The 11.75 Rotor will go on the later model e-Body & a-body spindles. Correct?. And these spindles fit any e-body. Correct?  So all that would be needed to upgrade to the larger rotor & better calipers would be an adapter. Correct?...Sooooo what would be wrong with fabricating an adapter (especially for non OE calipers) out of say 1/4" steel or 3/8" aluminum plate?  Some of the adapters I see being sold separately or as part of a kit seem to be nothing more. If my a$$umptions are on target the caliper options would be wide open.
    What am I missing?

Yes, the 11.75 rotor fits right on to any B, E or post 74 A body disc brake spindle.

Also, adapters are just some simple machining on some healthy steel stock. The biggest challenge would be getting the dimensions right to properly fix the caliper where it needs to be depending on whether your using a fixed or floating design. Wilwood kit pictured. They appear to have started as a big, thick block. It may actually be easier to make brackets to bolt to drum spindles since they have a flat face.

Cool thread, I like how you have the weights listed.  Even though they aren't in your swap setup, if you want some more weight data the Wilwood billet SL6 calipers were 4 lbs on the same scientific bathroom scale.

Just curious, what do the 11.75 rotors weigh?   The two piece Wilwood 13x1.25 rotors and hats were 12 lbs.

Maybe you should try to find a job at a place like XV Motorsports or something of the like?   

That would be cool, but I'm not too hip on relocating and there is nothing locally comparable. Something I learned back from 01-04 when I was selling parts is that you have to move a butt load of product to actually make a living doing it. Much more than 1 person can do in one day on the web by themselves. There is much more money in being a point of origin manufacturer or an installer. But, I am looking into the feasibility of a more automotive based career.

When that RMS order comes in,the brakes will be on the top of my list.   What about master cylinders?  What do I need to run four wheel disc Baers? Lines?   


Wilwood and Baer both have some nice master cylinders and you can find them in polished billet and other fancy things. For just practical functionality I've always liked the Mopar units. You can choose them with a built in bias to reduce the need for rear brake proportioning, they are lightweight, and adapters make them a bolt in deal. Any of these are compatible with 4 wheel discs. For lines, there are becoup repops out there in plain steel and regular stainless or polished stainless. Again,  a bolt in deal. Of course you could always make your own too. I've done that before just to alter stock routing and clean up the layout.

Just curious, what do the 11.75 rotors weigh?   The two piece Wilwood 13x1.25 rotors and hats were 12 lbs.

11.75 rotors weigh 25 pounds each. That cast iron hub just kills em. I've always really dug the way Wilwood's stuff looked. Very trick. I asked ARE if they were considering doing adapters for Wilwood GN calipers or making a Viper brackets to 11.75s fit disc spindles and they said no.
