NASCAR Racing: Drivers weight, cockpit area, race nascar

Question
During a segment of speed week (on the speed channel) Jimmy Spencer alluded to what he called the "Gordon Rule".
In that since he only weighted 135 lbs and the other drivers weight was a lot more, that his car had an unfair advantage.  He went to state that NASCAR had implemented the "200 lbs rule".  Was that just complete fabrication, or was there some truth to the statement?-------------------------------------------

-----Question-----
Does each drivers weight count for the overall weight of the car?
-----Answer-----
During the inspection process, either before and after qualifying or before or after the race, things like height, parts, and weight are inspected.  In these instances, it is the raw weight of the car only that matters.  So Tony Stewart (know for being "overweight") will not be disqualified for being fat.  The only time it matters is at the race shop where the crew sets up the cockpit of the car so it is suitable and comfortable for the length of the race.

Answer
Nascar is really focusing on each car being the same as far as the tangibles, height, weight, angles, etc.  If a car's driver weighs less, the car will not stay "glued" to the track, and the handling will most likely be better since there is not allot of weight pushing on the chassis and tires. Anyway NASCAR sees the advantages, they might have a rule to where the crew has to have a minimum of 200 lbs in the cockpit area.  They might do this by adding weight in certain areas.  Once again, drivers over 200 lbs do not have to worry.
