Honestly, that TRD edition might impress the uninformed SEMA crowd, but there is nothing really new here.
I love my FJ Cruiser, and have worked on hundreds of them - they are amazing off-road vehicles, but...
We've been installing the TRD superchargers on FJ Cruisers for 6 years, taking off Toyota Bilstein shocks to install real off road suspension components (i.e. Icon Vehicle Dynamics products), and the wheels are not real beadlocks (they are cast one-piece wheels). The TRD exhausts of the past have added zero horsepower - just a sound change and a chrome tip (not exactly off-road friendly, either). And that front guard will get destroyed on the first trail...
For the price you'll pay to get that package from a dealer (especially after the mark-up they'll add to unsuspecting folks not familiar with aftermarket products), you could build a more serious off-road machine.
