I have about 6100 miles on the stock brake pads with stainless brake lines. I mite do 2 track days at road atlanta, will it be a good idea change them or should they hold up? I'm in a very fast beginner class and i don't wanna chance it. If you guys recommend i change them..which brand and type do you experienced track guys recommend..what if i don't get the required 250mile break-in for new pads..will i still be safe at the track? Almost forgot..I have about 2 hrs of track time on the stock pads. [:0] thanks
