A selection of the best Formula 1 technical images from the Belgian Grand Prix weekend courtesy of Giorgio Piola.
Ferrari SF70H, brake disc
This image of the brake disc outside of the car offers a look at Ferrari’s blown axle solution, with the carbon fibre nozzle shaped differently to the cylindrical axle it fits within.
Ferrari SF70H, detail front wing
Ferrari has made a change to its front wing in Belgium, removing the triangular fin from the upper edge of the endplate (arrowed).
Renault Sport F1 Team RS17, front wing
On Renault's front wing, note the cutout toward the outer section of the upper flap.
Sauber C36, engine cover
Sauber has brought its revised engine cover design to Belgium, having trialled it the post-race test in Hungary. The team had favoured a shark fin-style cover in the preceding races, with various iterations of the T-wing utilised throughout. The new cover is sculpted like the covers we’d ordinarily expect to see, pre-2017, with a vertical tail used to house the T-wing.

Red Bull Racing RB13, rear
Red Bull has brought a lower-downforce rear wing assembly to Spa, in an effort to offset its power unit deficit against the likes of Ferrari and Mercedes.
Williams FW40, rear suspension
Williams tested a new suspension for the FW40 in Hungary, which appears to have been given the green light for the race in Belgium. The layout should have both aerodynamic and kinematic advantages, as the connection point to the upright has been changed (arrow).

The old specification of the Williams FW40 suspension, with no T-wing fitted.
McLaren MCL32, rear wing
McLaren has a new rear wing for Spa, which features a gentle spoon shaping, with a shorter chord used at the mainplane and upper flaps' extremities. The broader, shallower monkey seat introduced in Hungary is retained.
Mercedes-Benz F1 W08, gearbox
A look at the gearbox, crash structure, suspension and rear brakes of the W08 as it awaits installation.
Ferrari SF70H, sidepods
The area ahead of the rear tyre has become one of particular focus for Ferrari, with numerous changes made in the preceding GPs as the team looks to maximise its aerodynamic efficiency. The Belgian GP is no different, with the seven L-shaped slots Ferrari had used in Hungary reduced once more to six, so as to create the right airflow structures for the given speed threshold. Added to the edge of the floor is a feature we’ve seen used by Mercedes already this season (arrowed), where a small arched scroll sits poised to alter the airflow's direction.
