When I bought my Z (which was used) it already had some mods done to it.. nismo wing, and springs, as far as I know. The dealership didn't know either. All I knew was that it was lowered how I wanted it, the ride was still ok, and the handling was good, so I wasn't concerned. But now that I'm looking at competing in BSP next year, I'm trying to figure out everything that's done to the car. And that brings me to my current question:

The other day when I was installing my exhaust, I got my first good look at my shocks and springs. Turns out I have tanabe GF210s (my friend recognized the logo, he has them on his subaru as well). I looked at my shocks, and they had some sort of silver sticker/label with a black logo that said "JR" on them. Sort of a back-to-back lettering thing... I didn't recognize it from anywhere. I'm guessing they are just factory OEM shocks, but I just wanted to make sure. Does anyone recognize that sticker/logo?
