Sadly, the link doesn't work.... connection refused.
I even tried googling to get the same results...no dice.
In the end, my recommendation is to start with the manufacturer's site and from there, find a vendor that is an authorised retailer. That's how I bought mine, and the experience I had was fantastic.
From the TEIN USA site... I found Fine Line Imports in Santa Rosa ... a great little shop who handled the install of my TEIN SS coilovers. While they spun the wrenches, I was in a cafè, writing and thus earning money. FLI, despite its small size, is the pinnacle of professionalism and I heartily recommend them.
