Lowered the '01 burb with 3" drop spring in the back and turned the keys in the front all the way down. Looks level so... add some wheels and tires. I opted for the factory size on the new body style, bought Hankook 275-55-20 on a Boss Black Crome 20x 8.5" wheel. Mounted and drive it, the back is rubbing the inside fender liner. What has solved this problem for others I ask ??? The front seems to be OK. What to do ???
