everyone is always talking about how anything/everything messes up the geometry... but does it really? has anyone actually mapped out the "geometry" of each truck? has anyone confirmed the stock/standard geometry of a truck is actually the "best" geometry?
There is no such thing as "best" when it comes to geometry, because the criteria is not objective, there is only "better for".
Certain geometries cause less wheel bite, turn quicker, are better for stability, etc... so one must find the geo that is "better for" what they are needing/lacking. Sometimes what people lack is mental, but sometimes their gear really is jacked up too (I saw a kid with two different model Tensors, a hi and a lo, with two different widths and random bushings that didn't fit his trucks - but he was better than half the people at the park. 99% of skateboarding is mental, but then again, this is the GEAR subsection, we aren't here to talk about the mental part).
