You can order them through RHD Japan as well.. They have the Ti2000 listed on their website...
Price is $428.15 + $124.88 S/H
RS-R Ti2000 Suspension Set - Down Type Nissan Fairlady Z Z34
We could get them cheaper per set if we buy them as a group and order a bunch and then 1 person places the order and forwards the shipment to the different destinations... Just a thought..
