Has anyone just taken the washers off their trucks (the ones on the bushings) for a bit more wiggle? Or is this a ridiculous idea?
Yes, it is something I often do for really light weight kids when they are trying to turn but just can't quite get there, usually the bottom only, but sometimes top too, if they are really, really light / small and just can't get the bushings to do what they want.
That is the cheapest and easiest thing to try if anyone feels like their trucks are not turning enough, easy to try with no problem putting the bushing washers back in when needed.
Some other guys I know run no washers on all their setups, stupid loose is maybe the best way I can explain it, but they like it and it works for them, so whatever floats your boat there.
That is a lot easier than sanding down / grinding down / cutting down the bushings just to make them looser - done that a few times and took too much off, or messed up the bushings, but I didn't mind with the ones I had - a good learning experience.
* To add, using the Bones or other flat washer, as some do on here, is a very good in between as well, which doesn't cup the bushing and keep it squeezed into a certain shape, more often just the top, but you could use it on any, top or bottom, as well.
Some washers from hardware stores are rubbish and bend far too easily, but others work well.
