I've been mulling over the springs too...
The BTG's are Front 1.75" Rear 1.50" - I noticed they billed them as retaining the original rake but I'd have to agree yours looks like it's dead even to me (rake wise).
The Eibach ProKit is the other I'm eyeing - Front 1.60" Rear 2.00" - If memory serves a couple of the folks here use these and have said it removes the rake completely.
I'd kinda like to keep the rake look which was why I was leaning toward the BTGs but after seeing those pics... now I'm stuck, lol. :/
Edit: So here's the promotional shot of the Eibach's before and after, is it just me or does it look like it's got more of the rake than GTSteve's above?
