finished my prototype upper grill block, coroplast is hard to get on a sunday, thank you local elections.
I just sprayed it black, will get some black coroplast soon and re-do the upper section in one piece
Next up:
1.fix factory lower air dam (tweaked by driveway)
2.smooth transition over from front fog light openings
3.partial lower grill block, install walls behind bumper to direct air
4.re-engineer air dams forward of the wheels
5.more to come...
