Scat Pack 4 piston Brembo calipers and rotors

Here is a picture of the Viper kit that I used to sell. The rotors were off a Mercedes S class, the calipers were from a Viper and the brackets were made from aluminum. They were basically just some aluminum bar stock with some holes drilled and tapped in them. This was all designed in MasterCAM 2D and made by local machine shops. The brackets didn't cost me much to have made, maybe $40 each.

Out of curiosity, I worked up a bracket to fit the same Mercedes rotors as above but with my hubs (cut down rotors) to mount the Viper caliper I have.

Using a 2"x1.25" bar, 6061-T6 material and machining done by Xometry which includes tapping 2 of the holes, the quote came out to $131.24 each if I get them machined in the USA and $88.29 if I get them machined internationally. I could save a little if had the holes just drilled and tapped the holes myself, which might be necessary as it appears they are limited in the available thread pitches.

Not an apples to apples comparison as my hub doesn't put the rotor out as far as yours so my bar stock might be smaller, but I have more meat around the holes that might be unnecessary. Either way, a bunch more than $40 each.

I shutter to think what it would cost to have them do the below bracket.
