may I ask the reason as to why many porsche drivers like to operate the aerodynamic spoiler at speed interval not set in the electronic map?

Just a note, I would suggest using Mobil one's latest generation coolant, its chemistry is advcanced in both anti corrosion and thermal transfer properties. There are also other common sense advantages
Adjusting rear wing of MK1
in 996 GT3
Posted
Dear All,
I have not had chance to read all the replies on this topic, but just wanted to add,
We carried out many external analyses both using CFD and wind tunnel techniques to fine tune the exact characteristics of the GT3 rear wing. The design is specifically modelled to interact perfectly with the vehicle body.
Indeed adjusting the rear wing will improve the -ve lift, and as mentioned will encourage the front end to yaw, but by reducing the front suspension so the car sit at a slightly different angle is counter acting your adjustments to the rear wing.
You best bet to help this yawing effect is to look in to an alternative bumper design, that forces the air to flow around the car and not under it, just as a splitter does. To improve it further, you could look at deeper side sill, but try not to ruin the aesthetic pleasure of the vehicle. These additions help to produce a vacuum under the car, as first achieved by Lotus Race Engineering back in the 70's.
Hope this helps
