Hello *****
Thank you for your inquiry and your continued support of Tanabe performance products!
You do in fact have authentic Tanabe springs. We have went through several color changes over the years as we have improved the coating processes.
NF210 was available in these colors (from earliest to newest):
Dark Blue/Purple (Paint Coating)
Light Blue (Powder Coating)
Red (Double Powder Coating)
DF210 was available in these colors (from earliest to newest):
Light Metallic Purple (Paint Coating)
White (Powder Coating)
Red (Double Powder Coating)
The boxes have remained the same with the original color, but have a sticker label in Japanese explaining the color difference. Our newer springs will be shipped with newer boxes in the future.
If you have any additional questions, please feel free to contact us anytime!
Best Regards,
Tanabe Racing Development, USA
