With stock length struts and 8 inch springs you can easily get it higher that stock height. With 10 inch springs the sky is the limit. Just look for coilovers with full length struts.
Sorry to turn this into a sales pitch but I have a set of AGXs with properly mounted GC sleeves available that would be wonderful with the 10 inch springs. PM me if you want to discuss them or want pics.
There are also rally coilovers built by HotBits. You can find a number of people who sell them on specialstage.com.
I've got them and they are pretty good. Looking at about $1500 I think. DMS will run you close to $4500, Reiger or RS&SP are available for a little bit more.
