My order for some front rotors for my '98 C43 got cancelled. iRotors called me yesterday and told me that the manufacturer wouldn't have any available for a few weeks. I couldn't wait so I cancelled. They order blank rotors from a Co. called Bradi and then they send them out to be drilled/slotted/zinc coated by somebody. If anyone knows of any other aftermarket supplier of front rotors for my car, PLEASE let me know!!!
