Braided brake lines for Track Days ?
Figure 30-50 track days per year.
Car: 2016 RS.
Cost with labor - $500
Is it worth it? This was ALWAYS an upgrade on my previous non-P cars.
Your thoughts?

The bad thing about braided brake lines is that they will not give you any warning prior to failure. On rubber lines there is normally swelling and you will start getting a soft peddle due to the swelling.
Not saying don't get them but be aware of the downsides also.

There's two types of braided hoses. The most common replaces the rubber OEM hoses. Pros and cons here as mentioned earlier. I used them on my old car but am not using them now. There are also hoses that replace the rigid steel lines that usually connect the rubber hose to the caliper. I can see where these could be useful for changing pads on the newer "bridged" calipers. Some applications have reported rubbing.

Thanks to everyone for your input!

It all depends if you feel confident downshifting quickly enough to slow the car down to make a turn after a 130mph straight. ..... the point is, when your line blows, you have no front brakes and that is not a great feeling. the car doesnt care if its in a race or on the street, a blown line means no brakes and old rubber lines will blow. new ones.........not so much. i had it happen, after seening the stats on the problems of braided vs rubber lines. i stayed with porsche rubber lines........that decision was probably ok for the first 10 years of their lift.. at 20 years... it was a BIG problem!

I have seen a teammate limp back into the pits with a burst rubber hose, but that was a street car 'banger' based endurance series so that rubber may have been 10+ years old.
Those were later replaced with steel braided hoses. Which didn't fail nearly as spectacularly but when a teammate came in complaining of softening brakes we went to bleed the fronts but as soon as he put pressure on, a thin jet of hot fluid shot out from a wear point where the braided hose had been rubbing against the suspension after not having been properly positioned after the most recent pad change. Made for a long pitstop while we stripped a replacement hose from a non-runner and fitted it.
So I guess I'd say:
Newish Porsche rubber, or braided should both be fine, but take spares to the track either way, and be very careful about routing braided hose to avoid rubbing.
FWIW, the driver who had the sudden blow out on corner entry slowed the car by downshifting and throwing it into a deliberate fishtail. A response that paid off for me too the following season when I lost brakes once going into a tight left-hander.

I wondered about this but one mechanic who does a lot of work with Porsche says that their factory cars always ran with rubber lines. I figured if it worked for the team cars it was OK for me. They should be inspected and replaced regularly, as they are the most important part of the car!
