Jay,
I can give you the process that was used when I reworked the prototype vehicles; it works better then the templates. My question to you is this, are you going to make a new inner wheel well like the one shown earlier in this thread??? If you do not it is likely that the tire will hit !!!! Second there are three components that were used for clearance to the front tires. First the new wheel well inner (that we just talked about), second was a spacer to push the stock plastic wheel well liner forward (an easy bracket to make). Third a new plastic rear wheel well liner to prevent you from rubbing in that area (not easy to make). You can see this on your friend’s car.
All this was done to prevent any interference in the wheel well area with the new wheel offset and tire size changes, required for all potential driving conditions. You can probably get away from doing some of this and not have any problems driving but I would not recommend it because I have not built a vehicle without all the revisions just mentioned.
If you decide you want the instructions for reworking the fenders I will try and post it this weekend if at all possible.

Regards
