I don't know if Rays did anything different on these wheels. Our GX is our foul weather vehicle and most likely won't see any rugged off-roading.
Which one is your GX?
Honestly, I just got the wheels on yesterday afternoon. My wife is driving it around today. The wheels were just made because they weren't in inventory. It may be a new casting. I'll have to check.
After an 8 month wait I finally have my Rays Gram Lights Trans X on.
The funny thing is I likely crossed paths with the wheels on a recent trip to Japan, traveling from Osaka to Sannomiya, Kobe.
