Motor upgrades for flux? Also question on wheel wideners

[Slowkrawl]

Hey guys, I am not really up to date or informed on the "big" brushless motors. I am tossing around the idea of a motor swap in the flux, mainly because it's bothering me that it's stock haha. The performance is awesome, but it's still stock! Is there a motor I could swap in? I don't want "bang for the buck" I want the best of the best, I basically just want to know what is out there? If anyone "in the know" could give me some insight that would be great.

Also, I was thinking about a set of wheel wideners but I have heard they just break more parts?

extended chassis is on the way, so I figure I might as well give it some lovin' while it's apart and cold outside. Thanks,
