Nissan Z Performance '23 (GT4 Replica)
Been working on this one for months using estimated specs before the real car was launched. Finally have power and weight numbers to go off of (which I half followed - read on) and mostly final visuals. After some necessary tweaks from the last physics update, I am confident enough to post this knowing it is about 98% finished. The only part that is not final are the gear ratios, and for those I am waiting on word from Nissan. Last I was told the current numbers are confidential and not final, but they will share once they are locked in. The ratios I am using are from a 6-speed Quaife sequential gearbox and require the following sequence to set: (if this doesn't work let me know)
- Set top speed to 800
- Slide 1st gear all the way to the left
- Slide 2nd gear all the way to the left
- Set 3rd - 1.565, 4th - 1.268, 5th - 1.051, 6th - 0.900, and Final drive - 3.538
- Return to 1st and set to 3.731, 2nd gear to 2.050
As far as the horsepower rating, you will notice that it is a bit lower than the real car. And the reason is that I wanted the car to match real life GT4 lap times. Using the 2022 GT4 America Watkins Glen event as my reference, the car's current settings would net you damn close to the P1 qualifying time set by a Pro-Am Supra GT4 at 1:54.882. In fact before I posted this I ran a few more laps to confirm and ran a 1:54.893. So to make it equal I had to limit the power significantly. You are certainly welcome to raise it back up to official spec levels but I cannot guarantee it will retain the same handling characteristics.
Weight is set to official specs from Nissan + my body weight. If you want curb weight of the car alone, set to 1,410kg (3,108 lbs)
For body mods, add front lip only. (no wide body) Rear spoiler small.
As-is it is very fun to drive and easy to correct when the rear steps out, which it does not do often unless you are pushing really hard. Sounds great, handles great, almost looks the part.
Here's a quick hot lap video at Maggiore West Circuit:
Enjoy!
