I did a search and couldn't really find any help.

My free brake warranty is over on my '04 6mt Sedan and it's time for the rear brakes to get replaced. I've been waiting for the warranty to be over to do some sort of a minor upgrade.

Please keep in mind I am not looking for some sort of major BBK as I do not track/autocross my car. I just want something that handle a little more abuse. Overall I found my brakes to be very good, grabby (although not as much as when it was new) and powerful enough, but I always feared that their miniscule size would lend to quicker fade leading to warping/glazing

My 2 thoughts are:

1. Try to find a used set of G35C or 350Z Track Brembos (seems nearly impossible) to swap out to.

2. Rotor upgrade kit w/ Caliper relocation bracket from Racing Brake (http://www.racingbrake.com/INFINITI_s/2445.htm)

Those seemed like the only cost effective options unless someone else knows any others. I'm leaning towards the RB setup, seems like a better rotor setup, but on the other hand the Brembo calipers must be better (although not like a true kit I know) and I can always get better rotors for them. Either of the two should work behind my stock 17's which I want to keep for winter tires.

Also, my fronts got new rotors about 5K miles ago (under warranty) so I was wondering if there would be any problem keeping the fronts stock until they are due. I would obviously upgrade them once they are done.

Any feedback would be greatly appreciated. Thanks in advance guys.

 

Don't just change out the rear rotors if you're going for something larger if not different at all. It'll just mess up the balance in your braking. when you go into hard braking, you could easily lock up the rears if they grab hard. you won't need to worry about brake fade if you're not going to be autocrossing or anysort of track racing.
my suggestion is to just save your money and get yourself some nice set of pads. Be wise in your choice though. track pads will need to warm up for optimal performance. Also creates a lot of brake dust if you're worried about that. Just find yourself a nice set of street pads that do a better job then the stock ones.
Hope my minimal knowledge helps you

 

I'll change the front ones if I have to, so as to avoid probs, but it sound like ur saying to stay stock except for pads. I do need new rotors as well so I fugured why not do the upgrade now.

BTW, I also failed to mention that I have found myself doing some high speed braking on occassion, still not the repeated abuse of autocrossing.

 

u could just get some slotted rotors

 

Why do you need just rear rotors? are they damaged? Brake fade is only due to high fluid temps so you might want to look into new brake fluid which can withstand high heat. i'd suggest starting off with a nice set of pads and fluid. And if you feel the need for more stoppage, I guess then, you can get yourself a set of larger rotors for all four wheels.
if you feel like upgrading your rotors will give you a better feeling for safety, you should go with it, Its your moneys!

 

This may help address some concerns about caliper relocation kits.

I'd get some name brand slotted rotors (they don't have to be too expensive) and some good pads. You can do that all for less than $400 is you look around enough, and that's including fluid change, which you should do.

 

My suggestion to 04NismoV35 would be to just upgrade the pads to some aggressive street pads. I think that you will find all the benefits you are looking for by upgrading the pads. With some Axxis Ultimates, you will have a higher max operating temperature. With a higher max operating temperature, it will be more difficult to get uneven pad deposits which causes that "warped rotor" feeling.

Some lines will get you a firmer pedal feel, and slotted rotors would keep the pads from glazing over. Upgrade the fluid to Motul RBF 600, you'd have a much upgraded brake system over stock for your type of use.

We have all these in a packaged Stage 2 kit. Please see any of our resellers for pricing.

Just a quick eBay search...

Rotors:

Pads:

Why not just spend like $500 on 4 new XD and slotted rotors and 4 sets of Hawk HPS pads? Then you have new brakes all around that will last longer than ORM. I mean, I'm a new G35 driver, but just seems like a better option than $1k to $2k on brakes if you aren't track-ing it.

 

04NismoV35,

Thank you for your interest in our products, and their should be no concern at all with upgrading to our OE caliper kit. We have an article explaining the principle of how our OE caliper kits are built and the difference between us and the competition. The article is easy to understand, with examples of OEM and aftermarket upgrades using the OEM caliper configuration, please read:

My business is incredibly time consuming and so this is first chance I've had to read and reply. Sorry for all the back and forth. I just want to avoid spending money in vein and want to get it right, not messing up the the things I DO like about my stock brakes.

Is that enough honestly? They still seem too small for the car.

40K on original rotors that have been cut once already and they supposedly have a lip (according to the dealer) I should confirm that myselft though I guess. Maybe I can get away with just pads until I need to do the fronts (new pads and rotors @ 35K) then I'll worry about the 4 corners.

I have read that and it was pretty useful reading. It seems that the concerns are realted to the brackets that add on to original caliper brackets. The one I'm interested in is a single piece replacement design.

Logic would tell me that if you increase the diameter of the rotor and are stopping further away from the center point, then there should be better/increased leverage for more effective stopping w/ less work. Maybe I'm reading it wrong. Obviously other factors matter like the material being used (pad & rotor). I know I would need to change the lines to work with this kit and I guess the only other thing that bothers me is that the rotor thickness will still be the same.

Your thoughts?

Are you running that setup? If so how do you like it. I did years ago with another car (PowerStop and AXXIS MM) and wasn't thrilled with the feel and stopping, less fade yes, but not better stopping. I actually like and think that the stock setup stops well, I just don't think it can put up with repeated stops. Any combo suggestions?

This is sounding more and more convincing. I was already planning on SS lines. Question...do regular lines tend to flex more over time (giving softer pedal feel) as hot fluid passes through and softens them?

I've thought about it, but don't know if it's enough or that much better. I keep reading the the dust is much better with the Hawks but the stopping isn't as good. I for one would rather stop well then worry about a shiny wheel that I could always clean up if I cared that much. I was considering their $500 (per axle) kit which isn't that much if you think about it. Not tracking, true, but I am a very agressive driver and do want to keep my options open for future light tracking. My bro had HAWKS and didn't like them and switched to ceramic pads. I saw your other posts, did you get them? How do you like?

I'm glad you're chiming in. I was looking at using 1-piece setup. What are the benefits of the 2-piece setup? Diferrence between slotted only vs. XD and slotted? Any pad recommendations to complement your rotors? What about using ceramic pads? Any danger just doing the rears until the fronts are due? I just had the fronts done for free 5k ago, would rather make the most of them. Would you say that the RB relocation kit is somewhat track worthy?


Sorry for the looonnnngg replies and thanks to all for your input.

 

The main benefits of two piece other than the racier look are:

• Lighter in weight
• Rotor rings are replaceable (cost less over the time than one piece)
• Can subject to extreme heat without cracking or warping due to our floating features

It’s car owners’ preference as to the fiction surface finish. If someone is into heavy tracking he usually would prefer to slotted only while for regular street driving and occasional light tracking our slotted and drilled rotors can satisfy both the look and performance. Note RB rotor materials are alloyed to increase the resistance to wear and cracking instead like others just fabricate from the stock blanks using regular material.

We know there are plenty of good pads out there but the performance of our rotors will be more enhanced with performance pads like Hawk which we have for our brake packages. HPS is most popular, well-performed and very little dust. We sold very few ceramic compound to someone very concerned on brake dust, but would not recommend for aggressive driving. HP+ is more aggressive and stops better than HPS but you have to put up with the dust and some squeaking noise during light stops.

Their is no problems to replace just the rear one for now and yes RB two piece OE caliper kits not only are track worthy, according to some of hard core racers they actually outperform some expensive aluminum caliper BBK costs thousands of dollars. – RB knows the fundamentals of a good brake system and builds them into our brakes accordingly. Our brakes can deliver stronger torque under extreme heat compared to competition, including the stock one piece rotors which we add our patented reinforced ribs to
G35 rotor, EVO rotor and others so our rotors will not warp like OE rotors or other manufacturers and always strong and stiff.
