I have a pretty bad computer (seriously, you could probably buy it for 50 cents if it were available at the dollar store) and I can run the car without any lag. I tested the car a lot before releasing it, without invincible mode, and nothing breaks by itself most of the time. When it does, it's just the little front wing, and that rarely happens. I can't see it "easily" breaking unless you're trying to run it into a tree of something this is definitely not a Batman Tumbler. Adding armor takes away from the aesthetics of the car in my opinion, it's suppose to be relatively sleek, not built like a tank. Regardless, thanks for giving it a try! Happy gaming
