- mm is inward movement
+mm is outward movement

+40mm 0,4961
+30mm 0,4870
+20mm 0,4908
+10mm 0,4896
STD 0,490
-10mm 0,4926
-20mm 0,4900
-30mm 0,4829
-40mm 0,4835

Next I will put convex hubcab there which will come outwards +20mm at the center. And for next runs I will also take down the actual forces as the frontal area changes little bit so the drag coefficient calculations are not exact. Frontal area grows from A=1,0218m2 to A convex capsels=1,0226m2

My guess for sweet spot is between -20 to -30mm range. Specially when wheels are rotating
After that I will try to put it then rotating. Pics will follow later

any thoughts on the hyundai ioniq blues hubcaps?
