I found this:
For less than US$8.50 (JPY 830), this was too good not to try.
So while June is rainy season in Japan, on a sunny day I broke out the can of KR4 spray paint (which I still have left over from the fluidic nozzle mod) and spray painted the two pieces for the mirror in the hopes that they would blend in fairly decently.
Then on a trip to Chiba prefecture just today (to implement Step 1 of my long awaited audio upgrade... stay tuned, pun intended) I had the opportunity to try these pieces out. Mounting was as simple of finding a place to put them, peeling off the double stick tape, and sticking them on:
|On the B Pillar|
|This was the only place this piece would stick on the door sail|
|You can see the knob sticking out off the bottom of the mirror|
And then it was a matter of driving to see what the difference was.
Uh... well... I could NOT tell the difference - not because these don't work - maybe they do - but because the road noise and engine noise coming in from the firewall area, plus the sound of the exhaust, basically made it too loud for me to hear any wind noise. For my audio upgrade, while I did lay down sound deadening as well as undercoating looks like I will have to do the firewall...
I even drove (a bit ?? lol) over the speed limit, in the hopes that at really fast speed wind noise would be more apparent - but no difference. The only thing I DID notice, however, was that my BNR34 rear diffuser was working quite nicely - sending up a rooster tail of water at speed (it was raining quite hard by the time I was driving back home today).
Thankfully, again this aero mod cost me less than 850 yen to try.... maybe I can find a Prius to try it out on...
