Equally as we’ve identified over and over is that the top chassis (with that I mean FER/Merc/RB) are able to carry much more speed through sections like Sector 3 in Barcelona.
I’m not sure whether it’s top end “peak” DF related in conjunction with suspension?
Or perhaps its a problem inherently baked into the chassis and possibly to do with how well you can integrate the engine package for optimal CofG and CofP (aero).
Maybe a combo of all of the above
