Hello

I posted a this post in the wrong area again, sorry but here it is.

I have a R32 GTS-T and I live in Japan.

I have to replace my front rotors. They were turned once, but a lot of metal was taking off because the rotors were warped.

I want to buy slotted rotors but my friends(some own skylines) tell me that slotted are good only for racing.

This car is my daily driver, but I would like to go to the track maybe once a month once I get the mods done for my car I want to do.

Are slotted rotors fine for everyday driving or should I get after market stock rotors?

Help please!!!

THe slots vent off gases that are created by the brake pads and rotors rubbing on each other at high speed and pressure, causing a lot of friction and heat. Its meant to reduce brake fade etc. They are fine for everyday driving, but if they cos much more than standard rotors i wouldnt bother as its not going to make any noticable difference in normal day to day driving. If you are going to do a bit of track work then yeah go for it, but a set of better pads will make more of a difference (greenstuff etc)

I have good brake pads on there, but wanted the slotted. My friends said it takes away from the braking surface and not as good as stock for everyday driving.

I can get a set for about 200 dollars vs 110 dollars for a set of stock.

So stick with stock?

the slots are about 2-3mm wide.... considering how fast ur rotors spin as you drive the difference in braking surface area is negligible. Id probably run slotted, if ur doing track days often, but for the sake of $90 just depends on whether u can justify it or not. If ur getting work done on your car, there will no doubt be a car there that has slotted rotors. ask the owner if it made a difference.

Ok I will check more. I know that everyone I speak with (some of the guys have GTRS and modded R 33's say that rotors with holes are bad because can break more easier.)

The slotted rotors I am looking at are not holes in the rotor but just slots cut into the rotor in a few places.

Should I replace the back rotors too? I don't think that they are warped, have to check but want to know if case a good idea.

the ones with the holes are cross drilled which yes i have seen many times they fracture and crack, i wouldnt bother going cross drilled for street... i run dba4000 slotted on mine and they are great

hey guys,

on this topic. so which one is the better one?

RDA or DBA?

i have got a friend who has a slotted RDA rotoe on his car with stock caliper n using endless brake pads(not sure which one). what happen is that his rotor is thinning out (slots are less) the mechanic says the rotors are sh!t and the brake pads are too good for it. tats y the rotors are thinning. his car is not a high performance car. just a ek4 civic. the rotors only lasted one year ( brake pads are more than half used )n he got to change the rotors.

shed some light please....

cheers!

DBA's are generally a better rotor, but at the end of the day its relative to what you want to pay.

I use Endless CCX pads which are most likely what your friend is using too. I do track days with those pads and standards nissan discs (i keep them in on the street too) and they are lasting out fine....so that might tell you something about RDA.

Just by the RDA rotors - they are significantly cheaper than the DBA ones & about the same quality (Not very good). There is a group buy on SAU so have a search for that & save yourself some money.

As for pads if you are predominantly using the thing on the road stay away from pads like the CC-X. Get something that works from cold. Otherwise you could end up in a nasty accident - ie running into someone because the brakes are still cold & you can't stop.....

What brake pads do u guys reccomend beside the cc-x?

just for street and maybe some track days??

ebc brake pads and endless seems popular.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
