Comfortable ride, eliminated body roll, and much better handling over stock. They are capable of track duty as well.

I have the TEIN Flex A coilovers installed on my FRS and though they aren't harsh, the ride is more firm on the Flex A than on the Flex Z, which is why TEIN decided to incorporate the Hydraulic Bump Stop. They are valved with smoother roads in mind, like on a track. I love how the Flex A's drive, but IMO they are overkill if you plan to just do street driving.

As far as rear LCA's go, what's your budget and how low did you plan to drop the car? Feel free to shoot me a PM or email and we can discuss options!

Actually, the Flex A and Flex Z valving profile is almost identical. The difference is the Flex A is rebuildable, whereas the Flex Z is not. The Flex A has the HBS to prevent bottoming out under harsh conditions.
