The softer option tyres are faster because they are stickier, they literally stick to the track at optimum temperature hence providing more grip, which in turn helps the driver to go faster. They are much less durable than the harder compound. ... Drivers must use both set of compounds during a race.

Race trim is wear the driver will go out and do a stint they would usually do in a race. Race trim is normally to give the team an idea on what the best strategy is going to be. Where qualifying trim is where the driver would push flat out on the fastest compound of tire available at the weekend.

DBA rotors are great. Used them (old slotted design, replaced now by the T2 model?) in track cars doing a collective 1000-1800 laps a day. No issues other then warping if the car has been sitting too long after coming in hot. This would happen on any rotor.

The equal length header is a much more efficient design for a couple of reasons, but it all stems from the exhaust runners being the same length. ... This comes also with a normalization of exhaust pressure (backpressure) at each exhaust port which improves engine volumetric efficiency and top-end power.

It's not likely to happen soon. Even if they were more fuel efficient, they wouldn't make a comeback in their original form. The steam locomotives required way more maintenance than the diesel locomotives, and way more manpower to keep them operating and repaired which is why they were replaced by diesel locomotives.
