When I first saw someone tap a post and use the tiny 2-56 screws to put a car back together, it blew my mind. I had just never thought about the possibility because it wasn't a problem I was looking to solve. Plus, I figured it required special tools. Little did I know it's easy to just drill-and-screw without even tapping.
But in all honestly, I never really unscrewed a car once I put it back together. It looked nice and I felt more "pro" doing it, but I don't think I ever took advantage of the easy access it offered...but I was also a very lazy modder.
So for the more serious racers...do you even unscrew your mods during the test & building of your cars?
That also had me wondering if anyone uses the unscrew-ability to strip their mods of resources after they race? Seems like an easy way to get extra use out of weights, wheels, and all the other guts.
