Well they must have something as they're the only team that have had a mid to low nose for the last few years and it's been keeping them at the front. I just find it strange that having a step like that it would act like another wing at high speed, the wind will simply hit it like a brick wall and push the air over the top of the driver which IMO would affect the drag on the rear wing which could I guess give greater top end speed, but then that would negate the point of the DRS.
