An option is to get the B14 then revalve them to stock spec, or slightly fermer to offset the height difference. The progressive rates are the best for comfort. Not nessecarily the best for performance though.

I have driven tuned / lowered cars for almost 20 years, but this one is the roughest between 70-80 mph, which is where I live on the highway.

I feel the same way about my iSports. There is no high speed dampening. I feel like the car is going to launch itself off the road when I hit bumps at highway speeds. Rather disappointed in them honestly....

I set mine to the settings in boldface below from @Moto-P

Out of the box the coils are usually set to 50% from full soft/hard on both the fronts and rears (even the ones that are supposed to be set to "Moto-spec"). Both mine and my buddies @WRB5titch came this way.

As for specific setup in motorsport use, the settings will vary on the tires being used (including the sizes, compound, pressures, and adhesion levels for the venue and conditions), and ride height set, as well as your driving preference. For general setup, you can start with 50% damping on your shocks, and in most cases it is somewhere near this unless you are using super high grip R compound tires, or negotiating a particularly fast raceway where you want stability more than agility, in which case you can opt to over-damp the springs by going higher...

Remember to turn all the way up clockwise till it stops, then click your way back each time you make an adjustment. It is good for the screw mechanism of the valve as well as click-stop bearings to rotate it, and a good habit so you are absolutely sure you have the right setting and starting point of measurement is consistent. For the FRS unit, 36 clicks back front is full soft, and for the rear 24 clicks back to full soft.

Lol... I was the one that asked the same question in that thread. And that's how mine are set up.... And I still feel they are lacking. Oh well. I'll buy better next time I guess.

You're actually the first person I've ever heard this from. For $1700 and the level of performance the Sports-i's provide I don't know if there's anything that touches their road comfort/performance/cost mix.

I think you might actually have preferred something sprung softer like STs which are sprung at 5k front /6k rear IIRC.

how low are you? are you sure you are not experiencing bump steer?

[wootwoot]

20mm lower. -2.3 front -1.5 rear. Corner balanced.

What are your toe settings front and back?

Any other suspension mods? Bushings, etc.? Tires size, tire pressure?

Have you considered getting the dampers properly adjusted by a professional?

0 front, 1/16 in on the rear.

Stock wheels and tires. Poly bushings in control arms. RacerX rear control arms and Whiteline toe arms. Subaru crash bolts. A few other things...

No idea where to go for that. I suppose you would offer that service to me but you are on the other side of the state. Corner balance and alignment were done professionally. PM me what, if anything, you can do.

That's about perfect for DD. I don't know what to tell you in regards to the back end getting loose on fast corners. Mine feels practically glued, even on So Cal's horrible highways. Last question would be what tires are you running? Like @CSG_Mike suggested, I would definitely take it to a pro that is familiar with your coils. If it's not setup properly than the only thing I can think of is that there is a chance that you got something defective.
