Hey all I was wondering what size the rear caliper bolt was. Like the thread size. I think i need to helicoil one of mine because I torqued it too high.. heh..
 
This is an old post but I cannot find the answer to this question. What is the rear caliper bolt size on a 2005 STi?
I got 7 of 8 caliper bolt to come out clean. The Rear passenger top bolt seized and I twisted off the head.
 
10mm either 1.25 or 1.5 pitch ... Pretty sure its 1.5, measure the ones you got out or take them to the store and match it up.

Or call a dealer and order them they are like 3 bucks each.
 
Did the same thing on mine. Just make sure you put some anti-sieze on them before putting them back in. IF you didn't, I'd recommend going and getting some, back the bolts out, apply, and retighten.

These are aluminum calipers, and steel bolts.

....at least I remember them being like that.
