IIRC, there's a member here that has the factory GT4 vents on their Evora, but it required removal of the rear upper and lower clam for install and paint matching.I wonder if anybody has ever considered installing a pair of these on an Evora..... I mean obviously one would have to have a pretty aggressive, track focused type build. They would be perfect for adding some cooling ducts to the rear brakes while also filling that huge, boring, plain open void area in front of the rear wheels.
If memory serves, most variants of the Evora GT4 over the years have used this exact same dual NACA duct design for rear brakes cooling, only it's always integrated into the painted side/rocker panel.
EDIT: Found it. @Vancouver has them: Evora S vs Evora 400..Picture Battle?
