Just thought I would drop a few pics in here. I recently had a couple blokes wanting these, so I had my laser mate cut me up a few. They are all sold and off to the post tomorrow. If you think you're keen for one, hit me up. If enough interest, I'll make another handful. Material is 3CR12, a low grade stainless. Quite like original rotors, they can rust, but not likely to under normal conditions. 3mm is only recommended for racing situations - for maximum weight savings. It will certainly stop the bike (ask me how I know - LOL), but can warp with continual street usage. 5mm holds up great in street applications! I have over 10,000 kilometres on mine and have had no issues. I supply them with 5 nice Stainless Steel Button head M8 Allen bolts as well.
