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.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
