I just installed the Volvo load carrier rails on our 2019 XC60 Momentum. Super easy install, and I like the key lock at each corner. My question is regarding the positioning of the rails on the roof. The instructions are really vague, and leave a lot of leeway. Can anyone who has these installed let me know if mine looks correct, or if anyone has found an optimal spot for them for best use, and low wind noise?

I attached a few pics to explain where I put mine better, basically from the start of the front rail I am 20" to the front of the key lock square. From the end of the back rail I am 17.5" to the back of the key lock square. Between the rails I am 30.5" measuring from the middle of each key lock square. Thanks in advance! Scratch that looks like I am not allowed to post pics for some reason???

True, it's about what you have on top and if you can still open the rear hatch for me. Only exception is when my kayaks are up.

Not really related to the placement of the cross bars, but make sure you remove the cross bars if you're driving around without any load on the racks for extended periods. These things harm fuel economy pretty badly, even if you put one of those angled aero plates over the leading crossbar. I'm always surprised how many people drive around daily with these installed but with no load.

Im sure you are not following these people around to see how much daily driving they do with rack on or off, when they load the rack and why is it still on their roof after they are done with their activities.
I keep mine on almost all the time, and with new car i monitor my economy just for kicks. City economy is barely impacted, highway is somewhere in the range of +5-7%. Roof box adds around 3-5% more same as a surfboard in a bag.
As to why i keep it on my car: i use it at least 3 times a week, but i do most of my kilometers unloaded due to commute... Taking it on and off 6 times weekly makes no sense, only time i take it off is when i have multi-day highway trip that requires no rack.

Back on topic (maybe slightly off as i have V60): my rear is right above C pillar, then i measure 80cm forward and mount front one...

For those with a cargo box, I've found that placing the forward bar as far forward as possible (within cargo box and rail spacing limits) helped a ton on a US cross-country trip. I have a Yakima Skybox and was getting bad vibrations around 70mph, which is ok-ish on the East Coast with lower speed limits, but by moving the front bar max-forward it ever so slightly lowered the nose of the box and I was able to maintain 85mph before the vibes started again. The extra 15mph really paid off starting around Iowa/Nebraska. Don't ask about fuel economy.

My Audi had keys in the roof rails to fit the bars in exact positions. The front bar was keyed left to right as well as only fitting in the front. The keys ( holes in the roof rails) also stopped the bars from sliding on the rails.
It seemed like a very cheap an effective solution.

Exactly, and BMW has a very similar system as Audi

I'm glad Volvo allows us to be responsible adults and install the load bars through almost 90% of the length of rail. It allows the customer to tailor the spacing to fit the needs of the loads. Looking only at Yakima crossbar spacing limits, you would need a spacing of precisely 32" to fit all but one of their current products (https://yakimasupport.zendesk.com/hc/en-us/article_attachments/115000268988/Crossbar_table.pdfPDF source). Which manufacturer wants to check the major cargo brands every time they spec a new design? I'm sure the other brands have products that fall outside that range too. I don't have pictures of this, but what if you want to rent something very large like an extension ladder? Is 32" enough? Heck no it isn't. I put a bar at the very front and the very back to balance the load. Having that versatility saved me from having to rent a truck for 2 days.
