two piece rotors vs one piece rotors

[skitz047]

i'm looking into a upgrading the brakes on my n/a.

was thinking about replacing the rotors/pads (probably greenstuff pads what do you think?) in front and maybe back. i got 91k miles on my car and as far as i know nothing has been done to the breaks. what do you guys think?

are the two piece rotors just a benefit so they cool down quicker or is it more complicated? should i got with the two piece rotors? also should i upgrade my calipers? thanks

Well, with a N/A, you don't need anything too big. I have greenstuff pads on my Z right now, and I will probably never get them again. They do stop pretty good, but they get really noisy after you do any hard braking. I will be getting Hawk HP pads next as I heard they are very good pads.

you'll be fine with one piece rotors. look into cross drilled and slotted brembo rotors for your car though.

two piece are merely lighter as they have aluminum hats. Not worth the extra money IMO, especially on an NA.

Okay thanks, but not this summer, but the next, i will be doing the tt swap. I can't do it this summer because i won't have the money, seeing as when i do it i want to drop amz turbos in it, new wriing harness, injectors, aluminum flywheel, racing clutch, ect...

2 piece rotors are intended for heavy duty track operations, IMO they are a waste of $$$ on a street car NA or boosted. They do have an uber bling factor but I suggest just getting cross drilled/slotted or both with some good pads and stainless lines all of which can be had for just about the price of a complete set of two piece rotors.

I only have to disagree with 2 things

NSR, crossdrilled AND slotted is bad, one or the other but not both. slotted is my preference but some people swear by divotted/crossdrilled.

ddg, they are usually much lighter than their 1 piece counterparts (brembo blanks) by quite a bit (~5lbs each), but agreed that unless you track, you probably can't justify it. Another bonus is the hats dont rust and the disc quality is usually a bit better.

I think the following brake kit is an awesome deal, and I plan on getting it when I have the money:

You have to have 17" wheels though. It uses the stock caliper, but upgrades the rotor to 13".

How do you figure its bad? Lots of people run both drilled and slotted on cars that are streetable and car that are tracked with no issue.

Also, if a rotor is zinc coated or if the hat is treated it won't rust. And how do you figure the disk quality is better on a two piece rotor? Just because the hat is aluminum on a two piece rotor doesn't make the face of the rotor itself any better. That's just silly.

Just wanted to add Ive never heard anything positive about EBC pads...

OLD WIVES TALE, I have been running cross drill/slotted, stainless lines and Hawk Pads for over a year now with no probs. WIth this setup I've gotten a serious decrease in stopping distances and extrememly less brake fade.

over rotors with neither maybe, but slotted by itself or crossdrilled by itself will yield more surface area (ie: more friction) with the same gas venting advantage of its slotted and crossdrilled counterpart without being weakened by all the added holes.

nsr - most of the 2-piece rotors are available in zinc, but not all of the 1 piece are (i'd say less than half).

[evildky]

nothing wrong with slot and drilled, it does not lessen breaking force, it does lessen rotating mass and improve offgasing, as far as measurable difference I don't see ti being substantial, but you increase surface are for heat disipation and that reduces fade, that would be the single largest benefit

I've always wondered about the statement "Well, with an N/A, it doesn't matter what size your <fill in the blank> is/are." Is there some wierd idea or data that a TT needs biger brakes, or tires, or seats, or wipers? Please. (You can't handle a corner any better than an N/A (with a good driver)) I know a TT will out-accelerate my car, but where did this idea that I can't hit a corner fast, or that I don't want traction, or nicer seats, or windshied wipers come from? I honestly don't get it!

Please. You TT guys have a forum just for TT guys. I "thought" that this forum was for folks with 300ZX'. Even us "lowly N/A" members want performance. If any TT owner can explain to me why you need better brakes than I do, I'd be happy to listen. Otherwise, please quit with the "well, since you have an N/A" statements.

I may, someday think, for some wierdly misunderstood reason, that I might, after considering all other more powerful options, decide that I would think that I want to install a TT, but it is really low on my list. Can't we just talk about performance without trying to devide into two groups?

Wow Ken....tell us how you really feel

Anyway, no need for the bit. Nobody is out to belittle you or hate on your NA. NA Z32's are fantastic cars and very capable. To touch on some of your points....

-Brakes : Generally the TT's are heavier than NA's and they have more power so bigger brakes is a good thing. Even Nissan themselves put bigger brakes on the TT's from the get go but later used the same brakes on all Z32's. Upgrading brakes on any Z is a good thing, but IMO not as necessary on an NA unless you track it on a regular basis.

-Tires : I don't see a lot of NA's making 400, 500, or 600hp so obviously those TT's that do could make good use of bigger tires. By all means, toss some 285's on an NA, nothing wrong with that, but they're not going to be very benefical.

-Seats : What do seats have to do with anything?

-Wipers : I hope this was tossed in for a laugh

All in all, like I said above, NA's are great cars. I've got absolutely nothing against them. For as long as I've had a Z32 (coming up on 7 years) I've forever heard the boasting of TT guys and the crying of NA guys. What can ya do? I bought a TT because I didn't want an NA. You may have bought an NA cause you wanted one or maybe because you wanted a vert and NA is your only option. IMO TT is the only way to go when serious power and performance goals are what you're after. To each their own though. The Z32 is a well balanced performance car regardless of powerplant.

NICO is a place for all Z people. Come hang out, share info, and be happy. No need for anybody to get all up tight or feel lowly.

[evildky]

personally unless you plan or using the car for some sort of competitive purpose no mods serve any purpose no matter what model, if you are going racing, be it hpde, club racing, autocross whatever the bigger brakes and tires are always a welcomed addtion to any car, but the stock brakes and the Z32 are pretty sweet out of the box, try driving a 240z sometime, the z32 brakes are freaking awesome

This rant left me confused. I have a N/A myself, so why would I be bashing on N/A guys? My comment was in no way to bash on N/A's (let me state again, I have a N/A), like nsrZ32 said, TT's weigh more and have the ability to gain more speed, which would be the need for bigger brakes. Take a straight-away and put a TT and a N/A on it with a corner at the end. The TT will be going much faster into the corner, and thus, needing more stopping power.

All this over rotors.....

I got one piece slotted and drilled, awesome stuff
