How car weight works

[dragracerray]

that did not show up right on the post
first weight is "car plus driver weight",
second "weight is rounded up to the nearest 5 pounds" this is race weight
third column is the "weight of the car without a 250lb driver"
sorry Ray

You always round down for weight. Example: 3164 is 3160

I’ll look again but in the example that NHRA gave with the Mustang I didn’t see anything about roundup weight even if it’s only 5 pounds. I won’t be that close, I’m figuring 20 over just to be safe.

When you fill out your tech card you need to know the exact minimum weight or you can get disqualified. That's the reason for getting it correct.
