I still have the stock sport rotors & I'm at 6000 miles. What would be a good time to change to the slotted 2-piece rotors? The rotors are starting to look alittle faded, are the new rotors made outta a better material to make them keep their finish longer?

Pretty much all rotors are made from iron, and will fade and eventually rust to a greater or lesser degree. Plating helps but doesn't put it off for ever. You can get 50-100K miles out of your stock rotors if your not racing.

Some racing rotors are made from stainless steel but no street rotors are.

there hasn't been any update on this...hopefully someone develops a 2 piece rotor

They do, just you have to buy the calipers to go with them :tup:

So if I switched my rotors soon, how long should these new slotted ones last before needing to get replaced?

Also any brake pad suggestions? I don't plan on taking it to the track, something that doesn't make alot of noise when stopping & won't kick up alot of brake dust either.

Slotted rotors last about the same, the main difference is that they typically can't be resurfaced. They tend to groove less but are a little harder on pads.

I don't know much about the street pad options, I'm still using the stock pads for the street. I know EBC Red are known for low dust but I haven't seen anyone try them on the 370 yet.

Dang I didn't know rotors lasted that long, I thought you had to replace them at a certain number of miles. What do you mean by "can't be resurfaced"? I don't mind trying them (Ebc Red) as long as they are better then stock & are a good brand since I've never heard of them.

Best to get some street pad advice from someone that's tried them in these cars or a 350.

Rotors last a long time in street driving conditions. The only reason to replace them is if they warp, crack, or scour. You can get at least 1 resurfacing out of the stock rotors if necessary.

Resurfacing refers to removing the surface layer of metal from the face of the rotor using a brake lathe. This is only necessary if the rotors are scored (grooving).

EPIC REVIVAL:

I was at Z1 today to get my car tuned (302 whp) and one of the guys pointed to a 2-piece rotor sitting on the counter. YUP IT'S FINALLY HERE!!!!!!
He explained to me how the curved vanes are a better design than the DBA kangaroo paws for cooling and weight. And that replacements would cost in the 400's.
They are still working on 2 piece rears, since it's been difficult because our rears are so thin.
This is 6 lbs lighter than DBA, 2 lbs lighter than CZP. I think I'll be going for these next summer :) $650

Z1 2 Piece Akebono Front Rotors

Yep, I actually purchased these last night DarkJak. Waiting on them to come in now.

To tie in with what some others said the only company i know who does 2 piece rears for Sport breaks is Relentless Autosports but they require you to put a spacer in your rear caliper....that and i personally dont like the company.....but to be fair others have had great results.

I'm running the Racing Brake 2 piece rotors. Front and rear. ;)

http://www.the370z.com/suspension-br...o-testing.html

Is the price for the front set or per rotor?

Which set of rotors you talking about?

The new 2 piece rotors.

The Racing Brake fronts.

Two-piece rotor (Open Slot) - 370Z (Sport) FRONT 2009

The rears.

Two-piece rotor (Open Slot) - 370Z (Sport) REAR 09-11

Not cheap. But you get what you paid for. I would PM them for pricing though.

Yea I'm waiting on Z1's rear rotors.

Or you could pay less for the z1 rotors and get a quality item too.

I follow a lot of what Z1 does and know there's a lot of real track testing that is done.

Who manufactured the rotors?

The z1 rotors are not much lighter than stock.. Again you get what you pay for...

Seriously?? They are ten pounds lighter than stock, per rotor. Z1 has postponed these rotors for a year and a half to test and get the right metallurgy. Hell the basic rotors (one pc) hold up great. These are better. The RB are only eight pounds lighter. I believe my AP's are twelve pounds lighter. Soooo.

Z1 2 Piece Akebono Front Rotors

Oh snap, I must have read it wrong. Put me down for a set!!!!!!!! Any idea when this will be available? Any pics?

They look just my stoptech rotors. Will call z1 tomorrow to see if this are in stock..

The guy at the counter mentioned something about sharing the rotor with Stoptech. That's what made it a lot easier (our front rotor size is common)

He also noted that the hardware that holds the hat to the rotor is very tough too.

Correct me if Iam wrong but isn't most if not all of the weight savings in the center? I fully understand the weight savings of rotational mass but that's if its on the outer diameter not the inner..

were you the one at Z1 on saturday??

its true, but its still rotational mass and helps. Not many ways to save weight over there otherwise.

just to be anal, whats the weight difference of slotted vs slotted drilled?

Idk I'd say a good deal comes from the slotted rotors too which is outside.

Yes it is but also the amount of metal used is a lot less and the metal type used is lighter.
Hardly any. Stay away from crossed drilled rotors. The eventually get stress cracks around the holes.

Either way, its still unsprung weight, and that's the best kind of weight to take off the car

Calling z1 now and maybe they will hook me up since I know spohn...

Good luck. I always flirt with Jon (cause he leans that way, lol JK) but get no where.

Just got off the phone with jon and placed an order... Spohn I may have a female screen but I really worry about you sometimes...

Anything to get ahead. Lol. It's not the face you f@*k, but the f@*k you face. You can go a long ways on that. Bwahahaha.

Jon did say you were a Strange Breed.... lol

I have to agree.

Installed today. Great quality. http://img.tapatalk.com/d/13/08/23/jyqy9e7e.jpg

^^^ did you happen to weigh? Is it a true 10lbs per rotor?

Where did that info come from. It's more like 20lbs per rotor.

Also they posted on FB the rear 2pc rotors are being put to the test.
