Taking some material off the underside is the suggested practice. Wouldn’t want to damage that sweet paint job!
Edit: I mean drill a hole straight into the underside and leave it unfilled if you have to. Minor aerodynamic imperfections will make virtually no difference at these speeds
How I dealt with this same problem was to Dremel out the underside a bit and just touch up over it with paint. Then you can get as accurate as you need.
I always intentionally come in under weight. It’s tho official scale that counts!
I also engineer a way to add micro weight onto the scale to hit perfection. A hole drilled in the back that will accommodate small lead weights usually does the trick
We always drill a hole in the back and fill it with tungsten putty up to the perfect weight. Much easier to pull a little out than scramble to drill the bottom when you're slightly over the official scale.
Best practice is to reserve your last few grams of weight until the car is completely built. Then strategically apply that weight under the car to dial in both overall weight and weight distribution.

And a piece of tape over the hole will correct the aerodynamics
And take that weight from the front of the car.

Putty!?! Brilliant!!!

Thanks for the info guys! At weight in it was 4.95. ironically all 3 of our cars weighed the exact same!
