Tein monosport or Flex A?
 

I'd love to hear some opinions from those that have used either. I'm interested in Tein because eventually I would like to try EDFC. This is not a daily driver, but I don't want something that bounces all over the place on every bump.

My basic requirements are lower (at least ~1.5"), ability to adjust the ride when I just want to be comfortable, and ability to hit the track on club days just for fun (so better performing than stock would be nice).

Is the $600 upgrade for the monosport worth it in my particular case?

Both, with proper damping settings/alignment/ride height will handle noticably better than stock. The Flex line is more of a street oriented coilover that can do track, the monosport is a track oriented coilover that can do street. If you look at the spring rates, the monosport is much stiffer so it will be a rougher ride, and the damping characteristics will also be firmer. It depends on your roads and what you're looking for - sounds like the Flex's would be fine and more what you're looking for if it's a DD that needs ride compliance with potential for the occasional track day.

I daily drive the Monosport's on the shit-tacular roads we have up here.

Yes, it can be a little bumpy and there is some more NVH because of the pillowball mounts (and the other stuff I have) but meh, it's a sports car.

I went for the Monosports because I track my car reasonably regularly.

Thanks for both of your input! I decided to try out the flex A with the idea that I want to try active pro EDFC (really the only reason I'm going with Tein). I think for my needs it may end up making me the happiest, but I guess I'll see.

I'm dizzy with the number of options on the FR-S and the number of suspension opinions.
@jvincent how do you feel about your monosport on the track? If you dial the monosport damping down, would you say it's still harsher than stock?

EDFC Active Pro is ridiculously good after you have it tuned.

The car definitely feels more stable in the high speed corners, which is where I was starting to feel a little loose on the OEM suspension. I'm not terribly fast at the track compared to others, but my desire to keep the car on the track meant it was time for an upgrade.

To be honest I've never tried setting it to a soft setting at the track. Maybe I'll do that for the drive home tonight just to see how it feels.
