I would check in with people who road course a modestly prepared car regularly (similar to your street build) and see if they've had any problems with the factory brake lines. If they've reported no problems with OEM lines then go back to them and try for yourself.
Judging by your other post you will be attending National level events, I would not risk losing out on a big win or contingency money over something as silly as a brake line. Probably won't be protested but for someone who wants to move up a spot to win money or a trophy and a hard ass on rules they might throw down the paper. For locals it won't matter and no one would ever know.

Interesting points. I did a little bit of research and it looks like the main advantage of SS brake lines is that they use a Teflon inner hose instead of a plain rubber inner hose (like the majority of OEM rubber brake lines), which actually has more to do with the SS brake lines being less prone to expansion to rubber brake lines than the steel braiding itself.

Anyway, I agree with Jawnathin, I will be removing the SS lines from my FR-S because I will be competing at local and National events. It will be nice to have the chance to get contingency. In KM, the only contingency I got when I got 2nd out of 35 karts at Nationals was $100 from Honda.
