Steel rotors on 370z?
 

I read that the 400z proto will have steel rotors. Does anyone know where I can find them for a 370z base trim and how much difference they make? If not can anyone point me to the lightest rotors they know of for the 370z base trim? Thanks

Proof that a little knowledge can be a dangerous thing

The brakes on your car now are fine, bro. Stop at red lights and stop signs, look both ways before crossing. Signal before turning. Recycle.

I think my brake pads and rotors will need to be replaced soon and wanted to find something good for the purpose I use the car for on the street. It is my understanding that a big brake kit only helps with repeated high speed stops (over 10). I don't track the car so I'm looking for some other kind of upgrade since my rotors probably need replacing soon anyway. Reducing the rotating weight (with lighter rotors for example) would probably improve things.

If you want to up grade the rotors. Up grade the calipers too. Most people with the base brakes go with the 'bono calipers with stainless lines.

In what way exactly do the akibono calipers improve braking? I think the braking distance will be the same because I can lock up the rotors already with stock calipers. Will it make high speed braking more stable or reduce judder? Or is it mainly to help keep the brakes cooler, to allow for more stops without losing braking distance?

That makes absolutely no sense :icon14:

The sport package brakes have an extra piston in the calipers along with bigger pads and rotors vs the base brakes. The extra clamping force and larger pad contact surface area contribute to significantly improved braking capabilities.

Different tires and their wear condition can also significantly impact braking ability.

I'm guessing the improvement is only during high speed braking then, in situations where the rotor is rotating too fast for the calipers and pads to stop it completely. Once the calipers and pads are able to stop the rotor, it is up to the tires to stop the car.

If you're suggesting that the sport package brake setup with Akebonos does not provide greater braking capability than the base brakes at low speeds, that is incorrect.

The difference will be less at low speeds and greater at higher speeds. Whether that difference is worth the cost to upgrade is entirely up to you. But there is a difference. Simple physics at work here.

The tires and brakes work in tandem to stop the vehicle. Not one then the other as you have stated above. If the calipers stop the rotors before the vehicle stops, you're locking up the brakes which means they are not able to do their job as intended.

Just get some replacement rotors and new pads for your base setup and call it a day. There aren't really any options for you to upgrade elements of the base setup without moving to a larger kit. Pads are about the only variable to choose.

If you get the Akebono setup there are some lightweight options, such as the Z1 two-piece rotors.

I've got a stock set of the big brake rotors barely worn I can sell you. I just replaced mine with new drilled and slotted rotors and my mechanic mic'd mine and said they were still great, they're just sitting now.

Trying not to make assumptions here…..what exactly is your usage of this car?

Really just want some improvement in stopping ability and smoothness on the interstate. Daily driver but I drive fast sometimes.

Your brakes shouldn't be affecting "smoothness" Turn or replace your rotors if they are shuddering during braking.

Go full Akebono or just get some decent street pads. Your stock setup should be fine on the street as long as you're not an idiot. The Akebonos will give you better performance at fast speeds.

Smoothness…..if you have judders during regular braking, you highly likely have pad deposits on your rotor. Be light on the brake pedals at stop light on hot days.

For commuting, you won’t feel shxt spending that money. For your use, objectively, at the most, I would switch out to a slightly sportier pad that has better bites and heat tolerance for that one-time emergency stop on the interstate (but will get way more brake dust thro).

Functionally, I don’t see the need for any upgrades.

pretty sure OP is asking about steel vs iron rotors in regards to reducing unsprung weight.

sort of an interesting subject if you want to do some reading, but irrelevant for the use case described here.

If you weight lightweight. Get carbon/carbon brake set up. Hope you're a trust fund baby.

I was hoping for something that costs less than the car... What are the lightest rotors for the base trim brakes? Or what are the best street performance pads and rotors for them anyway.

Just get some OEE from your local parts store and stop overthinking it. Standard blanks and OEM pads or Centric Posi-Quiet pads should be fine. If you get anything else expect a lot more brake dust on your wheels. If you have money burning a hole in your pocket get the Akebono setup.

Maybe also try doing some research on your own instead of asking to be spoonfed information. There are other threads on this topic. It does not appear that you have read any of them.

No lightweight options for base rotors.

Have you been smoking your pads? What’s your complain about your current pads?

There is no steel brake rotors. Just cast iron. The best cast iron rotors are RacingBrake. But not for you.

I'm getting a little pulsating and juddering with high speed stops so I think that means I need new rotors. Just wanted to get some opinions on good ones. I'm using ebc blue pads. They stop well but do make a little squeaking on occasion at low speed. I don't think I will benefit from akebono calipers since I don't track the car or go fast more than maybe 10 minutes at a time so I was looking for other options.

Might be able to have a shop turn the rotors for you without needing to replace them. EBC blue pads are fine but you should know those are a streetable entry-level track pad. You might want to switch to a ceramic pad instead of a semi-metallic if you want less noise

The Centric Posi-Quiets won't bite as hard but will dust less. Hawk Peformance Ceramic pads will still bite decently and are not as dusty. EBC Red and Green pads are good stuff, too. You have a number of options and just have to decide what's right for you based on your needs.

No, bigger brakes does not exactly equate to better stopping distances. Pretty common misconception.

Your tires and even suspension is where that comes from. Having extra pistons on a caliper distributes the force on the pad and rotor which reduces heating for heavy brake use (many hard braking in a short time or lots of weight from a heavy car or towing something). As long as the brakes have the ability to overcome the traction of the tires then there is effectively no difference in a single emergency stop situation.

Which is why this guy is fine with the base brakes. There's a lot of variables that go into braking, of course. I realize an earlier statement I made is not exactly clear - it was a response to a statement I misread.

The time that it takes smaller brakes to reach that threshold vs bigger brakes is quite small, I'll give you that. But in an emergency situation, that can mean the difference between an impact or not. All other things being equal, that is.

It is always better to have more brakes, then less, or None..... LMAO!!! Don't skimp out.

I'm starting to hate light weight brakes threads as much as oil threads. There are may other places you can remove weight for less money and less headache.

It's a bigger deal for performance to reduce the weight of moving parts though.

Lol, Nismo#91 is weeelllll aware of that fact.

The real question is why does it even matter to you? You're not doing time attack. You'll never be able to quantify (much less notice) the weight loss on the street even during spirited driving. The car is plenty capable as is.

Man you drive an automatic, stock Z base model that is not used in any performance driving situation

Get your stock replacement rotors and pads and let's back off this bench racing talk

If you want to talk actual braking performance upgrades, head to the track forum and they'll tell you to get new lightweight 18, sticky tires, a better pad compound, 2 piece rotors, sport calipers or better, some better fluid and SS lines, and ducting, along with coilovers and the SPL package

All of which you aren't gonna do

So why are we playing around?

Go to autozone, spend a couple bucks, and enjoy your trip to school/grocery store

I can tell the difference between when I have a spare tire in the car and when I don't so I'm pretty sure I will be able to tell the difference if the rotors are 30lb lighter from using a material lighter in total than iron. It would make even more of a difference on the rotors because the engine has to rotate them directly just to make the car move. I don't think there is a lighter material available for the base trim rotors. To get lighter rotors it sounds like I would have to first upgrade to the akebono brakes and swap in some carbon fiber rotors that would cost 15 grand for a set... Hmm not worth it. Was just hoping someone made steel rotors or that there were more options for light rotors at a reasonable price. It's really just for ***** and giggles. To keep myself entertained really.

Just looking to make the ultimate commuter/grocery getter without breaking the bank. Most upgrades won't make any difference for that. There aren't even any tracks where I live.

it's absolutely ridiculous that you're talking about the marginal performance benefit of rotors when you are doing absolutely no performance driving, you are being a total bench racing poser

if you DID want to drive the car fast, there's way more crap you'd need to learn and worry about then ******* rotors

You drive your car on the street with no performance context, just replace your brakes with autozone stuff and put the bench racing crap away

Why are you assuming I don't drive my car hard occasionally? I didn't feel it necessary to explain everything I've done to the car in terms of straight line performance.

I don't know who **** in your cornflakes this morning but come on man, it's his car, he's perfectly allowed to run a more performance brake setup if he so chooses without justification to you or anyone else.

I don't track my car yet I opted for the lightweight z1 rotors, are you going to call the performance car police on me too?

.

Before this thread gets shut down...

I have 2 piece rotors on all four corners. The only way you will feel the weight difference is on the track, IF you have track experience. You'll feel a greater difference in how the car handles by installing lighter wheels. That's money better spent on building a nice daily driver anyway.

I cannot, under any circumstance, recommend someone buying a 2 piece, steel, or carbon rotor kit for street use only.

Got to post the cat.

Couldn't find anyone who makes a steel brake rotor for the Z. Did find out the you have to use pads made for steel rotors. Because of the different friction coefficient.

I could tell the difference when I put on 2-piece rotors on all 4 corners. But that is just me. You don't have to be on the track to be able to tell the difference.
