Koni Coilovers vs KYB shocks/struts trade

[chixwithtrix]

A friend of mine just bought a S13 equipped with Koni coilovers/Eibach springs and really has no use for them. I was thinking about trading him my KYB adjustable shocks/springs for his Konis since my S13 is a drift only car and needs a more adjustable suspension.

What are your thoughts on the trade, would it be worth the hassle? How do Koni coilovers/Eibach springs perform?

Also, I have searched around for the part numbers (1081 sports) on the coilovers and came up with shocks, not coilovers...? These are indeed coilovers correct?
