For those of you that have some experience with making mounts for brake calipers or engineering knowledge, what's my best choice for metal when machining an adapter for the mounts?
I adapted a set of 13" ZR-1 Corvette calipers and rotors to my Cavalier Z-24 and I used just plain carbon steel 3/8" thick.
Overkill is your friend here. You don't want the caliper to flex under hard braking. Use thick steel for the adaptors and be sure to lok-tite the fasteners.
I've done tons of street cars with 1/4" plate (model As and such), but for a race car heavier is better.. use 1/2" and you'll be more than OK. If you have a milling machine (and a lot of time), you could make a one-piece aluminum mount, but that's a lot of work for a minimal reduction in weight.

Just JB weld it on.

I dunno if I'd trust JB Weld for this, unless it was reinforced with duct tape.

I agree, using 3/8" will work just fine. The cast caliper will shatter before you loose the structural integrity of the carbon steel. Make sure all bolts nuts and washers are Grade #8 that would be the weakest point in your build.
Toyota uses 3/8 plate in their design when they went to larger rotors on their 87 MR2s. Just make sure you can stop, I would hate to be in front of you if you can't:D
JB weld, duct tape AND pink zip ties will work best.

might add a few sheet metal screws, too
just for luck........................................
ha you only need that much when attaching 2 4 piston calipers to a 6" rotor on a 1200lb car.
Sounds like it's nothing super fancy required. I'll see what's laying around my brother's shop and get a supply of pink zip ties for him. I'm sure his duct tape and JB Weld supply is consistent. Maybe even find two more sets of calipers and try to get a triangle going. Apparently there wasn't enough beer during my design phase. VWdmc seems to have that down. There might be enough room...
Home Depot is a great source of caliper bolts....the galvanized carriage bolts are a bargain....or use the leftovers from the Chinese bicycle you assembled for the kids at Christmas...don't forget the Juicy Fruit....don't want the bolts vibrating loose...
yeah cause loctite is a formula derived from bubble gum, make sure you use the long lasting kind, it is an endurance race!
