If you do plan on tracking often, I recommend getting a full front wrap. There are plenty of reputable installers that do quality work. This bra or even a template cut clear bra (shows lines) will not fully protect against track tar, rubber, huge bugs, sand/dirt kicked up, etc. On the track, you will get crap past the bulge or even on the roof with elevated tracks. I got mine full frontal and picked up a bottle of TLR from Premier. The best stuff to get tar/rubber/etc off clear bra. Regular bug/tar remover wont do the job on clear bra.
Besides, you're not gonna want that bra for your track day photos
