i have a 97 4 door blazer 4wd and i want to lower it and run it on some 20" Boss 304. i need to find out how low i can go with out doing too much work and spending too much money? also i would like to find out what profile tire i should use when its lowered?

 

Depends on how much you want to lower it. Stock height you can get away with 255/45-20. With a slight drop you will have to run 255/35-20. Any lower then you have to use irregular size tires (less than 255 with a low profile wall) or go to 18" wheels.
