Question How to adjust Tein Flex for softest ride?

I recently had a set of Tein Flex installed in my '03 sedan. The ride is feels very stiff even at the softest dampening level. I raised the ride height to about 13.5" all around and it seems no better. Is it possible to get the Flex to ride even remotely close to stock comfort levels?

Can someone please enlighten me on the proper way to adjust these Flex's for optimum comfort? The instruction manual is not very clear in raising/lowering ride height. In looking at the diagram in the manual there is a "seat lock" for the spring itself and also a "bracket lock below" that. Do I loosen the bracket lock then turn the shock body to shorten/lengthen the shock body? And what is this pre-load I've read about?

I bought these Teins based on my experience with them in my Miata. I love them on the Miata. The dampening range seems to be much greater on the Miata then it is on the WRX.

Thanks for all comments!

with the flex's you can go +/- 2k on the springs, so i would start with buying a set (4) of 4k springs (223#/in), and swapping those for the 5k's (280#/in) that you have currently.

or, alternatively, you could go all the way down to 3k's (168#/in).

IIRC, tein charges $50/pair of springs - that's a REALLY good price (eibach's ERS springs are $100/pair).

Default It's real simple.

First, if you have the EDFC, you need to disconnect the end wiring that goes to the motor to prevent it from "wrapping" around the top of the shaft. Now you turn the shock body to adjust ride height, which has nothing to do with the stiffness. Unlock the two rings that are threaded with the supplied "hooks" and then spin the top one clockwise (down) to soften the spring setting. Bear in mind when you lower the rings to soften it up, you have to compensate for the ride height. Lock the rings and go for a ride (put the wheels back on first). Adjust as necessary.
