Blowers for muscle cars / Drag

I think that this game has done things correctly, but I wonder why the muscle cars can't get any blowers with the exception of the Camaro of the main story, I wonder if this could be a possibility for customization in the future. 

And of course I wonder as well if we can't get Drags like of the times of Underground 1 and 2, I consider that a modern version of it would sky rocket this game into more progress
