What is your thought on the SCR porject mu rotor?

I wanted to go DBA 4000 but after reading all these bad review, I'm thinking about paying 120$ more and get the project mu SCR. I already have the 4000 in the rear, should I swap them too or the braking on the rear is not powerful enought to damage the rotor?

DBA are fine in everything including hard motorsport use, I run them on my race car. save the money and buy them

A few years back there was some sort of bad batch of DBA skyline rotors where heaps of them cracked, but there has never been any problems before or since

Both are fine.

After researching the DBA 4000 T3 design and feed back from other people using them, I just went for them.

Also I got them at a good price.

But if you can cash out the funds for Project Mu rotors, it would only do you good.

  • 3 years later...

Had SCR's on the front of my car and after 15,000 street kms and 2 trackdays I cracked both fronts. Was not impressed and would no buy again.

After about 10 days at RAC, Racewars and 3 stints at barbagallo my Project Mu’s are starting to crack, well developing cracks

Looking at the following:-

Another set of Mus

or

DBA 5000 2 piece

Any other brands I should be considering in the same price range?

After 5 years or so my SCR Pro front rotors on my GTR are fine. They have fine cracks in the surface of the rotors - not to be confused with massive cracks that run tot he whole depth of the rotor and which mean you have to bin them.

Also if you buy the Pro series you can keep the hat and replace the rotor and save a few hundred bucks.

Also DBA do not make 5000 series for R32's as afar as I can remember.

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
