I've also now driven the ASR F1 car and the new DW12 version, since I have some leage races coming up with the latter.
The new DW12 is indeed now a couple of seconds per lap slower than the previous version, you can feel immediatly less mechanical grip and a bit less downforce through fast corners.
The way the car reacts is pretty much identical now, the new tires are also reacting exactly as the previous ones were.
With the reduction in mech grip you also have much less grip-feel through force feedback then before. Even after you adjust the setup for max. mech grip, glueing the car as much to the road as you can, you still need a fairly high caster to generate some front-turn in. Very similar now to the F1 car were you are 100% forced to do this.
I'm still not the biggest fan of this car, as I always feel like I'm not really in control as soon as I push a bit and also the curbs are usually death
Also in the case of longer races, there is exactly one strategy possible: Drive the alternate tires with exactly the fuel amount you need; refueling happens during the tirechange and is faster than the tirechange anyway and also the Primary tires (unless you are forced to use them by the rules) are useless.
The ASR car was actually good fun, even though you can immediatly tell that you will go crazy fast around the tracks (compared to the real f1 cars from this era) as soon as there is good rubber on the track.
It was interesting how similar it felt in almost every way to the Reiza Formula Classics, which is probably not a bad thing^^
I think the setup range in these cars will be very small though. Just a small range in aero-settings on both ends and a certain clear balance in suspension ect. will be driveable imo. Everything else will either be understeery as hell or dangerous as hell
Haven't looked at tirechoices and stuff and if there are any strategic options.
