Just like many other models, the Saab 9-3 had a variety of possible disk rotor sizes. You'll need to know the correct size to order when replacing discs.
One option is to jack the car up, remove the wheel and measure, but on models newer than 2006, there's a much easier way.

There's been a fair bit of controversy over DNS-over-HTTPS (DoH) vs DNS-over-TLS (DoT), and some of those arguments still rage on.
But, DoH isn't currently going anywhere, and Firefox has directly implemented support (though it calls them Trusted Recursive Resolvers or TRR for short).
Although DoH offers some fairly serious advantages when out and about (preventing blocking or tampering of DNS lookups by network operators), when left with default configuration it does currently come with some new privacy concerns of it's own. Do you really want all your DNS queries going via Cloudflare? Do you want them to be able to (roughly) tell when your mobile device is home, and when it's out and about (and potentially, also your employer - if they own the netblock)? The same questions of course go if you use Google's DNS too.
That, however, is addressable by running your own DNS-over-HTTPS server. This also has advantages if you're trying to do split-horizon DNS on your LAN, so I'll discuss that later too.
The primary purpose of this documentation is to detail how to set up your own DoH server on Linux. The main block of this documentation is concerned with getting a NGinx fronted DoH server backed by Unbound up and running, but will also discuss the steps needed to add Pi-Hole into the mix.
