12" brakes

[chadswe4]

How can you install 12" brake rotors to fit on a TR with stock upper and lowre control arms.
Maybe cutting off the rotor part and just using it as a hub and putting a 12" rotor from a vett on.
What do you think.
Thanks
Chad

You can do this, but you need to make Caliper Brackets like BAER does or like 1LE cars came with and drill and tap holes in your stock spindles.

Do you or anyone else know who has done this or know of a site that I can look at.
Thanks

Poke around on Wilwood's website. You can download a PDF with the installation instructions for their front-end kits, including the kit for the G-Body.

In that PDF file is a scale drawing with measurements of their bracket, which is a big piece of plate steel. Their kit uses a stock-diameter rotor, but you can get the needed spindle modifications off the diagram, as well as how to drill the plate to fit on the spindle.

You'll have to figure out where to position the caliper mounting holes on your own.

Bracket?

I would like to do this conversion, but I hate to "reinvent the wheel" to make a bracket when somebody else already knows how to do it. Seems like a good thing for one of the vendors to do, should be reasonably cheap, since it's just plate steel.

Anybody with a drill press and a plasma cutter can make the bracket in the links posted by UNGN in 30 minutes.

You're right, it is just plate steel. If you make it yourself, it'll cost you maybe $50 in raw materials if you're nice to somebody and they give you some scraps.

Brake brackets sold by MSA for converting the rear drums of my 240Z to disc are $250 a PAIR... for "just" two pieces of plate steel. I see the same thing happening here.

I'll look around in my carport, but I'm pretty sure I don't have either one. I'm also pretty sure that most of the turbo Buick owners don't have them, either. That's why I thought it would be good for someone who DOES have that equipment, and the dimensions of the bracket, to make them available to the rest of us, at a reasonable price. And I agree, the $250 Turbo6inKy mentions is NOT what I would consider "reasonable", not by a pretty good margin.

The best bet is check with the Monte guys on this. Someone may already be making them in his garage.
