@JustDrift893: This is a good drifting video. You're a bit conservative about clipping the corners, although that is probably just regulated competition training taking over.
This comes from someone who doesn't drift with rules anymore, but here are some comments for the Z34 video, take them with a grain of salt.
1:13 - Get Closer!
1:49 to 1:56 - Good.
2:09 - Disappointed, you can drift that corner much closer without hitting the wall.
2:52 - Still closer yet
3:00 - If you ignore the right-side stone, transition early, and clip that sharp edge early while in the dark, you can pull out of that corner through the barred zone with much more room to either speed up or increase your angle. It will be faster, as well, due to a better line.
3:45 - Ride one tire on the zone. I'm not sure if you're under "no tires past bumps" rules, but if this is an informal tandem as I assume it is, there are quite a few tricks you can pull through this section. 1. You can use that rail to affect your weight distribution, provided you are getting close enough, and give yourself more rear grip. You see the Lotus doing just that, although not very well, on the next corner. 2. Inside the tunnel, if you're very ambitious, you can ride both front wheels on the raised portion during the apex, as well as giving a later apex and coming out of the next corner (which leads into the long straight) with more speed. Of course, if you don't do it right, it will severely mess up your line.
4:09 The opposite can be done here, you can go wider, riding the dirt, and apex late for a better line.
Grand Valley is absolutely full of places like that, where being a little more reckless can result in a much more stylish, and/or fast, drift, especially in ways that are not necessarily accepted in the competition scene...
