I'm still not going with aero, as much as you push the boardboards as a fix-all solution, yes, they need development (new BB parts coming for France, btw) - as does the rest of the aero, but it's not too bad in mid and high speed corners, it struggles at low speed, heavy traction circuits, where mechanical grip is far more of a factor, in both high and low downforce configs.
They have a fundamental kinematic/compliance and/or tyre conditioning issue imo.
It's not a fix all solution, it's an area that needs fixing to get the most from the chassis. I know they have really good braking stability and downforce in the mid high speed corners. What's lacking is diffuser instability at low speeds, so they have to compromise by running more wing which hurts top speed. When their diffuser is more stable at low speeds it lets them run less rear wing and the car will work better at low speeds. Whatever chassis or platform deficiency doesn't help, however I maintain, the aero is a big reason they struggle in low speed.
The good news is that it's not unfixable, and other than the bargeboards the car is extremely good in most every aspect. It won't make them faster than everyone but bargeboards along with the front wing are critical for sealing the diffuser.
Again I'm not claiming a cure all, just that developing this area is their best move because it can bring immediate gains, and it will stay relatively the same for next year.
That's quite interesting. In your estimation, how much do you think they can gain in tenths of a second from development on the BB areas in the short term?
At least .3 and as much as .7 just there alone.
They don't have to copy, just draw inspiration. Ferrari, and Red Bull have the right idea, and best execution on the grid, Renault and Mercedes made critical mistakes but their solutions are interesting.
The reason this area makes such a big difference is because it works in tandem with the front wing to seal the diffuser and floor. The rake to the diffuser isn't as important as the rake between the bargeboards and the front wing.
So if you make the bargeboard like a wing which helps the front wing, it makes that area much more powerful than using the bargeboards and side pod undercut to directly seal the floor with vortecies. The vortex integrity happens at too high a speed so this philosophy is useless in slow corners.
But if you turn this area into a wing you gain more low speed downforce, but loose a bit of mid to high speed downforce. But who cares it means more low speed grip and less drag at speed. True it takes some re-balancing of the car, but it's just setup related, nothing fundamental has to change.
