That's not to say you won't get a benefit from bigger brakes. For one thing, brakes don't just stop the car, they first have to slow the wheels which have a huge amount of inertia at speeds, and while they are indeed connected to the road, they need to be considered as part of the equations. A bigger brake will offer more braking torque which will make that mass more transparent. So what, you might say, you'll still lock the wheel. Well, the bigger brakes also allow you to slow the car hard more frequently and furthermore the bigger effective lever makes them easier to modulate at threshold. If none of this were the case we'd all be driving around on 9-inch discs and call it a day.
That doesn't answer the question of will there be a significant upgrade going to the SVT setup, but it's true nonetheless.
