oh they are? ill do some more searching but i havent found too much. thanks. i just got my h3 calipers in and they are quite beefy.
outmost to outmost width is 7"
length end to end is 10 1/2"
mounting hole to top of piston is 4"
mounting hole to mounting hole is 6 5/8"
and i know someone wanted piston diamater and that is, diameter outside to outside of each piston is 2 3/4"

 

 

ive stated in the first thread that i dont know how too upload them lol i havent mounted them yet. im doing all of the neccesary measuring first. if you would like to help me then ill pm you pics and you can load them up lol if not then you know what to do lol

 

Its not hard. When you post or reply, just click on the paper clip to the right of the smily face. We are there for ya bro.

 

To OP, nice effort.

If the pistons are 2.75, that would make them 70mm. Nice, it would add clamping force over the stock caliper, and even more than the Z06 twin piston.

BTW, having 4 opposing vs 2 pistons on one side, does not add clamping force if the pistons are the same size.

Very interested in your findings for fitment.

 

If you wanted tiny Brembos why not just use Subaru or Nissans versions?

 

Right and to my knowledge clamping force can be increased by total diameter or increasing hydraulic pressure. I need to measure my stockers because I thought for sure these pistons were larger. Lol if not that's my fault. And as for using other brembos I simply did not want too lol

 

What are they made out of, and what do they weigh?

 

That's the diameter for each of the 4 pistons? Is that accurate? That almost seems unbelievably large.
