I have managed to find someone that will sell me some new RDA front/rear slotted rotors for a very good price for the gts-t. They are similiar od and thickness to the DBA equivalent rotors.

Who has used the RDA's and how do they compare to the DBA's??

I plan to use the RDA's for track days with the stock 4 piston r33 gts-t callipers and racebrakes compound pads till i get more $$ for some brembos or ap racing callipers.

Do a search :D:D:D:D

It is a bit hard at the moment but there was a really good thread on these exact things about a year ago. Try searching rotor threads that Roy has posted in.

I seem to recall the general consensus was that they were good value and did the job.

i have used them before and didn't have any problems but i know of plenty of people who have had problems with them. They are by no means a 'performance' rotor. they are just a cheap arse made in china disk.

all depends on how cheap is cheap and how much importantce you place on your brakes.

Denham I hand you your ass at the track using them....and a few guys using the rediculously priced DBA stuff.

Go with them mate. Never heard of a failure and yet the DBA stuff is a bit of a concern in some circles and I do know of failures and a well known race brake expert dislikes them.

DBA sponsor Improved Production in NSW. RDA sponsor same in Vic.

Ive been using the RDA stuff for a while and like them.I havent used them for circuit racing but use them for drag racing in one of my cars which uses green stuff pads and they work well cold braking at 140mph. I had a bit of a bad run a few years ago with dba rotors where they would start to shuder and stuf after a 1000k's of hard driving and whenever i rang and asked for a reason why it was happening i was allways told it was because of brake pads or not being bed in properly. So i tried some cheap rda rotors and never had the same problems again.

Jeff u think the gtr size 325mm od fronts of the rda can be used with an adaptor to fot on the gts-t like the dba gtr ones can?

The GTR ones are not much more but are alot bigger.

Denham, consider the thickness as well. Are they 33mm compared to the 30mm of the GTSt size?

If they will fit then do it. Get the spacers made and enjoy. Might be some extra cost in the final solid brake line elbow mod though.

I know brisby is using some 5000 dba's with adapter and apparently working well for him. Is racebrakes the only place that sells the adapter?

So ur using the rda gts-t replacement front rotors right? How many track days have they seen and what condition are they currently in? I can get them for $150 each front and $75 each rear.

whats the final solid brake line elbow mod required?

Mine are not DBA 5000s, they are only the 4000s. Race Brakes no longer do the adaptors, it seems that RB - Vic isnt a fan of them , so stopped doing them based on the fact that they feel it is to much a compromise.

Be careful when grabbing too thick a rotor, you may find you are needign to machine down the pads so you can get them to fit, as the calipers may only be designed for 28/30mm etc rotors

Both the 4000 and 5000 fronts are 30mm thick.

I am talking front rotors here not back.

How else do you fit bigger than 296mm front rotors on a gts-t?

MILD TRACK USE WITH EBC GREENSON

THE MAZDA,

A MATE OF MINE USES THEM ON HIS E30 RACE CAR WITH

EBC PADS AND THEY LAST ABOUT 70-100 HARD LAPS

DEPENDING ON WHAT TRACK,

FOR A WEAR AND TEAR ITEM THEY ARE PRETTY GOOD

VALUE FOR MONEY

do they need the alloy hats to fit or are they direct fit?

No they are not alloy hats, especially not at that price.

The thickness of a GTR disc is greater (33mm) than the GTSt so I'd be concerned if they are selling that size in a narrow disc of 30mm. Maybe just an option for GTSt but not for GTR.

The dba 4000's for the gtr are also 30mm thick.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Boost cut after swap(RB25DET NEO) R34

      By Duncan · Posted

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
