Hi everyone,

I've got a brain teaser question here. Not sure if anyone has done this before, but i've got myself a brand new sets of front Ford BF XR6 Brembo calipers. Now this is the hard bit, I'm trying to fit these calipers on my R34 GTT. I have got no rotors yet thus, will have to buy new Brembo Rotors to go with them. As i've got 18" Nismo LM-GT4 rims on, I would like to get a bigger rotor than what the XR6 rotor is. I remember reading about someone commenting about the biggest size rotor that you can fit in a 18" wheels and also commenting that because the nismo LM-GT and/or Rays TE37 has got good brake clearance, supposedly you can fit a little bigger rotor than nomal wheels... i remember the person also commented on the actual figure/dimension. But i can't seem to find the thread on this topic!! I've looked upside down, inside out, offsets, wheels & offsets, brakes etc etc....After searching extensively, i've given up and therefore asking for all of yous to help (if you know the answer).

Question 1: Has anyone fitted an XR6 Brembo setup onto a R34 GTT before? From what i can see, I would need to fabricate some sort of bracket to fit these calipers especially after i increase the rotor diameter. Caliper clearance should be no problem.

Question 2: I'm using a 18" Nismo LM-GT4 rims thus, what is the largest diameter rotor/disc that i can fit in them?

Question 3: I'm based in Melbourne. Do you know of anyone that can do a good job in Melbourne?

Thanks guys. Great Forum!

Cheers, Mike the happy R34 GTT owner. :D

Anyone? Anyone that knows the answer? I was told that the biggest rotors i can put in there with the 18" Nismo LMGTs are 355mm rotors?

Anyone that can help me with the above questions? Promise will post them on the forum once I get them done ;)

I still haven't bought the rotors yet. So, don't have a price as yet.

if u dont mind me asking how much were the rotars?

Try Harrop if you are in Melbourne. Also Racebrakes.

Check the disc offset - I am not 100% sure that the BA matches the Nissans, but I think that it does. If it does you can get a large range of rotors (hatted) made by proper companies like AP Racing, Alcon & Harrop themselves. Oddly Falcons use the same PCD's as Skylines.

Not sure why you would ever want to go larger than 355mm, however.

Thanks bud. I will try those 2 companies as suggested.

Does anyone know if I will haev to fabricate a new hat to fit the rotor or can I just buy brembo rotors with different offsets pre-hatted?

Also, would 355mm definately fit inside my 18" wheels? I remember reading somewhere that GTT comes with 310mm original rotors at the front?

Lastly, I've got a price of $600 for the Brembo rotors from ProTech Automotive in Preston. He couldn't remember the size of the rotor quoted though, so, I'll have to get back to you on this once he confirms it. Reasonably price?? Anyone knows??

Thanks heaps guys!

Mike.

Check the offset on rotors for the BA's in the DBA catalogue. You can then compare this to the Nissan. If they are the same you will be onto a winner.

Definately? No. Probably? Yes. You have to remember that the width of the caliper is just as important as the rotor diameter. Make youself up a template & check it.

$600 for what? Hatted rotor? Cast rotor? Grooved? 28mm or 32mm wide?

Posted this a while back, problem with Falcon discs is hub locating hole and stud size.

GTR height 53.75mm centre 68 pcd 114.3

GTP height 50.5 (355 diam ) centre 71.8 pcd 114.3 larger studs

Chrysler SRT 8 height 53.5 mm (360 diam ) centre 72 (32mm thickness, DBA cattledog min 31.8mm. misprint?) centre 72 pcd 115 mm

Viper SRT 10 height 59.6 (355 diam ) centre 73.6

C6 Corvette height 45.5 (355 diam) centre 70.7

You might be able to get some undrilled DBA5000s and have them drilled to suit. Should work.

      Thanks Santa (the neverending trials of the 400,000klm, 400kw, RB30, manual swapped Stagea)

      Thanks Duncan! Yeah it's street use for me only. Maybe occasional track day. Any difference in noise when running with the two pumps? I would expect the lift pump to be more quiet than the main pump so hopefully not? And yes, unfortunately quite a big price difference to the simple hanger setup. Though I'm usually willing to trade money for better reliability and future-proofing. Buy once, cry once and all that. I'd be very happy to never have to deal with fuel pump / wiring issues again

      The old manifold was quite under the GTR strut brace.  The new manifold is quite [unknown] the GTR strut brace. The GTR strut brace was needed to clear the bonnet vents. The Old strut brace will almost certainly clear the new manifold, but not the bonnet vents. The old strut brace will almost certainly clear the new manifold, and the new bonnet without vents. But I am hoping the GTR strut brace clears the new manifold :p

      Bonnet clearance?

      On the bright side, at least you knew that it happened and remedied before anything happened. A friend of mine just took his Fiat 124 to a shop for an oil change and they didn't tighten the oil filter housing properly. 4.5 quarts spewed out and even after refilling + tightening the cap the engine has a tick now.

      So, more pain. The FAST manifold is a little larger than the stocker. This is problematic because there really wasn't much clearance to begin with, so going from 'barely enough' well into 'no' is sad based on the external dimensions of the thing, even though where it bolts to the head is the same. Result is the fuel rails sit a good 25mm higher, and this is a bit of an issue with the wiring that runs behind the motor, and the fuel lines, and everything else. When pushing the manifold on, it required a huge amount of force to crush wiring looms to fit it, sensors like the MAP sensor are about 1mm from the firewall, and the FPR just has to bend ABS lines to be forced into place. After some brainstorming and some sad drinking, the loom for some reason ran from the grommet behind the ABS sensor, then to the driver side head, then back to the passenger side head. So all of this was pulled back and stripped, a few wires cut and rejoined, so that the 'branch' was now on the passenger side's head as below: Before you basically couldn't see anything behind the driver head. This is much improved! The MAP sensor is now pointing up (instead of at the firewall) Brackets have been made up for the rail. The rails are for a LS1, the manifold is designed around a LS2 as it's base. Which of course has slightly different bracketry and water pump clearance, hence the mods people need to do. Should be hopefully mounted tonight. I spent money on a new FPR that is slightly more compact than my Turbosmart FPR1200. The gauge has also been moved to the rail. There's also apparently an ORB to AN Union instead of the adapter, because the ~25mm of the current adapter is going to make the difference. Provided this all goes together and arrives today, it'll be the totally not stressful attempt to start it.
