As for thermal mass, the OEM front rotor is 360x30 mm whereas the AP front rotor is 368x36 mm - significantly more thermal mass along with more vanes on the AP rotor (72 curved vanes).
OP - glad to hear you had a great time during your first track day This is when things start to get really expensive

Do you know how many vanes on stoptech 380 rotor? I love APs design while Stoptech is lot cheaper. I saw so many corvette on the track day has stoptech kit. And those cars have more than 600whp..
