Looking at upgrading my braking system (32 GTST Mspec) in the near future. Have been eyeing off a set of Project Mu 6 slot rotors, but was told the DBA's werent too bad, and may be a cheaper alternative.

Anyone had experience with either of these rotors, maybe even both and can give me a bit of feedback ?

Also if someone can recommend a decent caliper upgrade to suit would be very greatful, planning on running the standard master cylinder but can upgrade if necessary, already have braided brake lines and run a good quality Motul Fluid and decent pads.

Have had a quick search of the forums in the appropriate section didnt really come up with anything, cheers.

Hmmm i'll definitely look into the RDA's, so far have had some mixed reactions about the DBA's so im a bit hesitant. Project MU or RDA are the front runners at the moment, I think the RDA's come in a little cheaper too will try and find a supplier tomorrow and make some enquiries, thanks for the help guys...

No recommendations on calipers or master cylinder upgrades ?

Put the new pads and disks on and see if you still think you need to upgrade the calipers.

slotted rotors are a good upgrade, but perhaps you should consider larger calipers and slotted rotors to match (as mentioned, r32 gtr or r33 gst-t or brembos's perhaps)

also, what braking problems are you having? are you getting brake fade? alot of people contribute poor braking performance to the actual brakes but often it's the tyres you're using (if you have no problems locking all 4 wheels up with abs unplugged...)

Its more a case of security :O 500hp with standard R32 type M brakes... leaves me a little scared at times ill admit.

Have had some fade problems after some good spirited driving through mountains and a few instances slowing from high speeds. Other times where I would have liked to slow down a bit faster, but I attribute that to having some less than friendly rubber on :P

All this is going to be compounded when I take it to the track (which are my intentions) so I'd like to get it sorted prior to taking it out there.

Other then perhaps competitive pricing, why are ppl so keen to be using RDAs and Mu rotors?

If you are running slotted DBA 4000s you will never have any problem...im kinda partial to using the Kangaroo Paw rotor design before just plain straight vane vented rotors.

I did see some Brembo replacement rotors for the Z32 300ZX that were curved vane...and they were reasonaby priced....

the mu scr pro has something similar to the kangaroo paw, though just short straight sections as opposed to the more diamond shaped dba type. There area also a lot less vanes in the scr pro, so reduced weight.

And they are pretty 2 piece rotors. C'mon roy, i know you have a brake fetish!

    • Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA
    • I'd want at least $40K for mine, but thats easy to say cos I'm not selling anyway.
    • That's incorrect. We have 4 seasons, consisting of pre winter, winter, post winter and a small glimpse of hope! 
    • I spotted a black C34 in Mittagong this morning!
