Ditch the fans. Leave the liners in place unless you plan to buy the two piece GT3 liners which BLOCK off the bottom air exit and direct it in next to the body.
We took a new to the track car out this past weekend.. it beat the backside of the radiators up in NO time (with no inner fenderwell liners) ... on Nitto NT01's!!! (would have been much worse with a slick)
Do not worry about grid. NO PORSCHE CUP CAR OR RSR shipped with fans
The second you start moving the temps will drop drastically (even moving through the pits)
Last time I checked
You don't get 100 degree+ days in Finland very often
