Thanks for your reply, i did abit of research and yes you are right, there are certain wheels that has the changeable stainless steel lip, the Kato wheel that i posted from potn has this feature. I've decided to order the Kato's, with Toyo's and delivery it came out to £779, a difference of £159 to the cheaper alternatives. Think that settles it, now at least i know its from a reputable alloy manufacturer rather than a shops own brew.
