I plan to upgrade my 2013 tt tires to 285 75 16 Nitto Trail Grapplers, I spoke to two places that both quoted me in the $1300 dollar range for all 5. The thing that confused me was I was told that I needed to install a leveling kit. The place I talked to said that they wanted 700 dollars to raise the front 3 inches and raise the back 2 inches, because I need to have new springs added as well. My Fj only has 44k miles on it with the upgraded TRD suspension on the rear so why would I need new springs. I found a leveling kit online for 220 dollars (link: https://www.amazon.com/Supreme-Susp...1479134865&sr=8-3&keywords=fj+cruiser+3+front) How much do you guys think someone should charge to install this? Thanks!
