R32 Gtr Sumitomos -> Brembos

[Brood]

I just bought some R32 Brembo calipers and rotors for the front to replace my standard sumitomo calipers.  However it seems that the bolts from the standard calipers don't fit the brembo calipers.  The holes on the brembos are smaller so the the bolts don't fit.  Can someone verify this?? Any help is much appreciated.

I woulds say you haven't got GTR brembos. GTR sumitomos are M12 bolts, 32 and 33 Brembos are M12 bolts. 34 Brembos are M14 bolts. so if the calipers you have bought accept bolts smaller than M12 then there is something wrong with them

Are there any specific markings or part numbers on the brembo calipers that will help me identify it???

I just had a another look at the brembos... The standard GTR sumitomo bolts are the right size except for the pit

h.   It seems as though the pitch of the thread of the brembo caliper is different.  Looks like its 1.5   where as the bolts are 1.25 ???

I'm gonna visit my nissan dealer and to verify this.  But I would like to hear from anyone who is familiar with this situation.

I encountered a similar problem. every one told me the brembos are 1.25 but they looked much coarser to me. 1.5 looked about right. grab some M12X1.5 bolts and see how you go.

I ordered the bolts for the Brembo's from my local nissan dealer.  I got the bolts today.

I have now verified that the bolts from the stock GTR calipers do not fit on the Brembo's.  The pitch is different.

GTR sumitomo's are M12x1.25, Brembo's M12x1.5.

I hope this helps others who buy R32/R33 Brembos to put on normal R32 GTRs.
