The only thing that would steer me away from a LA kit is the extra price. A LA kit probably isn't necessary for that amount of lift, but you wouldn't be sorry.
I have made her well aware of the price difference between a standard and a LA kit (its the newly registered "camogirl" on the forums)... and she seems to not care about the cost as long as she is getting the best she can. I have another friend with a 4" BDS lift on his TJL and the link angles leave a whole lot to be desired. <img src="/forums/images/graemlins/scared.gif" alt="" /> After seeing where the stock short arms sit at ride height on his unlimited, I know I'd be going after a LA kit if it were my truck and I had the $$$.
I also recommended she look into a SYE if/when she gets vibrations after the lift. A CV style rear driveshaft would obviously accompany that mod.
I spoke with Clayton (owner of clayton off-road) for 20 minutes or so the other day and really came out at the end of the conversation impressed with both his company and his product. Very customer-oriented and had very descriptive answers to my technical questions. Didn't miss a beat the entire time I was quizzing him on the design of his LA kits. The Clayton kits
are weld-on vs the bolt on RE... but camogirl's dad will be helping her a lot on the install and he can weld quite well.
I'd use the skinny wheels, maybe even the stock(?) 7" wheels.
I am a fan of the skinnier wheels as well... more for being able to air down further without fear of losing a bead than anything. I originally had the 32's on my OEM 15x7 wheels and they were okay... but the tires did crown some and I wanted to widen the stance some. I can see crowning becoming somewhat of an issue putting a 12.50 tire on 7" wheels. I decided on some 15x8's and they are great with my current tires and will still work later on when I go to the 33-35x12.50 range (most of my purchasing decisions take into account the ability to keep the item after future upgrades in other areas... hence me not buying a front ARB since the IFS is getting torched in a couple of years anyway).
