Individual wheel weight scales.

Ya no ****. That's why I said stock car. They change stuff all the time. The dirt trackers are always wadding stuff up.

You’d be surprised how many drag cars, or even street/strip cars have bent shocks, bound up suspension parts and other stuff that goes uncorrected because they don’t scale.

I always hoped the drag guys would scale more like the stock car guys, but they don’t. The can’t see the value in it. I forgot to mention springs that have gone soft. It’s usually the right rear spring that gets it first.

Stuff like that affects hook, RT and driveability. But it is largely ignored by the masses.
