Ok Clarify the Rules Please

[Roamy]

So just what can you change on a F1 car before the race. Meaning after qualifying. A wet set up is quite different that a dry one. So if a car qualifies with a dry set up and it rains for the race can they change the car??

34) POST QUALIFYING PARC FERME
34.1 Each car will be deemed to be in parc ferme from the time at which it leaves the pit lane for the first time during qualifying practice until the start of the race. Any car which fails to leave the pit lane during qualifying practice will be deemed to be in parc ferme at the end of Q1.
Between these times, other than when cars are returned to the parc ferme overnight, the following work may be carried out :
- engines may be started ;
- fuel may be added or removed and a fuel breather fitted ;
- wheels and tyres may be removed, changed or rebalanced and tyre pressures checked ;
- spark plugs may be removed in order to carry out an internal engine inspection and cylinder compression checks ;
- permitted heating or cooling devices may be fitted ;
- a jump battery may be connected and on board electrical units may be freely accessed via a physical connection to the car ;
- charging and / or discharging of the KERS energy storage devices ;
- removal of the KERS energy storage devices which, once marked by the FIA technical delegate, may be retained overnight by the team ;
- the main electrical battery and radio batteries may be changed ;
- the brake system may be bled ;
- engine oil may be drained ;
- compressed gases may be drained or added ;
- fluids with a specific gravity less than 1.1 may be drained and/or replenished, however, fluids used for replenishment must conform to the same specification as the original fluid ;
- the aerodynamic set up of the front wing may be adjusted using the existing parts. No parts may be added, removed or replaced ;
- if the FIA technical delegate is satisfied that changes in climatic conditions necessitate alterations to the specification of a car, changes may be made to the air ducts around the front and rear brakes and radiator ducts. These changes may be made at any time after the message “CHANGE IN CLIMATIC CONDITIONS” is shown on the timing monitors, from this point the choice of brake cooling and radiator ducts is free, subject always to compliance with the relevant Technical Regulations.
- bodywork (excluding radiators) may be removed and / or cleaned ;
- cosmetic changes may be made to the bodywork and tape may be added ;
- any part of the car may be cleaned ;
- on board cameras, marshalling system components, timing transponders and any associated equipment may be removed, refitted or checked ;

Yes, but not a lot.

Otherwise:
Suspension (but you'll start from the pit lane)
Front wing
Tyres
...and not much else.

I think you are allowed to wipe the windshield.

Must be lint free cloth that is used, otherwise a stop-go will be imposed.

Do you think that In the situation of a hot dry qualy and cold wet race... changing the suspension to a softer setting would ever be worth starting from the pit lane for the race?

Never, unless they were already at or near the back.

No one can confidently say it will rain enough during a race to make that sacrifice worthwhile.

However, there have been a few Saturday gambles on a wet-oriented setup for the race. But they don't often work.
