I know on the evo front brembos calipers it is m12 1.75 I know cause yesterday I got new bolts for my future brembo swap.

For stock calipers, 1g and 2g dsms are m12 1.25 if memory serves.
if you plan on replacing them with hardware store/parts store bolts, make sure they are grade 8, on the head of the bolt It should say 10.9 on the head of the bolt like this see picture below.

you also should get new hardened or best grade lock washers, and hardened or high grade washers, you don't want these backing out on you.

Thanks alot! that is infact an odd thread. haha
Just for curiousity what´s the lenght of the bolts for the evo swap?

Sorry for the late reply man.

The stock length for the evo 8-9 brembo caliper mounting bolts are 35mm long [longer then dsm bolts].

Dsm caliper bracket mounting bolt length appears to be 28mm long, or at least that is the length on my 3kgt brackets that I have handy, I'm pretty sure it is the same on the stock 1g dsms, the length might be different on a 2G, but I doubt it much of it all looks the same.
