right now i have the ls stock rims off an 03 with 235/65/16's on em and im just gonna leave those til i get the tahoe 20's. also im seeing that all the coils are for v8's and theyre saying itll sit lower in the back
If thats the case then if you do 2" coils and 2" spindles you may be around 3-3.5" upfront. You can always just get some 3" coils and 2" spindles and a flipkit which would be 5/6 but in a v6 it may put you around 4". Not real sure about v6's though. Since you have 16's you have to get the mcgaughys 16" spindles and then will need to grind down the lower bj stud and maybe a bit into the nut to make sure you clear the 16" wheels up front.
