Thankyou for your reply Chloe, however i am a bit confused as to your comments about the DBA4562 rotors. You have said that you have never sold them, but I know of at least 4 people who have DBA4562 installed on their Corolla's now. Is there any chance the rotors will be made in the future? If it is a demand problem, how many pairs would one have to buy to justify the rotors being made? would they be able to be made in a 4 x 100 stud pattern if they were a special order? Thanks for your help, I am just interested in finding a suitable solution to the terrible rotors Toyota supplies and am worried that the standard rotors won't cut it. Thanks again, Michael Taylor
