I could have sworn they are out in Japan... ( I know doesn't quite help us) I think I saw a link in one of the JDM Tunershops for them. I haven't heard anything about TEIN USA bringing them out soon. I very much enjoy my TEIN Flex's, though I am going to be upgrading the spring rates next year.
I brought home a set from vacation in Tokyo this summer
But not installed yet - so no 'user review' - sorry. Have to maintain my stock class set-up a little longer.
I saw a Tein-usa ad recently in Sport Compact magazine, that said they were available as special order?
