[QUOTE="silvercoffin, post: 5579730, member: 3749"] [b]more info....[/b] Just found this...definetely goes against what my mechanic friend told me about the break in. Still dont get how a break in is needed for kevlar if it isnt recommended for city driving! Someone explain that to me. organic CHARACTERISTICS Metal-fiber woven into "organic" (actually CF aramid with other materials), original-equipment style.
