Hi guys,

was looking at the RDA rotors group buy and had a thought whether i could get R34 GTR sized discs and put them on my GTT, ie oversize the standard OEM diametre...

Not sure of the rears but the fronts are 324 vs 310mm comparatively, but the height difference is only .05mm, which doesn't sound huge but i don't know, could be a massive difference.

Would it be a stupid to run oversized rotors on standard calipers? I thought it might be a cheap upgrade because i doubt there is much difference price wise between the GTR and GTT discs.

If it is possible, would it be a huge headache to modifying whatever to make the GTR sized discs to fit?

cheers,

daniel

anyone? i'm looking to burn KRudds money on my car and this might be a place...

my logic at the moment is that the GTR rotor price is VERY similiar to the GTT RDA rotor price, so why not go bigger if it's the same money?

what i don't know is how much of a headache it will be to fit...

no you can't. the radius is 7mm different. the only way to do it is to get a bracket to mount the caliper 7mm further out. but you can't obviously as the bolt holes will be more than 7mm. so it would have to offset the caliper to allow you to bolt the bracket to the hub and the caliper to the bracket. considering you are trying to save money, then i would give it a miss. making custom brackets to gain 14mm rotor diameter is not worth the $500 it costs you.

RDA rotors are pretty cheap troy. maybe $200 or so for a pair of slotted GTR sized ones. there is a bloke flogging them on the forum in the group buy section.

thanks for the responses guys :P

I was told i could using something called "dogbones"? that mean anything to anyone?

There wasn't much of a price difference between the GTT and GTR rotors, so that got me keen. I think it was mid $400's all up? (4 discs)

Sounds like it would be too much $$ to make the brackets. Thanks for the info :(

right o, so if i can find some already made for this sort of application then maybe it might be worth it...

where'd you get your dogbones from and were they pricey?

cheers,

daniel

yes dogbones are brackets, but for good ones your looking at $400+ for them. there is no way you'll find some off the shelf to run a 7mm diameter bigger rotor. it's just not worth it. you could get them made but you're looking at $500. and again it's such a small difference it's not worth it. if you were running 280mm or even 296mm rotors it may be worth it. but 310 to 324 is NOT worth it. if you want to waste some money on gaining 14mm in rotor then by all means dig in. :D

no thanks. Been to Race Brakes before and will never go back. Harold was a tool, the guy working on my car chipped my rim getting one of the caps off, and basically i was told to run some $600 a pair Endless Ceramic pad to fix my supposed brake issues. So much for a supposed SAU Vic sponsor :laugh:

And from a few people i've heard the opposite, the DBA's aren't much chop and to go RDA's. And considering how many people have gone through the Group Buys for the RDA rotors, surely a bunch of people would have problems by now if there were issues with them.

I think i'll probably just go with he Group Buy RDA's in GTT size, keep my QFM A1RM pads i've got now (very similar compound to the RB74's i believe, but cheaper) and perhaps call it a day. Maybe get some braided lines as well. Already got a brake stopper thingy.

thanks for all the help guys :(

best idea of the thread. :laugh:

done. Thanks for the help bubba, but ze baron is making sense and i didn't know they were that expensive.

ok, moving on. Thanks all :P

No worries, I'm with teh baron on this too - in my case it was 296mm to 324mm. I put some DS2500 pads in at the same time so I can't say how much better the bigger rotors or pads are but together, they were a hell of an upgrade over the 296mm rotors + bendix pads.

Oh and slotted 324mm rotors look better than non-slotted 296mm rotors :D

interesting...

i still havent cracked my RDA fronts, and i rate RB74's over endless SSS(FWIW)

    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
