C7 ZR1 M7 or A8 for track?

Le Mans Master
I tracked my 2018 Camaro ZL1 with A10 and that transmission was shockingly fast (arguably better transmission than the A8) around the road course. It was always in the right gear and had no lag whatsoever. It's faster on both the drag strip and road course than the M6 ZL1. I am sure the A8 has a similar advantage (albeit not as much) over the M7, but I ordered the M7 anyway for my ZR1 ZTK. AFAIK, this is the last of the FE, Manual transmission RWD ZR1 Corvettes. I wanted the fun of shifting in a car that will eventually be a classic to hold onto - even if it is slightly slower.

I had, and still have the opportunity to buy two different A8 ZR1's (one is 10K under sticker and the other 8K under) and chose to pass on both. I don't track my cars and just like to play a bit on early morning back roads etc. For me, it's the fun and pleasure of driving and I just don't get that from an automatic. I came close to buying one of the A8's but knew deep down it wouldn't work for me.
Good prices.
Ordering an M7?

It’s a different transmission altogether. Better design with faster shifts in auto mode. Always in the power band. Iirc the only reason it didn’t make it to the C7 was fitment. Otherwise it’s a big upgrade. I’ll post my track video when I get home. It was always in the powerband and had PDK level shifts.

Nobody local to me has an allocation and I haven't really looked elsewhere. Have never ordered a new car, as I like to see what I'm getting before pulling the trigger. If the right car comes along, I'll do it but I'm not aggressively looking. The only sure thing is it will have to be 3ZR with an M7. BTW, good luck with yours. Look forward to seeing pics very soon.

I find that difficult to believe. It does depend upon what mode you are in. In track, and especially mode 5, I think you will find it pretty darn quick. As far as in the power band, the transmission 'learns' very quickly. A beautiful system. I wouldn't knock the A10 because I have never been in one. But I have been in mercedes and porsches that have the PDK/DCT. Have you ever been in the ZR1 at the track in track mode and sport 5 mode? If not, I think you will find it impressive. As far as on the street in tour mode, the ZR1 is not nearly as quick shifting as in that track mode.

A PDR video would be better,it tells throttle,brake,steering angle,gear plus a lot more data Do you have a 1LE car

Not sure why anyone would argue the A8 is better or as good as the A10.
The A8 is known in every GM platform for issues (trucks, Corvettes, Camaros, CTS Vs)...the A10 is known NOT to have the issues.
The only reason the A8 is in the ZR1 is because the A10 will not fit, it has NOTHING to do with capability.

As far as those articles there is nothing about the comparison to the A8 except the chart showing ratio differences. You stated that the A10 shifts faster and is in the powerband more. I don't see that either. The LT5 has a fairly wide power band. Also, the articles I have seen state the A8 is faster in shifts than the PDK's. As far as the comparison to faster shifts than previous trannys it appears to be comparing previous autos available in the camaro. Both articles are from 2016. But, if you know of a direct comparison to the 2019 ZR1 A8 that would be interesting. As far as fit of the tranny, the size is the same as previous autos.

Just my $0.02 tracking/racing for 20 years... the rev match is anything but a joke/gimmick. It's amazing and works perfectly. I don't bother heel-toe shifting anymore. A big benefit for me is I can now brake with my entire right foot vs. the ball of my right foot and trying to roll over my foot to blip the gas. Being 6'3" I can't do a "traditional" heel-toe where you rotate your foot way over swinging it from 6 to like 4 o'clock. It's allowed me to brake with even more confidence which means harder and later.
