The force of the 8 lbs is directed down unless the car was flipped on its side. What you really want to look at is, the mass difference in the roof times the lateral acceleration of the car and the height of the mass you are changing if you want the real torque the roof provides on the car.

OK, so I honestly thought you were kidding. You'll have to excuse my ignorance on the subject, I know next to nothing about physics and the formula for determining a vehicle's torque...but are you honestly saying that you believe removing 8lbs from the roof of an M Coupe will generate any where near 32lb/ft of torque? That means this roof mod would have the same, if not greater, affect on torque production as the 4.10 I just installed...

...if that's the case, I'm ordering one today.
