Ribbed rear wheel rims in F1

So far I've only seen the ribbed rims on the launch McLaren presumably incorporating the similar Merc system of keeping the rear tyres cooler at race temperatures.It'll be interesting to see how many makes will sport this mod also taking in smaller wheel nut apperature as seen on the SF1000 for additional heat escape from brakes.

Yup. There is a disc and calliper nestling in that enclosure.

For those interested, here's a photo of the brakes without the shroud. They manage to pack a surprising amount of stuff in there.

And the other photo shows the ribs in the Mercedes wheel rim if anyone hasn't seen them before. Here's a good article from 2018 on the topic: https://www.autosport.com/f1/news/13...st-controversy

The wheels are made by well known wheel manufacturer and after reading the article I can't see the other teams ignoring this system if it's been passed by FIA as a 'non movable' aero mod to control core temp of the rear tyres.

Brake tech in F1 is really quite amazing, there's so much that could be discussed.

Talking about these fins and dissipating heat reminded me of the evolution of brake discs themselves. The number of holes used in break discs has increased from 100 to 1200! Worth looking into if you guys are interested.

Six rows on the pic on the right and now even thicker carbon discs maybe 9 rows or more even.Be interesting how they make them, and even more interesting how on earth do they drill 1200 holes and more.. I guess it's a computerised 6 or more drills multi chuck base staggered drilling in and out while the disc rotates a tiny amount each time then stops for the drilling.Add to that the brake-by-wire for the rear calipers to further complicate matters...

Agreed. Seeing the manufacturing process on these would be really cool. There used to be a "How It's Made" program here on TV (Can't remember who produced it, but older episodes are on YouTube). It would be really cool to see a similar type program with episodes on all the different F1 parts (hopefully with a bit more detail).

Maybe I'll go off and start my own YouTube channel to get started on this idea haha

This is not a thread-jack, just a short article on carbon ceramic brake disc failures on BMW's....the article states the carbon ceramic rotors are Brembo:

https://www.carsaddiction.com/articl...ceramic-brakes

BMW OEM carbon ceramic front discs: $7,200
https://www.turnermotorsport.com/p-2...6-f06-m6-pair/

BMW OEM carbon ceramic rear discs: $6,900
https://www.turnermotorsport.com/p-2...6-f06-m6-pair/

It's over $14,000 + just for the disc (rotor) replacements, plus carbon ceramic brake pads, brake fluid, plus labor, etc.

Thanks for putting it on Bruce,gives an insight to what problems can afflict that set up if your unlucky and apparently not lasting the life of vehicle. A bad batch can render them u/s after minimal mileage.
+ Another thing with them is care needed in removing wheel.The wheel needs to be very slightly above ground in removing to take off the hub upright as if edge catches the disc it could chip edge off rendering it unserviceable.
