SS brake lines are sorta useless for everday driving. You dont need to waste our money on them but if you feel that the rubber lines expand to much or if they wear out by all means go and buy them. If those rubber mounts are under 20$ then buy them, other then that theres really no reason or anything proven that they help wear the pads evenly. And maybe you need to stop pounding on the brakes the second you get to the light. Read the road ahead of you, see a light change yellow let off the gas and put the brakes on way before the light. It puts about 25% more life into them and you dont need to change them every 10k
