There was a point where I thought it might be interesting to install a few of these so called air tabs on the rear of the van. I was under the impression that these would help with cross winds while on the highway. The van being light, is hit by some heavy cross winds which makes the van unstable. Often I fear that I'd be pulled over by the police or highway patrol thinking I was driving drunk.
Searching into these air tabs, I found this to be more than I was willing to pay and once mounted on the van, would look down right silly even ugly. mind you I had downloaded a free wishbone design off a creative commons 3d printing site and had the shop print 40 of these things.
With a change of mind, I'm still searching for something that's less likely to draw attention but could still have the benefits of gaining some cross wind deflections. My thought, would a 3 point star pattern, being more flush design offer the same benefits as the wishbone design of the air tabs.
As a last resort and highly unlikely we would do this either.. but I have seen the stick on jet plane type things on some tuner cars.. or maybe those smooth strips with nubs as seen on the roof of some tuner cars..
UPDATE:
I just had a brain storm and sent a few emails to companies I though could handle making something like this.. topic will be updated as soon as we get some sort of reply. Could this be a new wave for the future of race cars by adding my device? we'll see.
