They are all stock, i only added oil change for the car i bought used that needed an oil change, no tire change except for the RUF CTR yellow bird i added comfort hard in front to tame the oversteer. i did not played with any ratio.
I know nurburgring a lot as you can see i did a lot of laps lol
i have all the ghost replay saved, cars that hit redline on top speed you can keep throttle at 75%(for example) and you can squeeze may be like 2-3mph more. at WOT it will bounce the rev limiter too fast and go slightly slower...
same thing for acceleration, some cars have a 9500redline but dont need to go that high you lose power, i try to stay in their powerband.
I also used the H shifter for manual cars and paddles for automatic cars.
It would been useless to mod them to go faster too, i wanted to do an accurate database for fun, but i seen the thread and decided to post.
I dont know what to say for the times, i did the best i could, some required a good amount of laps to master them, some 2 laps was enought, or i didnt liked the feeling so didnt bother doing better... Some were a pain just getting a clean lap...
If theres a way i can send you the ghost replay i dont mind.
i only do that to have good races, i can see which cars make some close race.
