1998 R34 GT- N/A coupe brakes??

Recommended Posts

Hello  Everyone,

After fully forging and building my r34 2 door rb25de neo to a turbo conversion...  i would like to do a brake disc and caliper upgrade.

I know for sure for sure for sure there IS a thread  somewhere that i read a couple weeks ago but i just spent a hour looking for it and no luck.

My question is, can i buy brake discs and calipers upgrades for a r34 GTT coupe? (cant find aftermarket shit for the NA r34)

i think i heard something like the N/A brakes on the r34 is actually r33 gtst brakes and discs.

If anyone can give me some advice or even direct me to a thread it will be greatly appreciated!!

Yes. What I can't remember is if they'd given up on 4 stud wheels on the NA by the time they got to the R34. If you have 4 stud, then it is a lot more work and stuff you need to get - because the turbo stuff is obviously 5 stud.

Nope.

NA R34s were still sliding caliper junk. R33 GTST are 4 pot Sumitomo on 296mm x 30mm rotors.

 

There's a lot more than one thread covering this stuff on these forums. Use google to search the forums. You will get much better results.

Mate, you are not searching hard enough or not reading the entire threads. Try this on this forum 

R34 Non-turbo Rotor Size And Pads

and it will lead you to this

Read the threads in their entirety otherwise you miss stuff.

if you want cheap Brembos and don't want to pay the GT-R tax, get yourself 350Z Brembos calipers, Rotors :)

They will sit a bit future out compared to the GT-R ones, but if you've already got some decent wheels you'll clear it.

Oh, here's a guide I wrote many years ago:

I'm also not sure if the R34 NAs went to the 14mm caliper bolts like the turbos did. If they are still at 12mm, then fitting R34 turbo calipers requires changing the threaded inserts in the calipers.

If the NAs are 12mm, the you could fit R33 calipers easily enough (on the 296mm rotor) or you could fit R32 calipers (preferably using a dogbone to push them out so you can use the 324mm rotor - which you CANNOT do nicely with the R33 caliper).

The info on 12/14mm is available on here. I just can't remember.

Habib, if you read the guide it will make sense.

No thread inserts, those are gay.

Not talking about helicoils or similar. Talking about the entire press in threaded boss. I pressed out the 14mm one on my 34 calipers and put in some 12mm ones that BenC34 had made up. So as to not have to drill the car.

I put helicoils in my R34 Brembos. Calipers haven't fallen off, even after a few track days.

Yep.....not the appropriate application for helicoils. There is a particular drill size and tap for every helicoil. Slopping them into the wrong size thread is sketchy.
