DBA 4000 slotted rotor?

[Roy]

How long would dba4000 discs last, how many times machining before it needs replacement?

Im running the DBA4000 off an R33/34 GTR on mine, so bigger rotor in theory means lower temps so perhaps a bit better wear then what you would expect from the DBA 4000 for an R32 GTST, std-280mm vs GTR 324mm.

But as an indication i just had my rotors machined for the first time about 5 weeks ago after 3 years and about 80,000kms (approx give or take 5000kms?!?!?!)

They have done about 30 track days with RB74 pads and were wearing great and had never been machined.

Then since December last year i have been running Comp 9s and after about another 3 track days with the more aggressive pad finally needed machining.

So based on how long they lasted before needing the first bit of machining, id say i still have plenty of life left in them, though i have found the RB74s are harder on the rotor, so would guess i only have say another 10 track days and 20,000kms left in them.

Why?

Of course you can.

If you can that's great !

I chat about stuff like this with another newbie like me at work and we bounce ideas back and forth. That was his idea that you can't machine 'em.

So I had to ask to see what others thought.

Thanks

These rotors have good feedback from those who use them.

If you all keen to get one, I saw there's a thread on group buy for these DBA rotors... check the Group Buy section.
