Rake pics? Rim opinions?

[79gmcclassic]

In this pic you'll see how my truck sits level with flip kit and 2 inch aprons and 2.5 inch spindles up front... Well I want some rake but also want new wheels debating between some nice 17s or slots or a nice 15 inch wheel! I have 255/60/15 all way around right now on 15x8. But I want some rake and the trac width to be even all the way around on the outer edge of the tires(staggered rears) but just wondering if you guys would know my best options?! Please present pictures of rake and specs if possible!thanks guys!!!
