However, as tomorrows forecast is dry, how the hell do the teams manage changing today's wet setup on full wets to tomorrow's need for a full dry setup on slicks, what are the rules about what they can do to the cars now I guess in park ferme and their choice of tyres for the race?
Ah! The old wet set-up conundrum….
It has been a long-held belief that there is a huge difference between a wet and dry set-up.
After many years in sportscars where when we would often run through various weather conditions, and a couple of years running a whole grid of identical cars with the ability to change almost everything for the wet conditions, I came to the conclusions that changes for the wet should be restricted to:
- Fit wet tyres
- Adjust brake balance to the rear (You can’t get as much weight transfer in the wet)
- Switch on rain light.
All the rest is purely discretionary in my considered opinion and over 40 years practical experience.
Yes, of course you can change springs, bars, damper, aero and lots of other parameters to get a car that will give more ‘feel’ to the driver and may theoretically be better over a single wet lap, but at the end of the day, it comes down to the driver. Those who can input and process the sum of all their senses and output it as car control will be quicker.
I’ve seen drivers set wet pole positions with a stock dry set-up and others with ‘optimised’ soft wet set-ups.
With current F1 parc ferme regulations I understand that the physical changes are limited to front wing adjustments, and that the wet tyres will raise the ride heights by being slightly larger diameter. The driver then has control of the brake balance, diff settings and rain light.
