have had a bit of a look on here for some posts on brakes and there is plenty on calipers and brake pads but was wondering what sort of rotors you guys run???

not talking about big AP setups or any aftermarket set up, was more along the line of RDA's? DBA's? aero tech etc etc but still on a factory caliper.

not really important what car either but some will ask so there for a R32 GTR

really just any general feed back would be great

cheers

My slotted RDAs gave out on the track day, I gave them a floggin yes but I was told but others there that they won't last as long as the DBAs, different metals and manufacturing process apparantly...I've heard some say "they're from the same factory, so DBAs are just overpriced" and others just laugh when I mention that line so I dunno.

I've been through two sets of RDA front slotted rotors, next time it will be the DBA I don't see other track driven cars running RDA and that tells me there is either a reason or most track guys believe in buying brand name, considering some of the cars I've see at track days (low budget trailer hauled cars) I reckon it might be because of advice from others, make from that what you want...

My RDAs were shuddering by the end of a track day they were in their later life and I knew that they would maybe suck by the end of it but I didn't want to thrash the new set I had in the garage.

If someone can support the reasoning to buy DBA please shout it out...

Project Mu are good, cheap & available. They can be had in either a one piece or a hatted 2 piece rotor. They are much better than either the RDA or the DBA rotors. If you are going near a track I would recommend them. If you just drive on the road the RDA's will be fine.

I have had a total of 8 DBA 4000 rotors. They are sitting in a pile on the floor of the shed as 6 of them are cracked. As mentioned earlier it is the return slots that cause the problem. In fact I would (for track purposes) avoid any rotor that has slots that continue to the outer edge of the rotor. I used the RDAs for one track day only & they survived ok. I wouldn't recommend them for continued usage however.

    • H2 (for cars) will never happen. It's not reasonable for any number of reasons. It's also not reasonable for almost all of the industrial uses that the fanbois say that it will be used for, again for a large number of reasons. There are some cases where it will be good. But, even those will be massively hampered by the economics. The only way that H2 can be economic is if we somehow manage to get from where we are to the other side of the economic-valley-of-death in which no-one can operate. You need there to be sufficient renewable generated electricity to be available so that it is effectively free. Once you are there, you can do whatever the hell you want and hang the efficiency. But until you get there, the ever diminishing value of electricity makes it harder and harder to encourage businesses to build the new generation capacity, and they will simply stop investing in generation projects. (I kinda think there needs to be just government money spent on building the required capacity in a non-commercial way, similar to how the first fossil fueled grids were built, as national-government owned utilities. And probably some nuclear in there to start. But this all should have started 10-15 years ago to avoid the chasm of death that we face right now). Synth fuels will be much more likely, but will only occur is there is at least some renewable H2 production, because you need H2 to do it. And you need stacks of free (or at least extraordinarily cheap) energy because assembling molecules back into fuels is exactly the opposite process to burning the fuel, and the reason we burn fuels is because there is so much energy squeezed into each molecule. So you're somewhat subject to the same economic valley of death problem as above anyway. That is unless people are willing to pay the current equivalent of $5 or $6 per litre of petrol-ish liquid fuels. Can you imagine it? The squealing at $2 now is bad enough.
    • This is so cool. Get a dashcam that records audio and hopefully you'll catch it.  Maybe there's a brand or some kind of markings on the back ? Are the pics hand drawn? I love it so much.
    • Hahaha yep, point(s) taken. I just like seeing different things and an EV in an R32 is pretty different. I'm not on the EV band wagon, I'm waiting for synthetic fuels or hydrogen personally. 
    • I mean it's probably likely that people overestimate their skills in dialling in a setup and noticing the changes. I had SK shocks and springs, and added heavier springs and got them revalved by Sydney Shocks to suit based upon what I told them I wanted the car to handle like. I got back a completely different feeling set of shocks, which probably (?) feel great on track but holy hell are they rough on tram tracks and the like. The shock dyno actually looks pretty similar to Shockworks (from what I can surmise from a screenshot of a youtube video - and my dyno printout...) Truth be told I doubt I'd be any faster or slower with either setup, or camber/castor combination. I also had whiteline eccentric castor bushes up front of my R34. I removed them and put in poly non-adjustable ones to soothe my OCD (nobody ever set the castor the same side to side, and it'd be near impossible to do) and be happy the wheel is centered in the well now for clearance reasons. Yes I wanted it to move 1mm 'back' :p I've effectively set my castor back to stock, negating all the benefits of that which is supposedly massive. I've probably also altered toe and camber in a negative (detrimental) way. I can't tell any difference steering the car.
