I actually wonder if that's true anymore, even around Monza. The engines are nowhere near as powerful as they used to be in the V10 days and of years gone past - and the increased downforce helps you carry more speed through corners AND have better traction - so that's a double whammy of help on entry to the straights, especially from the medium speed Lesmo 2, and the faster exits of Parabolica and Ascari. Another unexpected help of a higher downforce (and therefore more aggressive gearing, albeit to a lower top speed) is that you're quicker between the first two chicanes - better exit, and the cars with a low downforce setup never hit top speed around Curva Grande anyways. Watch back to 2011, and Vettel was the fastest car bar none through Curva Grande, as he had better traction onto the straight, and was hitting his top speed (while others couldn't hit even Vettel's top speed)
