I'm not quite certain what you are looking for. If you are looking for an F1 car that's 1:1 with the technical regulations then you will never get it because the game can't do certain things, and I'm not certain if any modder is willing to put in that amount of work to get as close as possible. If you are just looking for something to look like an F1 car you have so many options to choose from. Formula Pro, McLaren MP4-13, Formula ISI, Formula Hybrid 202X, FSR, GPVWC... and likely a plethora of other mods that I don't know about. You are free to grab the GPVWC 2022 mods and the 2023 BETA versions on their Discord server.
