LOL!! You need to talk to someone who's installed complex GenRight products. Send KenB1010 a PM and let him tell you just how keyed into anything they are. I should note that he IS a fan of GenRight but will tell it to you straight. If you're worried about precision, I would recommend that you give the EVO bolt-on kit a look as it's a no brainer and a lot cheaper.
With a few edits, I PM'ed this response to Jeeper52. I feel that it has relevance to the group... so here goes.

Hi, I took a few minutes to read through the thread. To give you some background. While I haven't run with their suspension kit, I looked closely at it prior to installing my Full Traction long arm kit. I have used GenRight’s Aux fuel tank and their rear tire carrier on my 07 jeep. I'll probably also run these same GenRight parts on my 2014 unlimited.
That said while GenRight's engineering is great and it is race developed as Tony (GenRight's owner) races extensively. The attention to manufacturing detail and their installation instructions are not up to industry standards. If you have a good mechanical background you will be able to work through most of these issues. I installed their tire carrier and rear bumper, with 1-2 phone calls to GenRight I was able to get it installed. I needed to clearance the rear tail lights for it to fit. I found out later that the aluminum tubes warped some during manufacture causing the fitment issues. Aluminum is notoriously difficult to work and GenRight is one of the few companies that use it. GenRight installed their Aux fuel tank in my jeep and after reviewing the instructions and the installation including the electrical modifications. This is not an install I would want to do myself. Unless you can find a shop in CO that has experience with this install I wouldn't attempt it.
I've installed 2 long arm kits and while they are labor intensive, they are very doable by a home mechanic. Every long arm kit I've seen requires the factory brackets to be cut off. While I haven't installed one of Genright's suspension kits. I would expect that a good home mechanic that has installed at least one suspension kit would be able to figure it out.
My concerns with the suspension kit would be:
1. The installation instructions aren't detailed enough and you will need tech support from GenRight to get their kit installed correctly.
2. The accuracy needed in suspension installs in in the range of +- 1/32", do you feel comfortable doing a welded install with accuracy this close.
3. An installation error could result in a catastrophic failure that could result in death/injury to you, your family and others on the road. The installation needs to be done correctly.
In this thread there is allot of discussion about currie axles. I believe that GenRight uses Currie for most of their installs. Is that where your Currie info comes from? I ran PR60’s in my 07 jeep and will continue to run them in my 2014 jeep. I looked at curries for my 07, but there were some fitment issues that caused me to go Dynatrax. Not to sway you, but I’ll be going with an EVO suspension on my 2014 along with GenRights aux fuel tank and rear tire carrier.
