1999 2 door 4x4 too high!!!

[elmapa818]

hey, im a new to the forum and ive read alot of helpful information just by looking through the threads so thank alot to everyone!! but i own a 1999 chevrolet tahoe its 4x4. i was looking to drop it a little bit not too much just a bit because the gaps from the fenders to the tires are killing me. just bought some 26" rims but want to drop the truck a bit but i was wondering how low would it be good to drop it running the 26"s? and can i drop the front to the desired height using the stock front tension keys?? how would i go about dropping the back just a bit? what would be the least expensive way to drop the truck?? thanks
