Look like you guys are on the right track. I've installed the 2.5/1.5 and also the budget boost, install is the same (unless you get the 2.5/1.5 kit from Wheeler's that still used the preload spacer). 2.5/1.5 or Budgest boost front/1.5 rear would be the same difficulty to install, I can't say one is better than the other. It's purely up the the individual and how much rake they want left. When I did the 2.5/1.5, the results were very close to 2.5/1.5.

With the design of these kits, the install is very easy. The only problem is that for you guys up north, rust can be a real issue. I'd read through the write-ups and find every bolt you'll need to touch, then start soaking it in penetrating oil (WD-40 or similar) every day for at least a week. Any shop that does suspension or lift installs can do it. If they are not familiar with XREAS, just be sure they don't disconnect the lines and it'll be fine. It's not a hard install if you decide to do it yourself.
