The FIA have launched to-date, or will launch in the next 30 days, invitations to tender for supplies of standard of Formula 1 components from 2021 as it continues to pursue ways of reducing costs for the teams.

1. Gearbox
2. Wheel Rims
3. Brake friction material
4. Brake system (brake-by-wire, calipers and master cylinder)

But why stop there? Why not wings, steering wheels, dampers, ECU, fuel bladder, and more?

"The gearbox was the first one to be launched, it was launched in February," FIA head of single-seater technical matters Nikolas Tombazis told Motorsport. "We got the bids in and we're now into the phase of making a report to the World Motor Sport Council.

"The other three the deadline is [coming up] and the bids haven't come through yet, so we'll see what happens.

"There will be a few more launched over the next few weeks and months on smaller components. We have been discussing it a lot with the teams over the last few months, and we will be presenting a lot of stuff to the teams in June, so it's quite soon.

"Teams will know well ahead of 2021 what it is they need to make, what it is they need to buy. So they will be able to make their plans I feel quite accurately, with full information."

"The ones that we're going to launch in the coming week are items which we're going to have finalized by the end of June, and they are the sort of things which teams will definitely have enough time to react to, whatever it is.

"Then the tenders that will be launched a bit further down the line are maybe standard sensors in certain cases, and stuff like that, which really are not that major.

"I have to stress that sometimes a standard supply of certain things may have an added potential benefit, which may be policing.

"There are already some standard sensors on the car for policing for example fuel flow, so sometimes we select standard supply if it's a performance critical sensor which we need to monitor for legality. That can be an added reason, apart from costs."

"In the rules there will be provision for certain things to be standard supply, there will also be exact provisions for what happens if that standard supply does not succeed, what happens then for these pieces, how do we achieve cost reduction if the standard supply fails.

"That could happen either because nobody wins the tender, or to could happen because somebody supplies something and then for whatever reason pulls out after two years and we're faced with that situation."
