used to be about the biggest guy in ChampCar, and back about 6 years ago he would be the fastest guy and win a bunch of races, and the weight of the driver wasn't taken into account of the car weight. |

I mean a lot of factors come into play not just weight I'm hoping that she does well at the Grand Prix even on the site you could enter to win a chance to meet her which i think would be great |
