Nothing wrong with Teins.
A friend of mine had them in his R32 GTR and was a nice comfortable ride and handled great. Mind you, his car was stock but with Tein's, so for a daily car at the time, it did the job and very well.
"Green was mentioned once in the article, "shiny green or purple shocks..." Probably referring to Tein (Green) and HKS (purple).
Gary, who..?
Meh... If the suspension engineer who you won't name, has done test to prove why they won't buy Japanese suspension bands, then naming them on here, won't hurt, what they got to lose, unless they can't back up what they claim / tested...
Post it, I will be interested in what they have to say.
Again, in that article you posted, yes I do agree, Bilstein, Koni and Ohlins are great, remember "I am pro Japanese when it comes to Skylines, with a few exceptions.".
Depending on the product, the few exceptions can be quite a lot...
