SS lines for a firmer pedal?

Just got back from another trip to RA and noticed my brake pedal gets softer towards the end of the braking zone. EX: 135mph - 50mph from 275/300ft out.

Would SS lines help keep it firmer? I'm using motul 600 and hawk 5.0 pads so I don't believe i'm over cooking the breaks....

I doubt it has anythign to do with the brake lines. You should really look at running HP+ or better pads in general. 5.0 is a street pad comparable to OEM but with more initial bite/torque.

Reality is that you probably need to vent the brakes somehow if you are getting pads that hot. Add some ducts, bend the heat shields back, etc.

I planed to run ducting before this event but ran out of time, instead I took off the entire heat shield. Not sure how well it actually helped cool the brakes.

Ill look into some better pad options.

It isn't a heat shield so much as a debris shield, and it's supposed to aid in ducting air towards the center of the rotor so it can travel out through the veins of the rotor to cool it...at least that's the theory. Might want to look at this thread https://www.e90post.com/forums/showthread.php?t=889192
