i need to buy some new front rotors case one of them is warped. i have the RA65 brakes on my corona and i was wondering what other rotors i could use. i'm looking for slotted or drilled ( but i hear they crack ) can anyone give me some idea of what i'll be needing to pay and what is the best brand to have, keeping in mind as usual i'm on a budget. In other words best bang for buck.
