The real fix would be to pull the leveling blocks and have them shaved by another 1/4". However the 1st set the company sent me (ebay) made the front set up 1/2 higher than the rear. When I called them they offered to custom cut a set and overnight them to me. Pretty good customer service!! These came in so I had to take the FJ back over to the shop, have them pull the 1st set and install the 2nd. Which now is perfectly level until I get weight in the back. Don't get me wrong it's not terrible but I would have thought they would have taken into consideration added weight in the rear.
I'm not sure if having an off-road addition with 16" wheels apposed to the 17" wheels is an issue with some of these leveling kits???
