A Racing System for Unreal Engine 4 (UE4)

I need a racing system for Unreal Engine 4 that has the following features. LANGUAGE Blueprint preferred but if you think the core game logic would be better done in C++ I'm open to it. DESIGN A modular approach so the system can be used on any map. NETWORKING Networking and multiplayer is a key component to this project. VEHICLE SETTINGS AND PHYSICS - Ability to adjust maximum speed, acceleration time of each vehicle - The ability for each vehicle to have separate audio sound, impact/crash sound. - Car to respawn at last passed waypoint on crash or flip AI - Waypoint system to know the limits of the track and clever avoidance from other cars and players. - Start and finish line. Grid start system for all cars. CAMERA - Follow player car (behind car view) - Key to view backward UI/MENUS - Player car selection - Track/scene selection - Player UI with the display of current lap, position, time. - Online system to join the game. Only allow from 2 to 12 players per race. Racers that are not players will be AI. Always 12 in a race. OTHER FEATURES - Dead zone to respawn player if they go out of bounds - Speed boost to increase the speed of a car that collided with the boost speed object. This needs a setting for the amount of speed added and also the time in seconds the increased speed will last. This should add extra speed to the cars max speed, not be a set speed. - Option to control all settings so I can easily change them - Race mode: Option to have extra race modes later but for now, it will be lap based. Who ever completes three laps first wins. MULTIPLAYER - 2 and 4 players split-screen local multiplayer mode - Network: 12 car multiplayer ability using a matching solution. PlayFab, AWS or another option. Please let me know your ideas and thoughts. WAYPINTS  Check to make sure the player passes all points (can not skip one) CONTROLS - Keyboard, Mobile control, Console controller - Target device: Widnows/Destop/Consol with the option to consider tablets and phones later.
