Lowering springs and Cobra R's

[Coupe Devil]

I found a set of use Eibach's for 75 bucks and a guy that wants to trade a set of cobra R's wiht new tires for a set of pony's. I have a set of ponys I would trade and and also like to lower the car. Will this work. And do I have to swap shocks and struts?
