Update
Its middle of winter here.
I trimmed down the lower side sections of the front airdam because it was scraping on the driveway. Then i also trimed the upper end corners so it would reduce frontal area and better deflect air around the front wheels.
I have also made side skirts. I placed them on the seam under the sills for simplicity.I Have also made rear wheels splats to aid in air flow around the rear tyres.
