    Yes, they're 4 piston. These are the calipers:

    I dont know the diameter of the discs off hand but I'll try to measure them tomorrow.

    EDIT:

    Actually after a little research, I believe these are the rotors:

    The biggest issue with the stock brakes is not clamping force (calipers). It's the solid rotors which cannot dissipate heat effectively. Any serious brake upgrade for the Delorean will upgrade to ventilated disks.

    My VIN:    897 5 spd,

    I've seen spacer kits that for our brakes sold from Europe (evidently those calipers were used on solid and vented rotors in Europe). That said, the fronts are easy to space/widen since they have fluid on one side only. The rears require new plumbing to the other side. So making the brake calipers "work" is relatively straight forward. The problem is the disk. The other problem for the rears is the parking brake... specifically the Part #:109034 Retraction Plate which needs to be widened.

    This sounds wrong to me but maybe I'm missinterpreting what you've typed.

    Both front and rear calipers have 2pistons, one either side of the disk, and the fluid operates them both, not like some modern, typically small, cars which have a sort of floating caliper arrangement.

    The spacers Ed used to sell which allowed you to widen the gap between the pistons and install thicker/vented discs, were just that, spacers, which allowed the fluid to travel to both sides of the calliper.
    It was actually a very simple and elegant design which allowed the use if oem calipers, with your preferred pads, but with the space to accomodate thicker vented discs.

    Apologies if I'm missunderstanding what you are trying to say.

    Thanks for clarifying. The fronts do not use an external tube to route any fluid to the other side... they use internal routing that the spacer must accommodate That somewhat simplifies spacing the front caliper spacing. Note to anyone interested...I've seen spacers that have only two holes, the holes for the bolts. You need a third hole for the fluid. The rears use a tube to port fluid to the other side.

    Nice!! Inquiring minds want to know the rest of the details.

    Josh,

    I tried the wildwood four piston calipers about 15 years ago on one of my Delorean's and I found the four piston calipers to have to much power for the car ie they would lock up. I did try them with both the original brake bias and the aftermarket 50/50 bias on the brake master cyl with no change. I am using them now on the EV delorean as I have added a lot more weight to the car and most of that is in the front end. In regards to the drilled front brake rotors all I have seen have been home brew drilling and they tend to make a grinding noise when the brakes are applied.

    I think this has been answered but for clarification...

    So, other than "home brew" vented discs, there are no current vented discs for the stock braking system, correct?
