Looking to pull the trigger on a wilwood big brake kit here soon and was looking for some input from people running the kit. Are the drilled and slotted rotors or Spec 37 race rotor options worth the extra money? The car will be daily driven (less than 12k a year) see a few autocross events, and hopefully some full on track action 2-3 times a year if time permits. Any and all feedback on rotor choices would be appreciated!
