I have put Fierosail's red stripes on a set of centerline wheels for my Indy. I put them on dry and it is a bit tricky but can be done. It would probably work easier with some soapy water so they can be moved around as needed. When I did it, I cut a ring about 3-4 inches wide, out of hardboard that is just a bit smaller diameter than the machined aluminum ring that the stripe goes on. the idea is that it gives you a center surface level with the machined edge to lay the transfer paper on. ( you will have to experiment with the size of the hole in the center). Then I cut a hole out of the center of the transfer paper roughly the size of the inner diameter of your hardboard ring. Then I cut fairly closely around the outer edge of the red decal, but left a 1/2 inch square tab of transfer paper outside the decal about every 3 inches all the way around. This gives you something to grab a hold of to move and center the decal on the rim before rubbing it down to apply it.
this is all best done with the wheel on a rotating bar stool or turntable of some sort so you can easily turn the wheel as you work.
If you want, shoot me your e-mail and I can send you some pictures that will make all this much clearer.
Hope this helps,
In hindsight, if I ever do it again, I will have a body shop paint them on. It was a bit of work to do this, but like anything else Fiero, the result was it's own reward.
