I bought stencils for the logo from someone on this forum a long time ago. The stencils don't include the red line, I just taped that off myself. The stencil is like tape with the logo cut into it. You stick it on the caliper, paint the logo, and remove the stencil. I would worry about the heat melting the glue on a sticker or emblem. I used 500 degree engine paint and it has held up well on the roadcourse. I did the same with my other Supra (with no logo) and after 3 track events and about 25,000 miles they also looked like new.
