if you are going to track your car, or hoon it somewgere at a very fast pace, on a regular basis, then yes, go and buy bigger rotors, but as I said, 99% of people will be better off saving money, and just buying better quality stuff for their existing brakes. You can replace your fluid to the best stuff, with the highest boiling point, (not sure if there is anything better than 5.1, I'm sure someone will say), but just plonking on bigger rotors won't make you brake any quicker.
Be careful with your ratings DoT5 is silicone based but 5.1 is glycol based(traditional sort)

You can't just change DoT4 fluid for DoT5, the fluids are of a completely different composition, if you want to change fluid types, you'll need to drain all the DoT4 out and flush the entire system with methylated spirts, allow to dry the refill with the new fluid otherwise they'll mix and you wont get the full benefit of the new fluid.

Also DoT5 isn't hygroscopic, so you wont need to change it after 2 years because it doesn't absorb water.
