Hi all,

I have an r34 sedan non-turbo (not using turbo brakes like in the GT-V).

My rotors are in need of being replaced soon and I'm tossing up between slotted rotors or just the plain (genuine) ventilated rotors. I want to know if it is worth spending extra for the slotted rotors (DBA 4000 series) or if I'm just wasting my hard earned $$$. I'm intending to do all 4 corners. I mainly do city/freeway driving, on the odd occassion i take my car out to the Black Spur or the Great Ocean road for some fun (guys in Victoria would know these places :P )

Also wondering if there is a difference on the life of the rotor (slotted vs plain).

What are the recommended pads to go with the rotors? I was thinking bendix ulimates or would these be too harsh on rotors...

If your going to the trouble of changing the rotors, i would just put in slotted...

You really only need them in the front... however it does look better if you do all 4, and not just 2.

I dont think they are that much more from memory...

Just dont get the ones with the holes in them... augmented i think they are called, as disc around the holes tend to get fine line cracks due to rapid heating and cooling.

so ya +1 for slotted!

There are 4 types. Plain (no grooves or holes), slotted (grooves), drilled (holes) and slotted and drilled (obvious, isnt it?)

Slotted wear your pads down a lot more, but drilled are more prone to cracking. However, the drilled do allow for more venting, so they do serve a purpose

DBAs have a reputation for cracking, even their slotted rotors. I think most of the people doing it are doing it on the track though.

If you're only doing GOR and the Spurs you should be OK. I would assume, and hope, that you're not pushing your car to the limit on either road and overheating your braking hardware. There's not much margin of error available on either road, and with GOR especially help can be very far away.

Thanks for the tip about the rotors cracking - its got me thinking :)

I try to be gentle on the brakes where i can by using a lower gear.

I wonder if anyone else here has experienced cracking fo non-track use?

Thanks for the tips guys. I've bitten the bullet and going for DBA slotted "4000 series" up front and DBA slotted "street series" for the rear. They are on order, I'll update you guys on what I think of them.

get slotted and drilled mate look so much better and a lot better performance, you will not have any dramas with them cracking unless your thinking about drifting or track days ?(unlikely being n/a)

You can also get them cryo dipped (ask your brake specialist about this)

+1 Slotted and Drilled (countersunk)

i havnt really heard much of a difference between the 2 unless u doin some serious racing but my point of view standered ventalated is arite. plus now brake pads dont use aspesdos anymore they use fine metal particals in the brake pad so rotars dont last as long as they used 2. slotted do look better if u got money go for it if not just go normal cause rotars some are luky to last 80000km.

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
