Roll yer own bigger brakes (maybe)
I'm using a Dakota based front suspension but it's not a Dakota. So spindles are from the Dakota. I'm putting this up to (hopefully) inform. I think with a different fabricated mounting bracket and cutting down an A, B, C, E or FMJ rotor, the same thing can be accomplished with the Lexus caliper for short money.
Goes back to that "Hot Roddin'" thing. I thank you for the info on the bore sizes. I realize I cannot trim the Dakota "step" all the way back to the hub face because the Ford rotor uses that for centering. I can tell you there is ZERO slop with the Ford rotor on the Dakota hub.
