Only new easy way I've seen is a youtube video where they changed the rider's height to a lot shorter and he went significantly faster. That's an easy one to do that requires no hacking whatsoever.

I ride zwift in the same bike, wheels, weight, height, aero helmet that I use on race day so I can have good predictions of how fast I'd actually go at given watts. I don't ever do zwift races, so gaming it doesn't interest me whatsoever. I'm actually interested in the exact opposite.
