Acura EL 1999 picture as out of storage in May 2020

This is a profile view of the car just out of storage before a "dust test". The car is showing the front spoiler that acts as an air dam for the front wheels; unseen is the belly pan, front part from spoiler to wheel shafts and direction links in aluminium, middle part in choroplast, rear part is a 6 degrees diffuser also in chloroplast. The car is also equipped with vertical deflectors in front of the rear wheels and OEM side skirts are extended down by 2 1/2 inches with painted vinyl gutter split in halves (see picture, costed 5 $ at hardware store).

The front spoiler is only 120 mm (about 5 inches) above ground. The middle part of the car is about 150 mm (6 inches) and as flat as possible: the exhaust from headers to rear is not covered. From the rear suspension links, a "diffuser" sweeps up by 6 degrees attached at the front with "zipties" and affixed to the rear plastic bumper cover with self taping screws : no more brake parachute effect from the rear bumper cover! Total height from ground under the rear bumper cover is 30 cm (12 inches). I guess the car "rake" and the "venturi effect" are improved.
