I'm not say the guys in front are cheating as a rule, they just push the limits of the car, the driver and the rules. Compliance is about tech inspection, templates and measurements. Look a when there is a weight and plate change, particularly on the high dollar cars. They built those cars into the grey area, for example using cage designs and tubing to find the right balance for a particular car ith a particular driver. That takes time, money and skill. And it's right into the grey area of ballasting. Look at well known head builder that got a car bounced from the Runoffs. He was pushing the edge, reached too far and went over. The guys in front don't try to get that last tenth, they they to get that last one hundredth.
