Mercedes chose the softs because they felt it was better for their car, and they didn't have any new sets of usoutsid3r wrote: ↑Mon Aug 28, 2017 2:35 pmIt is very difficult to say but I think it is an element of both. I believe the Merc PU is slightly more powerful, but only just. I also think that the Ferrari was set up on the high-downforce/high-drag end of the spectrum. They could have certainly raced with slimmer front and rear wings (as they will probably do in Monza). But they were probably aiming on a 1 stop strategy for Spa thus the higher downforce would pay later in the race as the tyres would be in a better shape. Unfortunately we couldn't see if that would have worked due to Force-Indias' mash up. It is however evident how kind they were on the tyres seeing how they choose ultra-softs after the safety car and Merc choose softs. Vettel was also told to push as much as he liked as 'tyres were not an issue'. Also, the higher downforce setup could have been asked from the drivers themselves as both Vettel and Kimi tend to prefer a more stable and comfortable car to drive rather than raw pace.
All in all I am really impressed how Ferrari matched Mercedes on a high-speed track... lets just hope their 'forte' on high-downdorce tracks wasn't lost in the process
