hi, the company i work for just put in a big laser and im planning on doing a little work on the side with it. my question is this: what type of steel do companies like braking, galfer, etc... use in their rotors? im planning on drawing up some wave rotors and oversize rotor kits. if they work well on my yz450 and my friend's crf450, i might start selling them on ebay or something. i want to make sure they are good quality before i start selling them tho. thanks for any help. i really appreciate it.
