R33 GTR Brembo Bolts

[CMR]

Had a search and can find a few threads about the above subject, but no definite answers.

I know there are a few people on here running GTR Calipers, what are the bolt sizes did you use for the front? I don't want to have to get the standard bolts machined, would rather buy new in the correct size.

I've read on various forums people saying its both M12 x 1.75 x 40mm and M12 x 1.50 x 40mm. Can anyone definitely confirm?

Cheers

When I had R33GTR fronts I used the bolts that came with the callipers when they were on the Skyline. I can't see why you need different bolts. If they were R34/Z33 then they are bigger so you have to either drill out the hubs or helicoil the caliper

It's the shank on the GTR bolts that is longer than the shank on the S15 ones.

They are definitely R33 GTR calipers and M12, its the pitch/thread size I could do with confirming as all I can think of otherwise is getting the Skyline bolts shank's threaded which I'd rather not do.

Still don't see why it's different tbh. S14 and S15 use the same hubs so if it worked on my S14 it should work on your S15

I got 33 gtr calipers on mine and it didn't come with the bolts.

I just got some high tensile bolts from a fastener specialist near me, job done.
