right, so basically i want to try designing and making my own disc rotors, possibly to try and market if prototyping if succesful. just knocked up a quick design idea... so, any suggestions/improvements before i actually make make a prototype? and if i test out a proto and feel its reasonably safe anyone else fancy doing some product testing for me in the not-too-distant future? nothing special about the design really i guess, just want to make them pretty pimpin' and i guess i could sort out some customization if it all goes ahead.... so yeah, comments really?
