Rev match
Have a 15 C7 manual and am trying to understand why one would use rev match what are the advantages or disadvantages? I have not had the car that long and have never tried it.Thanks in advance.

Does exactly what it says, automatically matches the revs when you downshift or up shift to make a smooth transition when engaging the clutch. I don’t really use it much street driving, but it would probably come in handy on a track.

Love the Rev Match
I use it for local and spirited driving all the time! I leave it off briefly while the engine/transmission warms up and I turn it off for longer highway cruising.

One of my favorite features. Really smooths out up and down shifts. I used to do it occasionally with my 63 convertible, but I do believe it makes shifts easier on the torque tubes as well as the clutch when driving my 19 GS M7.

After breaking my right ankle twice thanks to blocking shots when I played hockey, the flexibility is no longer there. Makes it tough to heel/toe on track with the stock C7 pedals so I use Rev Match to its full potential. On my C6, I had a modified gas pedal to help with reach but there's nothing like that for the C7.

I use it every time I drive the car. It's become habit to activate it now..... start, seatbelt, rev match, parking brake, go

I never use it, though I've tried.
Rev match is not preemptive and therefore, has no idea what gear you're in until the shifter is in the gate. I've learned how to get through the up or down shift pattern quickly enough to to live without rev-match. It reacts far to slowly for my liking and I've had far too many late blips from it.
I congratulate the guys that can use it, but it's not for me.

Its a neat feature that works the way its supposed to. I dont use it for DD. I get a small thrill when blipping the throttle for a perfect downshift.
I have used it at autocross/track. One less thing to think about when youre a novice like me.

The point of rev matching is to get all the rotating assemblies rotating at the same speed. It keeps the balance of the car as well as saves on wear and tear. I do it with out using the feature but got in the habit long ago.
A small example for the non track guys. If you are slowing to go into a corner and need to downshift and don't rev match, the car will dive forward and take all the weight off the rear wheels. That can make you spin out. Hope that makes sense. Obviously not an issue on the street unless you are really pushing it, but it does save a lot of wear and tear.

I use it all the time.
On other cars with less weighty assemblies and engines which spin up faster I never missed it, but with the C7 it really does make the shifting smoother. It also reduced the clunking before I got my diff fixed.

When I was at a local event where Harlem Charles and Kirk Benton were introducing the C7 for the first time, Harlem made a point about the new rev match feature. My first question to was could it be turned off, as I automatically heel & toe (muscle memory) for downshifts.
When I got my C7, I left it on for a while, but eventually turned it off, as it interfered with my heel & toe throttle inputs. Now, I never use it.

I generally don't like having Rev Match on when I'm just casually driving around. It's annoying.
I normally only use it when I'm blasting down a twisty road at well above the posted speed limits. I love downshifting as I go into a corner, and stomping on the gas coming out of the apex. When you do that at over 4,000 RPM, it's nice not have it rev match for you. I'm not able to heel & toe. At high RPM's, the automatic Rev Match sounds awesome.

I am the OP and I will say I tried it yesterday I can live without it. I don’t see any benefits other than sound. Maybe I’m missing something.I think the heel/toe method has to do with keeping revs up when you’re shifting especially downshifting maybe someone more knowledgeable with regard that can chime in.
