I made the exact same changes except I'm still using the stock rotors. No problems during or after my track day. In the mornings I have to pay attention during the first few stops because they don't grab like the stock pads. After a few stops they work like factory pads on the street and much better at the track. I keep thinking about a big brake kit. But so far I haven't seen the need. Perhaps after I get stickier tires on the front. What tires are you using on track days?
