Can we get some different brake rotor materials instead of just the plain old steel ones? I am not sure if the game already has different rotor materials in it (I searched the Jbeam files to no end). We could have the basic Iron/Steel rotors for just base models but for things like super cars and race cars there should be aluminum brake rotors or even better yet carbon ceramic rotors. Also being able to change the amount of piston calipers. Instead of having a two pot piston caliper there can be three, four, or even six for extreme braking needs
