We have 4 customer slots available for teams from rookie, and perhaps even from Pro. While the engine stats aren't currently maxed out yet, we are planning on aggressively developing them to bring them up to pace, and some tracks already have great stats, especially for rookie and pro teams. The engines will also always remain at 500k, no matter how good they get in the future, the prices will remain the same.
Feel free to apply, and send me a message if you need specific attributes as strength at a certain track.
(Ps, the engines will be developed to make the car strong in leagues without refuelling)
