This is my contribution especially for noob guys who want a " safe " run despite the weather.
I don't have ( yet) my gt7 cause i can't find any ps5 yet.
But i play with a small guy ( 11 years old ) and " help " him to grind in his ps4 pro.
Since he was on a trip for holidays he gave me the console and the game to " work" for him till he get back.
I use to grid here using red bull junior but thanks to a guy answer somewhere in a vid i follow his suggestion.
The car is the Gtr nismo 500 16 motul autech .
Just by intermediate tyres use this tune and you are " done" whatever the weather would be without the need of pit stop.
Important to use FM 6 from the beginning to serve you easy for 6 or 7 laps.
After 25 plus times of running, after collecting all the silly penalties that exist my thoughts are :
Is totally safe no matter the weather,only at torrential rain you must be careful for aqua planing close to 210 khm. or more , just lift off and keep going.
The benefit of heavy rain rewards you for a 6 lap race like this.
The car is quite slow compare to others but i find interesting to challenge my self " searching" for the best lap especially when rain doesn't show up or when is getting dry after .
So startin at 4.32- 4.34 i went down to 4.26 low .
Its extremely " challenging" at the last part of the track cause you can go flat out all the way while silly penalties awaiting.
I had a lot of fun out of it challenging my self leaving aside the dirty work of griding
Many thanks to the guy suggest this using the name Dinocaster .
The only thing i change to his tune was to lower front and rear height leaving the rear higher than the front to help me a bit on top speed.( not by much but helped the " cause" ) .
When os ready ill post my best run lap.
Hope to help someone.
