Do you run with the front arch liners removed?

Do some research on wheel well pressure areas. Pressure tends to build up at the top of the wheel well and cause front end lift. This is why the boxster rads are vented out the side instead of directly back into the wheels. You may wish to consider maintaining this, or at least vent the top of your fenders and turn that lift into down force.

Good info, thank you...

Actually the radiators vent down on both the 996 and the 986. Cup cars vent differently.

Anyway leave the liners and ditch the fans.
