Gosh. your post took some reading.... :-)
For sprint/hillclimb use (as this post is in the "Speed" section), our primary requirement is to be able to quickly and easily review the run that we've just done. So its important to catch the information we need using hardware alone, so talk of using a separate sound recorder and post production is inappropriate in this instance.
I normally review a each run soon after the run, often simply on my phone. I'm looking to see how I can improve my next run. I started out using a bullet cam and a separate recorder at just 640x480 resolution, which is actually quite adequate. Actually, I feel that sound without wind noise is far more useful that image quality.
Something else you may wish to think about is using some analysis software along with one of the GPS enabled GoPros. RaceTechnology offer a standalone GoPro package:-
'not as useful as a full datalogging package like I use, but may still be useful to understand your performance.
I think I asked before but forgot the reply, how do you attach the iphone?
I must confess, I hadn't noticed what section the post was in
If you're just after something for analysing a drive in the champs Justin, then maybe a phone you already have is the best/simplest option? For attaching to the car, securely, how about a PeakDesign phone holder with a SmallRig clamp.
For analysis on-the-cheap you could do worse than RaceChrono (17 quid, IIRC, versus the 59 quid for the GoPro option mentioned in #22). If you want to get better GPS data for a more accurate view, I'd recommend splashing out on an external, bluetooth, GPS device like the SkyPro XGPS160. It works seamlessly with RaceChrono.
Heading more towards vbox territory but without quite the horrendous price tag, is it worth looking at the Garmin Catalyst? (never used it, couldn't tell you if it was any good).

Hi All, I must also confess that I only realized this was a Speed related post once I was most of the way through writing my last response. But hopefully its still useful to some.
Mark (mph) makes some good suggestions I think - he and I regularly discuss cameras/tech in cars and I know he creates some great video and analysis from them.
If a dedicated camera is still what you're looking for I can offer the following further thoughts on action cameras...
Firstly a general thought: The GoPro 8,9 and 10 don't need a cage to attach them to anything. They have the GoPro"prongs" built in. The DJI Action 2 has magnetic mounting but I probably wouldn't trust it to attach to a roll-over bar. The DJI Action 2 mounts (non-magnetic) are good though. The lack of a cage on the newer GoPros really helps when handling the devices (IMHO). However, the battery doors are a fiddle and getting the sd-cards in and out of them requires patience and decent nails!
Second point, the GPS sampling speed of recent GoPros is higher than it used to be. It's now 10 times per second (UPDATED: thanks Mark-mph), so its able to show better location at higher speed. It still has accuracy problems, but its now higher termporal accuracy and low spatial accuracy! I haven't done high resolution GPS testing on the GoPro 10 so can't comment on how accurate the GPS is now... but i hear its better than it used to be.
So I guess (as you know) you have two options for reviewing video from an action cam quickly and here are some of my thoughts:
1. Review on device.
2. Review on a Phone/Tablet
If you’d like any other tests or comparisons doing then I can have a go.

Neat interaction with RaceChrono and GoPro…
Updated #26 to include GoPro7 transfer speeds.
BTW... I'll be at Gurston Down on Sunday to watch the fun. I'll have some GoPro's and DJI Action 2 with me if anyone competing wants to see them. I'll also pack some 360 cameras if that's interesting to anyone.
Just a point to consider : for racing we mandate that all competitors carry a camera so the Clerk of the Course and the Driving Standards Team can review footage after any incidents / protests / complaints. Originally most people used GoPro-style cameras. But the number of failures was scary - about 25-30% of cameras didn't record because (1) "I forgot to turn it on", (2) "the battery ran out mid-race", (3) "It somehow switched itself into photo mode instead of video mode", (4) "the memory card filled up", or (5) "I did everything properly but it just didn't record" (the usual one).
So now cameras have to be hard-wired to the car's power, and turn themselves on automatically with the ignition (or at a low minimum speed). We get very few failures now.
That basically means a dash-cam, but surprisingly the number of dashcams available that are suitable for a Caterham are small. INNOVV and Viofo are are main suppliers (noting that some of the INNOVs don't like having power turned off at the kill switch, making them unsuitable), but when my Viofo failed I bought a cheap kit from Amazon which is surprisingly good once I'd added some foam to the mounts to make them more stable.
You don't get 4K at 60fps, or image stabilisation, or any of the other bells and whistles that you get from GoPros. But you do get solid footage which doesn't fail to record.
