1979 911 SC Brake Rotors


Vehicle Information: Model: 911 SC Targa; Year: 1979; Body Type: Targa; Total Mileage: 135,000;

I am going to need new rotors soon. I am autocrossing and intend do some time trials. For money reasons I need to stay with the stock calipers (so I can race stock class). I am looking at slotted and cross drilled rotors which are allowed in class. What is the advantage of each? The ads promise the same advantages for both types. For my street and autocross use what would you recommend?
