I bought SS lines but haven't had the chance of installing them. Although I did flush my fluid with Montul 600 prior to my trackday this past weekend. The weekend was rainy and cool, so didn't really beat on the car too much...
Will report back next time I go on the track if fluid alone is good enough. If the pedal feel worsens during the day I will add the SS lines to see the difference.
