I'm also intrigued by that tab. Maybe for consecutive stages in different locations? Would be odd if we weren't be allowed to use different setups traveling from Wales to Spain though.
It's used when you do Rallycross and even landrush for some reason (though that's probably because Landrush is "None of the above"). And IIRC you can tune a setup and save it in the Dirtfish rally school if you joyride or if you use the academy.
The game features are awesome. I love the career mode, I love the online mode, I love RX and Rally (don't like land rush much), I love the stage generator etc. I just think the tyres have too much grip. I think this game is 95% perfect. It just needs a more realistic tyre grip level, and more interesting locations (Michigan and Spain are poor. Wales and Australia are awesome). Then it's as good as it can ever get.
I actually really like Spain and Michigan, and don't like wales *as much*, but that's probably because there were some really good Wales stages in Dirt Rally already and Dirt 4 captures the character quitwe well.
The Career mode is indeed great! I like how it doesn't force you to grind money in order to compete in the events you want, too. It's involving without getting in the way too much.
I'd also like to detail something I've said in another forum:
So I just "Finished" my first weekly event in Dirt 4 by... retiring. Oops. And it was all my fault!
When I embarked upon the event the game warned me that my vehicle may not be upgraded enough to make it to the end. In Dirt 4, you can upgrade your car but those upgrades do not affect performance: They affect durability. However, since I started the weekly event basically straight out from starting the game proper and I really wanted to bring my own car I only had a fourth-hand Opel Kadett available.
During the event I made quite a few mistakes, in no small part due to my unfamiliarity with both the course and the car. So the car got more and more battered, and my engineers were barely working within the time limit to get it all working again. In doing so I had to make a few choices on what to repair (quick fixes all the way) and what to keep. And off course, I neglected the clutch. In Dirt Rally, the clutch was never a problem. You could abuse that thing to hell and back, downshifting like a madman to get the car to stop faster. This was a mistake.
Had I replaced my clutch I would have finished the event, but instead at the start of the last stage my co driver noted that the clutch seemed like it developed an issue. As the event went on it became harder and harder to get the car to move forward as the clutch overheated. I ended my stage halfway down, at the end. The car had simply lost all the ability to get engine power to the wheels as the clutch had practically melted.
So that's a thing now! In Dirt Rally your car would be slower and handled worse when you battered it, but it would always be the *other* cars who ended up with blown gaskets, clutch slippages or a variety of mechanical failures. Not here! Here I was simply punished for my short-sightedness.
Hell, I could have skipped the upgrade process entirely and just asked to be a driver for another team, which would have netted me less money but would have given me a more durable car. But hey I was eager to try out the livery editor and ... yeah! Forgetting that Rally is ultimately an endurance sport.
So yes I'm enjoying Dirt 4 quite a lot. Much has been made about the physics of the cars already, but I mostly like what I've played thus far: In simulation mode (i've ignored gamer mode which I've been told is quite a lot like the previous Dirt games) the cars feel a lot heavier, and weight transfer is a lot more pronounced this time around. People have complained about the rear ends of the cars feeling
too planted on gravel, but I'm not really seeing that. I'm just having loads of fun with the career mode, which is a proper progression again rather then the same championship being made progressively more difficult (Dirt Rally) or a very fixed tree of things you have to do even when they bear no relation to eachother (Dirt 3).
