Fitting 34 Brembos To A 32 Gtr

[Kaido_RR]

that's a good point. but I bought the following:

a set of 34 brakes (included 4 X calipers, 4 X rotors, all pads, all brake lines).

out of that I'm going to throw out the lines (re-use my 32 GTR nismo lines), throw out the brembo pads (switch to something more suitable for me), and machine the rotors (they are about 50% worn).

and I needed 4 heli-coils (bought a pack of 10 for $15).

and I bought a 33 GTR master which cost around $120.

now an AP or Brembo front and rear kit for 32 GTR is up around the $8000-$10000 mark depending on which particular caliper and what size rotor you want. It will be better, no doubt about it. But so far I have only spent less than a third of that $$$. and that includes

savman, the 33 master I bought second hand. Think it cost me around $120.

good point but you seems to get all your parts from japan surely you could have found a cheap ap racing kit over there lol

[Beer Baron]

sadly there is no such thing as a 'cheap' AP kit even in japan.

[Kaido_RR]

Hey Beer Baron, i was hoping you could help me out?

Im looking at putting R34 GTR Brembos on the rear of my R33, what needs to get them to fit? are they like the front and need the 14 to 12mm bolts?

And where did you see them? (yahoo auctions??)

Cheers Michael

[sav man]

why would you want R34 Brembo's on your R33, or is it a Gts-t

[Beer Baron]

rears are heaps smaller. like 8 or 10mm bolts.

I didn't buy them from yahoo. just a guy who was upgrading his R34 GTR brakes front and rear.

[Beer Baron]

btw, one trap I fell into. it seems the R34 holes are 14X1.5 NOT 14X1.25... d'oh.

can anyone tell me off the top of their head is the R32 bolts 12X1.25 or 12X1.5?

its an gts-t

i have ap's on the front, so wanted to upgrade to something larger on the front

beer baron, so will the rear bolton without any modding?

12x1.25 richard.

So there is obviously 1 difference between the 33 and 34 brembos, the 33 ones come with 12mm bolts not 14 they went straight on our car once we removed the backing plates.

But I haev exactly the same problem putting my old gtr brakes (12mm thread) onto the volvo to replace the crappy silvia single piston calipers - the volvo has 14mm like the 34 so I need to drill and tap out the gtr calipers to take a 14mm bolt too. I need to check if there are x1.25 or x1.5 before I tap it now I guess lol

Dave I'm sure you're right about the helicoil working but it scared the crap out of me on brake bolts......

thanks duncan. that's what f**ked me. trying to stick a 1.25 pitch heli-coil into a 1.5 pitch hole (well i had run the 1.25 tap through but it didn't remove all the old thread).

duncan, if you want to put the 12mm bolt calipers on a 14mm hub, check one of my posts earlier in this thread. you can buy a kit with 12mm bolts and small sleeves so no need to convert the calipers or the hub.

Ps, I was at nathans the other day and picked up some nice cheap 33 brembos. i told nathan to tell you thanks... all jokes aside I had a look at your bremos sitting there and they are definately a coarser thread than 1.25. it looked like 1.5 or even 1.75.

[Duncan]

lol at least they are still there - I figured it was time they got rebuilt they have had a hard life....

I don't get yahoo japan....where can I get some of those bolts - do you know who makes em or if someone imports em?

Or I might talk to nath about machining up the sleeves here, the right bolts are easy enough to get.

[32R]

Hmm look like 12mm bolts with a sleeve to me... Have you taken that picture to coventry to see if you can get something off the shelf?

^^^^maybe try there Duncan

Could someone tell me if the rear calipers of a R34 Vspec11 bolt on to a R32 Gtr?

I know they run a bigger rear disc but I dont know if the caliper has a different PCD..

Thanks

(dont mean to take over your thread Barron but it is sort of related )

[Duncan]

the calipers and rotors bolt straight on to the 32

[Beer Baron]

well a little update.

I bit the bullet and got some timesert steel inserts put into my 34 brembo front calipers. and I can confirm 100% the thread on 32 GTR bolts is 12X1.25 and 34 brembos are 14X1.5. The steel inserts are a good idea. much stronger than helicoils and probably even better than the original thread cut out of the alloy. now I just need to get my discs back so I can put them on

[Ronin 09]

I think you need to harden up, Count...

[Yawn]

Reviving an old thread here, but can anyone confirm this statement with regards to vspec2 brembos?:

Duncan Posted 3 Jun 2007, 08:26 PM

"the calipers and rotors bolt straight on to the 32"

Reason being I read on gtr.co.uk that the late model r34 gtr's (which im assuming a vspec2 is late enough of a model) have rear brakes that are the same as 350z ones, which dont fit?

I'm pretty certain beer baron mentions a difference in the DBA rotor cracking thread. Found it. Page 5 if it doesn't link straight there

[Yawn]

Thanks for the help, but BB only mentions that the N1 34 gtr has a larger rear rotor in that thread.

Doesn't necessarily mean anything- whether it fits or not?
