Unfortunately I have to install stoneguards on my RX7..I live a couple miles down a gravel lane and even at 10mph I spit up quite a bit. My rocker panels are starting to get fairly roughed up..
Any way- the guards I picked up are supposedly fit for a 1st gen and are molded ABS. They are black but paintable. I am debating whether to leave them black or paint them to my factory color.
Here is a pic of my car (a little grainy)..
I know i'm gonna catch hell from some folks, but the alternative is fugly too.

 

we'll its not like they don't serve a purpose. I'd leave them black, then if you don't like the way they look you can have them painted. Black should go well with the rims.
