Problem Cars

[dickita15]

Brakes and gearing also come into play for a lot of cars.

The problem with dropping weights is that a lot of these cars are kind of Porky anyways. I am not sure how you legally pull a couple hundred pounds out of a Saab 900, for example.

It is a "big" car to begin with.

Had a new kid this year who bought a 900 in B this year and had never scaled it. Lucked into a 3rd place and came across the scales at 150 pounds light.
But your point may still be valid.
