Ride height is critical for an #F1 car, adjustment may be only a by a millimetre. But, how do they adjust it?
Its most commonly done with the push (pull) rod length. By changing shims in the rod.
Thicker shims raise a pushrod ride height. The opposite for pullrod.
#F1 #TechTalk
The carbon rod and (typically) metal end are bolted together. Creating space for a shim.
Teams have a lookup table, relating a ride height change to a specific thickness of shim.
There's a box of different sized shims in the garage, matched to the list.
#F1 #TechTalk
With the car on its stands in the garage, the bolt can be loosened, to open up the joint, allowing the shim to be removed and new one added.
It's a bit trickier with pull rod as the gap is pressed closed by the weight of the suspension assembly.

This shows an old Jordan pushrod. With similar detail to the Caterham mock up pushrod above.

2026 #F1 power unit regs are out. Summary, the same layout and power output (~1000hp).
But new; eFuel, less fuel flow, and greater ERS-K, to compensate for the loss of combustion power, the ERS-H & Variable trumpets.

#TechTalk
This means we keep the power, but more will come from the hybrid system, not quite 50/50.
#F1 #TechTalk
Without the MGUH and variable trumpets the combustion engine will be more laggy. With the reduced fuel flow exhaust-flaming hot antilag strategies won't be practical. Cold antilag and using the added output from the MGUK will be required.

One of the most interesting cars, #BritishGP spec deep dives
@redbullracing #RB16
#F1 #TechTalk
@BremboBrakes bespoke machined with metal bridges to add stiffness . Heated flow out of the brakes ducted back through the scoop outlet.
#F1 #TechTalk
Floor fences and edge, still the most complex in shape and detail. Outwash over the floor edge strongly influenced by side pod undercut.

Repackaged coolers in the sidepods and above the engine were a key part of the Silverstone upgrade.

Continuing the @ScarbsTech #BritishGP spec deep dives...
@McLarenF1 Mercedes MCL36
#F1 #TechTalk
Mcl went with a complex floor edge far earlier than most. With a finned scrolled edge towards the front, a flap in the mid section and a well supported deck in front of the rear tyre.
#F1 #TechTalk
Speed Kiwi on the DRS pod. The lower DRS linkage pulls the flap open, the upper part omission a stay with a pivoted end to support the wide flap.

#BritishGP spec deep dive:
#F1 #TechTalk
The updated floor, in particular the floor edge, with a wavy edged flap, mid flap and a simpler treatment ahead of the rear wheel
#F1 #TechTalk
Another team to copy the Aston Martin bib wing. Curved floor fences, note the change in height of the tunnel roof inbetween them.
