Yep...OTS Koni sports adjust rebound only. If the KYBs adjust like Tokico Illuminas, and I am pretty sure they do, the adjustment moves bump and rebound simultaneously...may or may not be a good thing--but can get skittish at full hard. Even if it is bump only, as stated above...the skittishness is the possible result. Konis can be made into double-adjustable, and bump and rebound can be moved independent of each other. Also, Konis can be revalved to accept very high spring rates...and shortened for lower than OE ride heights. They work OK up to around 550-660 in/lb in the OTS configuration--well under H&R Race rates.
Here is a link discussing various dampers for Miatas...should hold consistant for Foci as well: http://www.fatcatmotorsports.com/FCM_app_guide.htm
