I've looked at the OEM spoiler/deflector thing that Honda sells, and it seems to have a big gap under it, like it's a wing on a racing car. I can't see it doing much for the cd. Plus, it costs about $200..
I've been looking at those top-edge spoilers this afternoon while bike riding.
I noticed that many of them curve downwards to follow the roof line.
The roof line on my CRV is sloping down towards the rear too. But, for some reason, I've been thinking that a lip(?) spoiler on top of that rear window should be level (parallel to the ground).
I was thinking of a thin 'Bill' like surface (shaped like a short bill of a baseball cap) on the back edge of the roof.
It would stick out in the center about 12" and curve back in on the ends.
Be like a little sun visor.
Sound crazy or what?
I won't get into building a boat-tail, but something that gives
some improvement while not looking to outlandish would be doable..
Thanks for any comments.
Cheers,
Rich
