Deliberate mistake: Steve is not superhuman, but he could see and almost (Diana whips it out of the way first) dodge a bullet at the beginning of the car chase. (01:21:55)
Deliberate mistake: When Diana and Steve visit the Mayan guru hideout, they find an issue of Pro Wrestling Illustrated with Jerry Lawler on the cover. It's the August 1984 issue though, that couldn't be there since it's still early July. The prop department knew what they were doing there though; if you look at the cover, you can see they modified it and it actually says July 1984. (01:29:40)
Answer: When Barbara Minerva wished to be just like Diana, she was granted the same strength and powers as Wonder Woman. Barbara additionally became less humane and even more powerful and dangerous after morphing into "Cheetah." Diana needed the armor to outmatch and defeat Barbara. She was also expecting to fight a multitude of soldiers to get to Max. The armor was originally Asteria's, who needed the extra protection when she battled an army to save the other Amazons.
