With the car setting on the ground on the 28" tires i used a ruler and measured 1.5 inches from the tire. Then I walked the ruler down the tire holding the marker at 1.5 inches making a cut line on the bumper cover. I used a dremel with a saw tooth disk to cut the plastic and a cutoff disk for the metal. ill try and post the pictures today

Please pardon the rubber I was at the track on sunday and the car is REALLY dirty
You can see that I still rub a little on the top. I dont rub at all in the front. On the other side I dont rub in the back at all, but I do rub a little in the front. I have adjustable LCA's so ill be working with that some more. There is some metal on the inside under the plastic that had to be cut, This winter Ill be cutting some stainless to cover the hole. I can weld it to the inner fender.
it looks like right now

One thing to remember is a lot depends on your LCAs, rubber bushings will let the rear move enough forward on the launch that even 'two fingers' of clearance will rub. Same on the rear bumper when you slam on the brakes.
Even poly bushings move some, rod end LCAs = very little trimming for 28" tires.

I have the spohn poly-rod adjustable LCA's. One thing that may have made me have to trim more than some others is I used the 7.5 inch convo pros rims. This rim is to small (even though many posted on the board telling me they worked well) This small rim pulls the sidwall in pushing the center out giving me an artificialy larger diameter.

When I get the new rear bumper on the car, I'm going to redo the clearancing. I'll keep the leading edge of the bumper (the piece that koolrayz cut off), do my clearancing, mold it back onto the bumper and then spray it. I think it'll look a lot better.
This is what I've got now...
