Beta The Realistic Derby Project - Demolition Derby Mod 1.5.1

A realistic demolition derby mod built by a real life derby driver.

  1. NoDakSmack

    The Realistic Derby Project is a demolition derby mod made by a real life derby driver. The goal of this mod is to achieve a realistic derby experience with parts inspired by the parts we use on actual cars. With this mod you can build to your desired set of rules, from stock, to limited weld, to full weld, with many different part variations and options available so you can build your car how you prefer.

    Currently the mod is a work in progress! And I plan on continuing progress on this mod as long as possible. So much more to come!

    This mod is being built in collaboration with Demolition Derby - The Fairgrounds by Bidwars, which offers a scenario in which you can derby against CPU driven cars! At this time, these are not yet built into one another natively, but you can still play using my mod in his scenario if you simply save my vehicle configurations overwriting the titles of his presets such as "pro_moonhawk(1)" which will replace that moonhawk slot for the Pro class. Make sure to replace all the slots of this class if you want the CPU to use my cars too.

    The Cars
    Each car has been heavily modified to have a more realistic frame and body, and each offers different strengths and weaknesses. Many of them are built to resemble real cars in the way they bend and how they might be set up. Presets can be found saved for each car under a name such as "RDP Stock Derby Moonhawk (1)"

    Bruckell Moonhawk
    - a full framed car similar to a 71-76 GM sedan.
    Gavril Grand Marshal - A tilted new iron car built like a Crown Vic.
    Burnside Special - A full framed 4 door... probably most similar to a 58-64 ford?
    Gavril Bluebuck - A cross between a 60s mopar and a suicide Lincoln

    1987 Ford Crown Victoria
    - A custom car built for the mod! Highly realistic to the real deal!

    Pickup class - coming soon

    The Parts
    Just like a real derby, you can build each car to a specific set of rules that you prefer, whether it be stock with few extra parts, or a mod class with engine protectors and frame plates. Some parts have/will have variations, such as different style headers, halo bars, trunk setups, rear ends, various homemade and loaded bumpers, and many more. Here's a list of parts currently in the game (which may or may not currently be on certain cars). The list of planned parts is much longer, and variations of existing parts will come as well, and many of these are still being worked on or tweaked as I test.
    • Cages - WIP, if you're experiencing lag with the moonhawk, try removing its cage. The current cages are unnecessarily complex and may cause lag, and a much simpler yet effective design is being worked on. Cages will have 3 parts, the main part, halo bars, and gas tank protectors. In the future, the main cage will be built directly into the body.
    • Derby Frames - Currently in stock and limited weld variants for each car. Every frame has been heavily modified to have realistic strength.
    • Derby Bodies - Every car gets multiple body variants, also with modified or rebuilt structures to bend properly.
    • Bumpers - Loaded and homemade bumpers that won't bend are welded directly to the frame. The hardness and geometry of each bumper might affect how the frame bends differently. There are currently 2 front bumpers to pick from, a loaded Moonhawk bumper and a homemade bumper. Many more to come.
    • Engines - Purpose-built derby engines are typical in today's sport. Every car has a mildly built Chevy 350, with more to come. They withstand the stress and heat better than stock engines, while offering more power.
    • Headers - 4-in-1 headers are available in each car. Different styles to come.
    • Welded doors
    • Trunks - Tucked trunks will offer a more predictable roll, while dished trunks will give more strength. Be careful though, if you aren't using parts such as hump plates, rear window bars, or extra body mounts, a harder trunk might put too much stress on the frame humps.
    • Gas Tanks - Relocated to the interior of the car.
    • Creased fenders - Creasing fenders will offer more strength and a few more cool-guy-points
    • Extra Body Mounts - Cars benefit from the frame being tied into the body as much as possible. Extra body mounts will stiffen up your car slightly.
    • Distributor Protectors - A protector on the back of the engine. It might also reinforce the car since it's so close to the firewall.
    • Suspension - Front suspension modifications to offer a stiffer spring and taller bumper height, as well as stronger suspension components.
    • Radiators - Some of the default radiators don't handle the stress of derby engines very well. Aluminum derby radiators will offer better cooling.
    • Axles - Different axles such as Mopar 8 3/4. Reinforced rear ends in the future.
    • Hump Plates - Plates to help the humps from blowing.
    • Hump Chains - Chains from the axle to the top of the frame. Helps hold the rear end in place.
    • Threaded rod through core support - Body mount replacements from the frame to the hood, while also reinforcing the core support.

    Want access to my mod as I develop it?
    Patrons get regular updates to my mod as I make it, join along, have a say in what I do next, and watch the content grow every week!

    This mod was developed under a i7 7700k, GTX 1070, 32gb ram. Frame drops may occur but shouldn't be significant in most cases; if you experience significant frame drops from certain parts, let me know along with your specs!

    I like the Crown Vic. Could you add a stock version of that car? And maybe a police version? I think those would suit it well.
