Also this

"Install Airtabs 3 per foot which is one every 4 inches on center. Airtabs are 4.76” long, 3.25” wide, and 1” high. Metric: 12cm long, 8.2cm wide, 2.5cm high. Spacing is 10.1 cm on center. Increase spacing to avoid rivet heads, lights, grab bars etc. Do NOT decrease spacing as this may decrease performance."

I rechecked and I need to put back a few...

I had so call expert tell me I had too many...and I removed every other one on the sides.

BUT I had been running them for a couple of years and with so small a improvement calmed could never tell if they or my extra ground effect add ons did ANY good.

I was hoping they would help the van...
