FRONT WING SPAIN


Different bridged element (already explained by Tomba ) . The wing’s wider second flap changed to a smaller one

[bar555]

FRONT WING - TURKEY


The wing’s second flap was once more wider for more downforce , compared to Spanish GP version

Thanks for the hard work, bar555. I'm sure everybody around here greatly apreciates it.

I have a newbie question, by the way. Lots of road legal sports cars (like Porsche 911s) have perforated brake disks (steel, I don't know about ceramic brakes). However, from your amazing pictures all F1 teams seem to be running ventilated, but not perforated, disks. Is there any explanation for this?

well perforated disks are actually cross-drilled rotors, they are design to improve cooling without a brake duct
F1 cars have brake ducts that have air coming out from the centre to the edge of the rotor inside the rotor while rotating. Having the holes will only reduce the amount of air in the inside of the rotor and reduce brake cooling. And also high loading on the rotor may result in cracks, if the rotors are drilled.
Drilled rotors are mostly used on street performance cars which have no brake ducts and does not undergo such extreme loadings for a long distance and time.

Given the selective closing of the right chimney on occasion, is it a safe bet that the ECU is somewhere on the left side, necessitating extra cooling on occasion?

This something that only Scarbs could tell ,

My opinion is that the lubrication system's cooling needs require an open chimney in hot races



BARGEBOARDS DETAILS


1. Additional triangular turning vane connected to the vertical bargeboards, to improve airflow efficiency around the bottom of the car

2. This second triangular fin adds some downforce, but its main function is to clean up the air flow to the rear of the car, making for more stable handling

3. Vertical curvy connection between sidepod panel and bargeboard . The pyrpose is to direct air around the sidepod
and onto the rear wing

4. Horizontal upper profile , an air channel is created by this feature

5 & 6. Horizontal profile, to the bottom of the barge boards . This create a better seal between the bottom of the car and the ground, diverting airflow underneath the car more efficiently and generally improves the car's front-end sharpness

7.Small cut

8.Smaller bargeboards inside the front suspension . These front bargeboards have a bigger influence on the car's aerodynamic balance than the larger ones in front of the sidepods. This is because they directly receive the airflow passing through the front wing, and divert it under and outside the chassis to increase the efficiency of the bottom of the car

I thought (for some reason) that the ECUs, data loggers etc are located somewhere behind the front suspension.

FRONT BRAKES - BAHRAIN


1.Inner sheilds

2. The fin inside the inner shields of the front wheel beneath the brake cooling ducts help to reduce the turbulence generated in this area by the wheels' rotation, providing more aerodynamic stability

3. To ensure efficient cooling , Renault had larger cooling inlets (ducts)

[bar555]

REAR BRAKES - TURKEY


1. Discs with radial grooves that increase the bite rate between disk and pads, hence increasing the average temperature of the brakes

2.Brake ducts

3.Brake callipers
