Madman did mine. You have to cut and reroll the front part of the wheel well. You also will have to cut the back of the wheel well. You will need a big hammer to do some rubbing inside the wheel well.

1. Get the fenders opened up. Alot. I had mine professionally done.
2. Take the bump stop off and bump stop bracket.
3. I then mounted a 30" X 10" tire on a weld 10" rim with 7.5" back spacing and bolted it up as best I could. Marked the areas that needed clearance and went to town with a grinding wheel and a hammer till I was satisfied.
4. Took it to the drag strip, made a full pass and checked for areas that needed a little going over.
5. They still rub a little

i plan on using a 30x9 radial slick. on an 8 inch wheel, so i don't think i will have any problems on the inside but the front part of the lower fender might hit. i have already removed the rear bumper support and rolled the metal back and cut the bumper to clearance the 28x10.5 MT slicks. just need to know what to do with the front. i might make a visit to mad man on april first when i go and pick my son up from tomball.

In front you need to move the existing lip back to where it is flush with the wheel well. Cut out a pie shaped piece push back the lip and weld it. If you do it right, you will only need a slight amount of filler.
In the rear you will only need to modify the facia and the metal behind it. Again, take out a pie shape piece and move the lip back.
Once you mount the wheel and tire, you will see where you will need to use a heavy hammer to move the metal back at the inside front of the wheel well. The radials will not grow as much as a bias ply, but it is still a good idea to check for rubbing once you make a pass. Also watch for body roll damaging the outside of the tires on the lip.
I have had good luck running Hoosier radials. They last me about 35 runs without problems. The Mickey Thompsons were a little faster, but would only work for a few passes before they went away.
Good Luck,

Now this is a wise thought.
