suspension for disco td5 2"-3" lift

Hello,

A friend just gave me a new Eibach very good springs (set of 4),
The front spring is 430mm and the rear is 470mm so I need to buy a new suspension kit (great gift).
I can get Koni shocks at a good price.
Does anyone have a good experience with them?
What model will fit a 3" lift for the disco 2?

Thanks
