If the price tag of the Tein Flex doesn't scare you of, then you can't go wrong with them. There are several good options that are cheaper, but none of them stack up to the Teins IMHO. If I had the cash at the time, I would have gone with the Teins. Instead, I am running Flyin Miata Springs with KYB AGX shocks... A nice combo for the price but I still toy with the idea of swapping them out for the Teins.
