Yeah. those two "in process" ptictures are of me CNC machining them.

I have about 45 dollars in material into these and another 15 dollars in hardware. And about 20 hours of labor. 20X22.5=450+60=$510.

The body is high-grade T-6 661 aluminum. The pistons are Alpha Ti.

Anyway. I couldn't manufacture these. these are one-offs for my car only. To have someone else make them would cost incredible amounts.

Machinine costs: at least $60/hour
Material: (The same) $60
Plus setup costs + tooling: (approx) $100

Adds up really fast, and I don't have money for startup on something that big.

The pistons are progressively sized in 5mm increments. 20-30. The pads are a wide motorcycle pad that are readily available at a very low price with ceramic backs and whatnot.

Very nice work!!

Will those bolt up like stock, or do you have to make other modifications to the car to fit those lovely calipers?

These ones are made to fit my modified hubs. But the bolt spacing is 3.5 inches and they will fit stock with no problems.

BLASPHEMY!!!!!! ARGH!!!

Yes. Unsprung weight was the plan. And the rotors are top secret. But in the end, I will have shaved of 20+lbs per wheel.

Nice! Why do I find myself lusting after shiny objects of high grade aluminum? Am I the only person with this sickness?

so the mount is on one end, and the caliper is cantilevered off of that?

have you done any analysis on those? I'd be worried of caliper failure due to the leverage of the mounting bolts (to the strut) being offset so far from the pistons....hopefully they'll work fine, it just seems that they'll flex every time you slam on the brakes...
