426km/h 370Z

Not a legit run cuz the car is modded with Lv9 speed tunes, but still satisfying to watch combined with WMMT OSTs😜

Note: this speed is not achievable without modding/cheating (whatever you call it), current legit top speed with NOS boos is around 328-330kph iirc

Note 2: not recommended to mod your car if you are not done with all the NPC and stories, it basically ruin your game experience.
