Ribbed rear wheel rims

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.
