Porsche 911 GT America - IER Simulations - USCC Mod 1.0

The final installment of IER's USSC mod is finally brought to Assetto Corsa.

  1. mclarenf1papa
    IER Simulations is proud to finally present the official conclusion to the USCC mod, the Porsche 911 GT America.

    Development Team:
    mclarenf1papa - physics, project manager
    Patrik Marek - 3D modeling, textures, liveries
    Le Sun Tzu - liveries
    Fonsecker - sounds, reference material
    Gary Paterson - driver animations

    About the car:
    The 911 GT America was built exclusively for the United Sports Car Championship (USCC) and its GT Daytona class for the championship's maiden year in 2014. Based on Porsche's 991 Cup car, the GT America was fitted with a more powerful 4.0-litre engine and new aerodynamic appendages to better match the car's performance to the GT3-based vehicles of the GT Daytona class. One of the most affordable cars on the grid, the GT America saw great use and great success in the USCC until GTD was reformatted in 2016, rendering the car ineligible for competition.

    Known issues:
    - Car is very bad over uneven apex surfaces like curbs (tire model issue with AC - worse on some cars than others). Exit curb behavior is okay.

    Just had my first online race with this mod and I loved it. It's certainly one of the best handling mods out there for AC. I find the longer braking distances just as another challenge, and certainly not an issue with the mod. There is a small graphical glitch just with another car's door behind not rendering in the virtual mirror.

    Wow! What a car. It's so immersive. The feel, the sound, everything. I love the tailhappiness, but the brakes lock up a bit too easy. Thanks! Cheers Robin

    I love this car. I'd say it's among the very best of the best in all of AC's mods and original content. Its physics seems absolutely perfect to me. and it's a car whose handling is a lot more interesting than a GT3 car, and it's a massive improvement on the Kunos Porsche Cup car .
    I am, however, finding the brakes very difficult. I lock them up a lot. I wonder if they could be set up differently to ameliorate this.
    Thank you very much! This is my favourite car right now and will be for a long time.
    I'll be buying your other content :)

    I really like the feel of the car, but could you perhaps remove the driver helmet when in VR? It's very distracting.

    Really, really nice mod. Looks, feels and sounds like the real thing. But if it feels a little tail happy, check the default cambers; they look insane to me. I reduced them to more conventional values (like -2.5/-1.5, actual, F&R) and it seemed a lot less twitchy.

      Camber values are accurate to the real car.
