March 6, 2008I'm the same height as you and I am able to reach the ground perfect. I used the TJ products 1.5" lowering kit with stock shocks. I also got a Danny Gray weekday seat. That made a big difference. The front has been lowered 1"also. Most recently I installed the Arnott air ride system that I absolutely love. http://www.arnottairride.com/products/makeDetails.asp?makeId=16
They have 2 systems. I got the $689 total shipped package. Easy to install also. It utilizes a 12" shock and can be lowered on the fly 2.5". Check it out when you get a chance.
