@UKFanatic well that changes game plan a bit. I’ll dig a bit around this issue. Last I talked about it was in Spa; who knows what they know now…
@Muzzleflash @dam00r Squarer is better in straight line. the round has more lift, because of the zones of pressure on the round corners that spill over the top side, and for the bottom side. Round only has a small advantage in transient in the turns, but this is not substantial. This is my observation from CFD
