[QUOTE="patooyee, post: 444865, member: 483"] [b]Re: Re: Re: Re: Re: Rockwell disk brakes[/b] They may not flex. The ones that flexed were a long time ago on Dibble's rig. Wilwood has come out with several new affordable lines since then that are a lot more rigid. Some of their new forged stuff is pretty solid.
