All upgrades and lower it as far as possible then put on the best tires...That's...not something I'd call tuning, racing or otherwise.
I mean I guess the game is a game in the end so it's about having fun and that's all good and fine, but this..isn't really something worth showing off. Using suspension settings like they're an on-off switch kind of just shows you don't really understand how they work (though I'll admit, I used to do that with most of my cars way back when before I learned more about what all the settings actually do). At least you haven't maxed out your camber or toe settings. I'm going to guess you're not really using much in the way of braking techniques to initiate, because with your suspension slammed it's going to be really difficult to transfer weight effectively.
As for the photo, I actually gotta stick up for you a little. I personally think a zero counter drift with a big angle on the racing line is pretty much the perfect drift. It means you've initiated very precisely and have excellent throttle control. Now I can see that in this pic you're reducing counter to come out of the drift, rather than just holding zero counter all the way through, but I just wanted to let you know that zero-counter is definitely not a bad thing.
I can see you have an understanding of exiting and avoiding snap oversteer to some extent, my suggestion would be that you work on learning to drift proper. I think you'll have a lot of fun, you probably just need to get a better feel for weight transfer. I would suggest buying another RX7, leaving it totally stock except for maybe an LSD (try without for a while first so you can understand the benefit better) and oil change, putting comfort softs on it and working on Autumn Ring Mini. You're probably not as far off as you think, and your trouble may stem from trying to learn the basics on tuned cars and with other peoples setups. All the good drifters here learned on stock or very mildly tuned cars
