Looks great!
I was one of the first Rancho lifted H3's. The guys that did the install had some issues with it. A couple of things to check out is the the way the ride height is set up. Make sure they didn;t crank the T bars all the way up with the lift. I had the same rims you have but in all black and had issue with hitting the steering knuckle when aired down at the wrong angle. (17") It seems the ones I have seen with the 18" setup have been fine. I know that with the proper offest wheel and tire setup that H3 has great AP and DP angles. Also check out how far your bumpstops are form touching in the front. That's how I found out the Tbars were cranked all the way. There's nithing wuite like hitting the brakes hard on the highway and the front dips down a foot.
Good luck with it! It looks great BTW!
How does it ride for you at highway speeds?
