    Did some testing. And decided that tire is fine, laptimes are good, car is on point, and it is quite managable over the limit, so I don't know whats the problem, am I driving it too well or what, I don't know. I'll just pretend that others can drive too.

    The only thing which I am thinking about to "improve" would be slightly more rear wheels cooling. Few degrees cooler rears will help quite a bit to provide a bit more confidence. In general I use teperatures to control the limit of a car, so I can't make the tires to be "green" all the time, otherwise it will be just way too fast, or I will have redesign whole tire again, which no one will like anyway just me, and I'll just waste lots of time, and make myself less happy by making something that I believe less.

    I went back and tried 0.777. Suddenly I can drive it very well again. I've since done a bit of detective work to figure out what happened, because it's literally night and day vs when I tried 0.777 last night.

    The issue I was having wasn't really due to the tires (though they are certainly less tolerant of big slip angles than in 0.5, which you've convinced me is likely the proper choice), but rather due to the rear wheels locking under braking. I have a Thrustmaster TSXW wheel, and on that system you have to recalibrate the brakes every time you reboot (or unplug the wheel).

    What was happening was that I hadn't done this (after yet another unwanted Windows update), leading to an excessively-sensitive brake pedal that caused the rears of the W125 to lock up suddenly under any sort of trail-braking. The effect was subtle because I was driving at night, with the sound down very low and therefore I didn't hear the rears locking at all! The result was that the car would step out the rear far too much on corner entry, and that was especially unforgiving on the new tires. But it was totally my fault, and with my brakes re-set, I quickly adapted my style to suit the new tires.

    Today, I found myself driving 0.777 just like 0.5 (in fact, I was a bit quicker - the tires seemed to have a bit more maximum grip), but without the lurid slip angles you were talking about. I agree that I have never seen an in-period video of anyone drifting one of these grand prix cars! As you said, the most I've seen is a quick "wiggle" on corner exit (along with big handfuls of steering correction to keep it all locked down).

    Bottom line: I stand corrected and I again appreciate your willingness to both engage and also dig into the source material to "get it right". Next time, I think I will check my equipment more thoroughly before I say anything. That having been said, I'm looking forward to trying the 0.79 update to see if it's a bit more forgiving of the occasional error ;)

    Thank you, I am all hoping people will love things i do as much as I love it, even though I know that my prefered "realism style" is a bit sharper, more challenging than it is usual.

    It is a bit strange that you had rear wheels locking, it shouldn't really happen, or at least be rather gentle. I don't even use heel and toe with this car, just downshifting. What tracks do you drive ?

    Your issue reminds me a period when I had some messed up setting in content manager which resulted in my steering and game steering degrees mismatching, and it took way too long for me to notice, I just though that I was very bad with new steering wheel :D So many online races I have lost then...

    0.79 should be more forgiving, but not forgiving in general. You should be able to abuse the tires a bit, but I wouldn't do that for lap after lap the whole time. By the way, full fuel tank should give the car more traction.

    I was testing using Donington 2018, and the spot that gave me the most trouble was corner #4 (The Old Hairpin). My usual technique here is to trail-brake a bit into the corner to keep my momentum up as I clip the apex. But my rears were locking up under the combination of trail-braking and lateral G's, so by the time I reached the apex, the car was far too sideways to recover with the steering lock available - leading to a spin.

    I love these cars because they really punish bad habits. After driving one, you can hop into almost anything else and find that you're quicker than before. In that respect, they are great training cars.

    Sorry to double-post, but you might not see it otherwise. On the 0.79 car, did max grip from the tires change at all?

    Or am I just more tempted to over-drive the car now that it's a bit more forgiving - resulting in slower lap times?

    Yes, I actually reduced the grip a bit, as I noticed tjhat I was driving with touch too low pressures, and it appeared like 1psi more of pressure gave more than a second of laptime (tested at Deutchlandring), and then it was too fast, so I had to reduce the grip slightly. It did a bit to make more predictable car, but of course speeds naturally drops a little.

    Not representative at all:

    the two @ Sergio Loro’s Roskilde where almost 2 seconds apart I favor to the Mercs.
    Would be great to see you, Mantas, and Gary try to somehow bop these beauties....

    cheers, and all the best!

    Loving the challenge of this thing. It will really teach you patience and throttle control.

    @Ace Pumpkin I hate those three letters "bop", I don't want to have anything with them. Especially in context of classic cars.

    I haven't done a lot of comparing, but in most tracks the cars should be rather close I guess, and probably in some Merc. should be faster, in some - A.U.. Your Rosklide test isn't the most representative.

    @Kondor999 Nice. Thats quite a big yaw angle right there, glad to know you survived :D
