It's not eco related, except in small tyre weight offset but the 0-60 today was 6.8 so the 7.2 would be a good estimate for 55 profile tyres. The battery was about 80-90%

Anyway added some photos, I decided to split the air to the lower dam so openings will be made in the bumper, from the nose down looking from above the air goes to the sides and there will be a modest splitter. The bumper edges just giving the car overall shape.

With the rear, it will have the large diffuser same as the white car but yellow areas show the floor extending to the rear. The venturi is just fake, contemporary

I have reopened the upper cooling slot so air is pulled through and down maybe 1.5 inch by 15 or something

One more thing, decided on 195/50. I use the tools online below, they are good
