Longer Practice and Quali Sessions
This mod lengthens the qualifying sessions by 50%, and the practice ones by 100%. For those looking for a more "realistic" session length.
The AI also should be unaffected. In all my tests they kept specific tires untouched, so you could work out what the are planning to do for stops during the race based off how many and of what type they used during the extended practice and quali sessions.
You can get at least 3 flying laps on the long quali session setting. More then enough time to test out some fine adjustments before you crank it up for a real time on a fresh set.
Be aware, you must start a new career for this mod to take effect.
