1. Saleen rear wing would be a good choice
2. Cobra rear bumper is a must, whether you fill the letters or not
3. Remove all decals. Do not wrap, that color is very nice.
4. Replace mirrors with 03 Cobra mirrors
5. I would change the wheels too but not a must.
1. sticks a bit far out the back to me, currently looking for Cobra trunk lid and spoiler
2. I will talk to a local paint shop about filling the letters, I don't want to drive around with Cobra on the bumper if it is a GT
3. Decals will come off in winter. I will wrap it, my paint is not in great shape and I want something crazy.
4. already done as written in the original post
5. Saving up for a set of HRE R101s - may take a while though
