You should be beating it on the highway. It wont beat it on a drag race if that is what you are doing. There isn't any specific parts that I am aware of, I have stock rims and a spoiler though
So why does Mine not beat a schafterv12? I have spoiler and all that. Playing on ps4 btw. Does it need anything specific
I caught and passed several Super cars already going from Paleto to LS.
