If that price seems too high, you probably don't need an "FD spec" cage, because the entry fee for your first FD event is almost the same price! haha :( :(
I have JDM ones. They are JDM. They're made in JAPAN. They have anime airbrushed on them. They are specifically valved for mountain TOUGE and WANGAN highway runs. I had them shipped from JAPAN because they are not available in the US.
