Chris_F: Not quite

http://www.tein.co.jp/productse.html

Tein Basics were made for the US for people who want a simple coilover to lower their car that isn't as dodgey as using lowered springs on standard shocks.They aren't really focussed on performance and they're not sold in Japan.

Tein Super Streets can use the EDFC for most vehicles, including the Euro. They use stronger rubber strut top mounts and are only height adjustable by raising/lowering the bottom spring perch. They have 16 stage adjustable dampers.

Tein Flex can also use the EDFC for most vehicles. They mainly use pillowball/rose-jointed/solid metal mounts for better steering feedback and less lateral suspension movement but with a slightly harsher ride as a result. They are height adjustable in two ways, by raising/lowering the bottom spring perch as well as raising/lowering the bottom shock mount. This will help to maintain better ride quality because you'll keep more shock travel.

Flex are DEFINITELY NOT the flagship!! Better to think of them as the best street oriented coilover from Tein, but there are many other models which are much more expensive and much better at their designated purpose than the Tein Flex. A good clue to look for when trying to work out if a coilover is top shelf or not are remote resorvoirs and separate adjustment for dampening and rebound like the Tein Type HG ... hmmmm ... sexy!!



I hope that helps.
