Gonna give my 2 cents on this since I race, and I drift, and I personally have a good touch on car handling.
You're modulating the throttle and brake for your 0.6R run more actively than your 0.6N run. You're carrying more speed in your 0.6N run because of your confidence that the steering is "how it should be".
In the 0.6R run you are more cautious, hence the less angle control, (not that you carried more than 20 degrees anyway..)
Using Cold tires also means you naturally have to fight the car more to maintain a constant velocity as the grip-tarmac-slide threshold is slimmer than it is when you've preheated (golden line is harder to find). During a preheat run you will be able to slide out easier and hold it at an angle without juttering the wheel. This explains your throttle-brake modulation.
It's all probably a placebo effect, when you think "oh god, this changed so this is worse than what it was before".
Nothing has changed with the cars and their physics, as Scawen has highlighted. It's probably either, like I said, placebo, or your've tried the new extended lock, felt weird, returned to 36 and felt weird again.
Apart from BL track becoming bumpier and having a better racing feel, nothing has changed with how the car handles in drifting. Use 36 degree lock if you cannot feel the slide in the 45 lock.
I hope this has clarified the issue, as it's gotten cancerous to this point.
On behalf of all the faceplamed foreheads, I'm out.
Cheers
