I was able to install the suspension as outlined in the instructions using the supplied fitment kits. The only modification is that I had to remove the rear shock guards.
I personally installed the BP-51 kit for the 2010 and up FJCruiser on my 470. Other than using the RCC 2.0 HD springs in the rear, I would definitely use this setup again. The only other suspension I think I would consider is the KING kit for 4Runners. Love my 51's.
