None really. It's two different things.
What you could do is look for a skydiving container big enough to hold a BASE canopy, so you can jump your BASE canopy out of a plane to practice with it. You'll want a skydiving canopy for most of your jump, because they open nicer at terminal than a BASE canopy, but you can get a big 7-cell for skydiving and wingsuiting.
You'll need a BASE rig as well. I'm guessing you'll want to stack up some BASE jumps before you hit Norway, so look into one of those, and maybe take a BASE course in Twin Falls.
It's a 'lofty' goal to wingsuit off a cliff. If you plan to proximity fly the cliff, it's even more of a project. Fugre you'll need a couple hundred skydives to start with a wingsuit, and a couple hundred BASE jumps to take a wingsuit off a cliff, and then a couple hundred wingsuit BASE jumps before you start hugging the wall. The skydives and regular BASE jumps you can make in the US (if you don't mind breaking a few laws along the way, BASE jumping requires some tresspassing and maybe some light breaking and entering). The big wall jumps can only be made in Norway/Europe, so you'll need to find a way to spend some time over there to get your skills together.
First order of business, get current and look into the BASE first jump course.
Yea it's not an over night sensation. I live fairly close to the new river and BRIDGE DAY so that will be my training grounds... Trust me I've done a little research and know how many bare minimum jumps are required to BASE both here in the states and Norwway... Thanks to all for your responses. I read a bunch of pretty positive remarks about my local DZ in Chambersburg, PA so I'm stoked about hooking up and getting back into the...
