Dba Vs Project Mu

[`nigno]

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.

a lot of people are running DBAs and seem happy. you might also try RDA, lots of people are happy with them too. brake upgrade - try R32 GTR rotors or the Brembos off the R33/34 GTR.

I've got Project Mu SCR R32 rotors combined with project Mu pads on my 180 and I love them, couldn't fault them

One thing i hsave noticed is that Project U etc are straight vane rotors...the DBA have theoir own patented kangaroo paw etc rotor. Not sure which is better, but im pretty sure a curved vane rotor is superior to both for cooling.

i would either go RDA or the mu's i have rda's there awsome get some Mu's pads maybe but my rda slotted front where about 270 for the pair

bargain

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 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

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!
