Will just changing the rotors really affect braking, maybe just brake fade. For more stopping power you need to upgrade the calipers, I might go for their new Version 2

I think that at the track or where you see repeated braking that they will just over-heat the stock calipers. All Calipers should have the same overall clamping force due to receiving the same brake fluid pressure from the brake cylinder.

The performance difference should arise from how the caliper design changes the distribution of the force. With 4 (or more) pot calipers, the pressure of the brake fluid gets distributed over a wider area on both sides of the rotor instead of a single piston on the back side of the rotor. The design of the caliper has a big effect on heat distribution, e.g., the RS6 team ditched the 8-pot OEM calipers for 6-pot Alcon racing calipers due to heat dissipation issues. So, it's just not the number of pots that dictate performance.

In any event, you will see a big improvement with bigger rotors due to the increased leverage, but do not expect rotors alone to provide the perfomance benefits of both larger rotors and multi-pot calipers. You need both for a complete solution, but upgrading either one will improve performance in decreased stopping distances and/or decreased fade in repeated use.
