The uprights on my car utilize a 3.5" (88.9mm) caliper mount. I know a lot of aftermarket calipers use this type of mount, but what are some good OEM options? I think Porsche and Toyota trucks will work.

I'm not sure of what rotors you are using, but there is a bracket that bolts to the 3.5" spacing that allows you to use a GM single piston caliper. They usually work with 11.75" diameter rotors I believe. Here is the bracket: https://lefthanderchassis.com/v2a/viewproduct_product.asp?idproduct=03218621

911's use them from around 73-89 on the front.

What about 944s, 928s, and boxsters? I was hoping for a two piston slider or 4 piston. Right now I have 99-04 mustang gt calipers on an adapter bracket with SVT Focus 11.8" rotors. I'm looking for something a bit more heavy duty. I know it mint be a slim chance from the oem, but there are some nice calipers out there are more expensive, modern cars these days.
