SRT-8 Brake lines?

Does anyone know what the flexible brake lines running to the calipers on the SRT-8's are made of? Are they rubber or Stainless Steel? I had a race driver from Skip Barber tell me these are some of the best brakes they have seen. She said she pushed the car hard for four hours around a track and they didn't fade. Sounds like they may already have SS lines, but if not I may add them. I live in a high traffic area with lots of bad drivers, makes for a lot of emergency stops. You can increase your braking distance, but then someone cuts you off. Which means another emergency stop. I suspect the brake boosters are pretty powerful to feed these massive calipers. Higher line pressure will soon take its toll on rubber lines. Which may cause them to stretch over time.
