Default ARGH! My jdm sti brembo calipers will not bolt up

Okay I got the H-6 rear brake upgrade done no problem, then I started on the jdm sti front brembos and ran into a rather significant snag. Everyone here on nasioc seemed to think they'd bolt right up on a '02 wrx but it seems the thread pitch on the bolts that held the OEM brackets on is wrong.

It will only thread maybe 1 turn before it snags and I'm afraid to force it because I don't want to damage the threads on the caliper. What size bolt (length x diameter x thread pitch) do I need to purchse to get these new calipers to bolt on?

You want the sti caliper bolts. Go order it from the dealer. Not having the right bolts... how does that make it not bolt-on?

I was hoping I could snag the right bolts from a local auto parts store, so I can get the calipers on and drive the car to work tuesday. The old bolts look like 12-1.25mm and 30mm long, maybe some with a 1mm thread pitch would work? I tried to save money ordering these used, I guess you get what you pay for...

Well, you want the proper grade bolts. Otherwise bring them along to the hardware store and add in the thickness of the integrated caliper bracket.

I would bring your caliper with your when trying out bolts. then you can try them out on the spot. I've found that NAPA has a very good selection of bolts as well, if your hardware store doesn't have anything for you.
