It's gonna be a while but most likely an evo coil over lift at 4-5" and building some 1tons to handle it. Gonna have to do some major chopping too. Hydro steering etc etc. not completely sure of lift yet though. I'm gonna explore my options when the axles are closer to being done.

I love mine. I upgraded from the Toyo 37s and loved those that I got the same in 40 when Toyo said they were bringing back the 40 on a 17. As for tire pressure....I started running them at 40psi, but I do commute on the hwy alot. May try going down a bit and seeing how I like it.....But at 40psi I think it rides great.

On a 4in Teraflex running 5:38s in an Auto. It's always a work in progress. Need to rethink suspension and axle strength now.

If so, I would not run them over 35 psi, even for extended freeway driving.
Now you got me thinking......Went out and looked at the tire and it stats max 40psi and that it what discount tire put it at. I never changed it but I will be lowering it. Although it's been riding well, hahaha. My 37in Toyos were filled to 50psi by the shop and that was crazy but they were required to fill the tires to the max specifications. I ran my 37s at 32psi and I guess I'll be experimenting with pressures this week.
