Well, I finally got all the bushings replaced in the rear and put everything back together.
$4 home depot bushing installer since using a press here was an exercise in futility. It was about impossible to get the bushing started straight without this.
Without the swaybar and shock/spring installed, I used a jack to check clearances at max travel. The first thing to hit is the fender lip, shown here. A slight fender roll/pull should fix this.
Front inside wheel well I have about a penny's diameter from the trailing arm to the tire. This is what I was most concerned about in the rears -- I found one spreadsheet online that said 285's on 9.5" rims w/ 45 offset would not fit and that I'd hit the trailing arm. Not so. The rotors ended up being slightly thicker than the OEM ones too which helped. I'm hoping having replaced the bushings in the trailing arms/toe links with stiffer superpros should keep any dynamic toe-in to a minimum since it would reduce this spacing.
Another pic of wheel/tire fitment:
Overall, I am very happy with how the wheel fills the wheel well. I am not a fan of low offset wheels that stick out too much and give the look of a 4x4. This is the limit of what I consider still looks good.
After replacing the upper arm bushings, it was a major pain to get this piece reinstalled. I had to use a large flat head screw driver as a crow bar to even get this started and then had to pound it in with a 4-lb hammer. Since they are so tight, I'm worried about squeeking.
