Do JDM Rain Guards / Side Visors Actually Work?, Or are they just for looks? Options

[JoshuaM]

Yup, you heard me I have been thinking about adding JDM side rain deflectors to my project plan, and was just wondering if anybody who had them could actually comment on their effectiveness, since they are so tiny!

You obviously wouldn't go driving around with your windows wide open in the rain, but it annoys me that I need to leave my windows rolled up for several kilometers after washing my windscreen or if there was any water sitting on the car from the night before as with the highly raked shape of the Celicas it just falls right in!

I may end up with them eventually even if they are just for show, but if I am able to convince myself that they are a practical addition to my car then they might move up the priority list

Thank you,
Joshua

The side rain visor actually works quite well for me.
I live in the climate where I have to use my washer fluid quite often and when doing so, it washes the grime and throws it to the edge of the A-pillar. While driving without the side rain visor, the fluid would follow the lip between the wind shield and the A-pillar up and around to my side windows. This leave unsightly streaks on my window and I don't appreciate it. After installing the side rain visor the fluid wouldn't run on to the side window which does exactly what I need it to do.

So from my experience and expectation, it's a good investment.
