When I called Stillen about their front tower strut brace, they said it wouldn't fit with my Tein EDFC adjustable suspension.
While the car was at VTR for a BBK upgrade, we tried one on and the fit was no problem. I was under the impression that the servos that adjust the dampers moved up through the openings in the middle of the mounting points, but they don't move up at all. Three days later I was enjoying a much crisper turn in through every one of Watkins Glen's 11 turns.
Why Stillen says it won't work is a mystery.

 

I have wanted to get one of the stillens for a while, but that is why i didn't get one - because they said it wouldn't fit with my EDFC. So you have one on now and it fits?

^ i has just as aprehensive as you, i did a lil research and supposedly it fits, well just installed them about 3 weeks ago and the do, theres no question that they won't fit,

Does the Stillen fit with the APS plenum?

 

^no, it will not clear.

Did you notice a difference in stability with the bar?

 

Yeah, did you notice a difference in stability?

 

i put it on the same time as the sways so i'm not sure how much alone it did but all together it makes a difference on the twisties
