You have one sweet rig in progress there my man. I love my T-4 V-6. Im more of the "spirited" type, who likes his speedy stuff, along with some knarly uphills too. When I shopped for tires, I was debating between a few different tires. I really wanted the TOYO M/T's but my issue is, its my daily work truck and I put alot of city miles on her. My choice was an A/T. But I needed an aggressive a/t with a nice soft rubber compound to suit my driving,(sprited) style.The new TOYO A/T2's came out one month after I picked up my Nitto's. Nitto's, not a bad tire on or off. When aired down just right for most all conditions, the Nitto's, like your A/T2's perform well for an a/t. The key though, is to air down. If you dont do that now, you will be amazed at the ride, handling, and amazing grip. Im talking fast powerline's with fast corners, to sandy silty washes, to knarly uphills. That is one thing I dont see when we are out, it guys airing down. Not airing down will cause more drivetrain damage over the long term. I guarantee that!
I went with the 5100 adjustables up front and the 1.5 daystar and the 5100's in the rear. After a very short time, I grew to absolutely hate the OEM springs. For off roading with all your gear, passengers ect, the rear OEM springs are horrible. Even with my daily work supplies, they dont handle the weight well. Or any sort of rough or slow to meduim speed roads without bottoming out far to easy. The trade off though is when you are climbiing that nasty hill. Thats when we need a soft, compliant chassis setup allowing the parts and pieces to articulate easily. I cant wait for my new springs. But, your rig is dam sweet!:thumb3:
