I think he's just talking DE - racing in the rain is another level. Just the start is crazy as anything behind row 2 and you won't even see the green flag, and from that point on visibility behind a car you are trying to overtake and finding grip to overtake is very challenging. Then, late in the race you are more likely to encounter lapped traffic who are very conservative and quite often they try to do you a "favor" by getting off the dry line and putting their car right where you want to be! And most rain races seem to have varying conditions, such as very wet and drying or mostly dry and then wet.

To race in the rain you really have to know the track and be willing to just let the car skate with the confidence that it will grip up before you leave the track. You also have to experiment every single lap with the grip to make sure you are not leaving any pace on the table due to improving conditions, while not going off or crashing if conditions are deteriorating. It's an odd mix of aggression and yet being conservative enough to be sure you finish. Hugely satisfying, as horsepower is MUCH less important in the wet and in a mixed-class race group and very wet conditions it is very possible to win overall in a "slow" car.

There should be zero need for you to reduce your pace without the TC/SC activated - assuming you are already driving smoothly so that you do not activate it.

IMHO the best way to learn to drive is by turning off all these aids and feel the full weight of the consequences. Then learn how to modify your technique to eliminate them. It may be frustrating at first, but you'll progress much faster and develop more feel.

That's what I assumed as well, and people tell me I'm fairly smooth (though it doesn't always feel that way to me). And a good pro racer who's tracked his 991 GT3 also told me it can be left on. OTOH, a friend who's one of the best drivers I know drove my car and felt what he considered excessive intervention during trailbraking (just as I do), and a few RL guys with a lot of track experience have had a similar complaint, so I'm not sure what to make of it.

In any case, I should clarify that I'm not talking about dramatic intervention with the car getting way loose, PSM lights going on, etc. It's primarily just pedal vibration during some (not all) trailbraking.

Some bumpy tracks are slower with SC on(most tracks).
Some smooth tracks it can help you sail through some fast corners to gain time.

No right or wrong, but I never turn it off unless I'm on a track where it slows me down or if it rains.

I leave it on at the track in my preped Cayman (same system) - it hardly comes on at all, I trail brake into 90% of corners and feel ABS often but not TC.

I had one TC instance yesterday where I came in too fast into a corner, got the car pitched in and started sliding into oversteer. I corrected with the wheel before the TC kicked in and all it really did was slow the car down maybe 8mph and bring the rear back into line. It probably would have looked a lot better if I had of left it off. That was the one instance in 4.5 hours of track time and it was on a corner I had been trying new lines, braking points etc all day.

I should add that I really didn't like the brake feel in the 991 GT3 on the track - maybe that's part of what you're feeling? It really just didn't feel right to me - way too firm, almost have to stomp on it.

^^No problem but you need the right driving clogs..
