dhousley,
I'm a noob when it comes to Land Cruisers, and have a few questions on yours:
1) with the suspension change, did it raise it by 2"
2) what is your ground clearance underneath?
3) what's the largest size tire you think you could put on your LC without significant rubbing?
My current vehicle is a '08 Wrangler with a 3" lift and 35s, and it is fantastic off road. I've been waiting on the 2019 Wrangler with the diesel engine, but your build has me intrigued in terms of off-road capability. I'd like to have at least 12" of ground clearance, but that may not be feasible with an LC.
Also, if anyone else has any other insight, I'm all ears.
