I have for sale a set of used (but very good condition) Tein Control Master Type Flex (Part No. D6N64-11931) for the Nissan Skyline R33 GTS-t (ECR33).
The Tein Control Master Type Flex are height adjustable and damping adjustable up to 16-levels. These are also EDFC compatible if you wish to purchase the modules separately.
Interested? Shoot me an e-mail via eujin[at]hotmail[dot]com.
