Blazin Si

I want make my car a little less bouncy and was looking at the Koni Yellow's since they have an adjustable perch. This would let me even out my ride height without changing springs.

I wanted to know if anyone has done this with a modified top hat to avoid bottoming out. It doesn't seem like the S-Tech's have a high enough spring rate for the lower spring perch setting. It looks like it works with other Honda models, I'd just like to know if anyone has done this with a CL.
