I am stationed in Northern Japan ( Air Force) and ordered a 2002 blazer xtreme. Auto, locked rear end with 3.42 gears. I have been over here for 3 years and haven't even seen an x in person, just know what i've seen on the internet. Anyways, I pick it up when I get back in August and want to start customizing it right away. I would like to get the performance mods first and was wondering what bolts on will give me the most improvements and what I should start with. Thanks for the help.
