Yeah, I never use rev match on the road either (just occasionally on tight and twisty canyon or mountain roads)...

When I started this thread I didn't own a 991.2 gt3. I had a gt4. In the gt4 I always used the rev match. I had some difficulty getting it just right on the street and on track it's a no brainer for me. One less thing to do and I can focus on my line and braking. HOWEVER on my GT3 I never use it on the street. For some reason I feel it's much easier to rev match in this car. Maybe it has to do with the wider engine rev range (I have zero clue) but I can do it perfectly and smoothly every time. And it sounds better lol. So on the street it's no aids. On the track or smokies mountain runs it's on though. Keeping up with Ryan R and Andy P is hard enough lol
I agree. Not sure why some people prefer the GT4 gearbox/clutch. The GT3 seems to catch better and rev match easier for me also. So a smooth and great manual to drive.

I will say I like the slicker throws of the shifter in the GT4 better but I don't dislike my GT3's gearbox. It just feels a little notchy is all.

Good way to hit a wall

I don’t see a point of using the sport mode on daily driving. Imo highway only. That way if you need to speed up fast you can. For the street I thought it was awful. I much rather downshift without it as it helps me stop much better. I’ve gotten use to doing it so much that if I time it correctly I don’t even use the brake. With sport mode on you don’t slow down as fast. Just my 2 cents

As mentioned in a couple posts above, you don't want to rely on engine braking whether on road or track. If you are finding the car slowing more when downshifting yourself vs. using Sport button, that means you are not manually rev matching properly and putting extra wear on the clutch and potentially unsettling the balance of the car. The goal is to be (nearly) as seamless yourself as the computer can do it for you. If this means you use the brakes more, remember that brake pads wear much longer and are much cheaper to replace than a clutch (not to mention potential body damage from a spin induced by poor rev matching).

I have a feeling this thread is about to take a major detour

More significantly, the wheels are spinning quickly (depending on road speed) and you are connecting them (through the clutch) to an idling (or nearly idling) flywheel which can easily cause the driven wheels to lose traction as they attempt to slow suddenly to match the speed of the flywheel, particularly if the road is wet, icy, snowy, gravel, etc. Even when dry, this is very poor practice. Do a google search on heel-toe downshifting and the necessity for rev matching on downshifts. Your car and your safety will both thank you.
Here are a couple videos to get a start:

I knew I should’ve gotten PDK.

Just use the Sport button all the time, until you learn to do it on your own (or not).
By the way, it's not necessary to heel-toe downshift in order to rev-match. Heel-toe is the fastest and best way to downshift on a track or if aggressively mountain driving, but you can take your foot off the brake to blip the throttle when downshifting. This way is much easier to learn, but means you need more room for braking as your foot is off the brake pedal for some of the time. Totally fine for relaxed street driving and will teach you the concept and feel of rev matching on your own. After that is comfortable, you can try heel-toe (preferably on a track, in a parking lot, or other safe space).
