Rotor Discussion
 

I wanna replace my rotors and brake pads, ive heard some things about slotted rotors vs regular rotors saying slotted is no good cause u need more to dissipate heat. I need to order today, could I get some recommendations and advise?

Ah hah! I knew it, mods... please and ty

Best bang for your buck:
Z1 2 Piece Akebono Front Rotors

The slots on the rotor are to remove gas build up that is generated under heavy braking.

HowStuffWorks "Drilled Brake Rotors"

You can run with drilled and slotted just fine if you don't drive at 10/10th's all the time. If you track regularly then you should spring for slotted only.

Gbret, I dont Regret knowing u ! See what I did there

For what it's worth... I have the Z1 Drilled and Slotted front rotors and have noticed slight a performance increase with them, less rotational mass.

I also tortured them on US129 (the dragon) @ Zdayz and had zero issues with warping.

It's cracking that you want to look out for with drilled rotors.

I've used drilled rotors for years and never had an issue with drilled rotors. I have only seen that issue if someone was pulling a heavy load with a diesel truck had drilled rotors. In that case, I would opt for standard rotors and add an exhaust brake.

So if I get new rotors I need new pads as well. Any recommendations

So the z1 is on the lower end on pricing but on the higher end of performance right? Also should I just opt for new oem pads, imo they r really good

The link showed you was for two piece rotors. They are more expensive then solid rotors because they are lighter. On the flipside, they are cheaper than other two piece rotors.

If you don't care about increasing your car's performance you should get these:
Z1 370Z / G37 (Sport) Performance Rotors - Akebono

If you are looking to gain performance then spring for the two piece rotors. The reason for the gained performance is because you are reducing rotational mass. If that makes no sense to you... do some reading:
Rotating Mass, Available Horsepower, and Acceleration

Soo should I get all four rotors?

$600 for a set of front rotors? Maybe if you race competitively but even then… My Z is a track only machine and I would never spend that much on rotors.

If you are worried about rotor life why not just buy 5 sets of Centric rotors from Rock Auto. The price will be the same.

If you are in it for looks, then definitely go for the drilled, slotted, 2 piece rotors because they really do look good. I have no problem if that is your motivation.

But if all you are looking for is the best rotors then you need to understand what a rotor does. It is just a heat sink. The more metal the better. And of course, holes and slots remove metal. I suggest that you shop around and pay attention to the rotor weight. Try and find the heaviest rotor in your price range.

I have no idea on the life of your current rotors. I was only helping with the original question. Maybe you don't even need to worry about spending money on rotors. You can have your old rotors turned on a lathe if they have lots of metal left.

Front brakes are about 75% of your stopping power so I don't think you can go wrong spending money there.

The Z1 rotors are meaty so it works well as a heat sync and they stay cool due to the cooling veins. They are on the pricey side but they are good value compared to other two piece rotors:
(The DBA rotors are super nice btw.)

Trust me, less rotational mass is a good thing. You can accelerate quicker, stop quicker and turn in feels better. It's a win all the way around... except on price.

Again, if Minsu doesn't care about the additional performance then he should spring for a 1 piece rotor.

theres also the slotted versions. EBC has some, i ran them previously on my 350z.

I've seen it often. Here is a recent one I saw at a local car show on a gt3 rs

I agree with everything you are saying. Reducing rotor weight (i.e. rotational mass) will improve performance. And if money is not an issue they are an absolute no brainer.

And for what it is worth, they really are beautiful pieces!

I run Z1's 1 piece slotted rotors. They weight about the same as stock and have super-cool slots in them. No point in buying 2 piece rotors unless you are doing some serious tracking. Stay away from cross drilled rotors.

I've had my Z1s on the track a few times and they do great. They are also cheap.

Why are you replacing your rotors? Unless you're really driving your car spiritedly I think just replacing pads will be fine for you.

I have stuttering while braking from.high speeds

Oh no, the warped rotor debate!

Step 1:
Buy new front pads. Research your needs:

Step 2:
a.) Buy your self a new set of rotors.

OR
b.) Have a mechanic turn your current rotors if they have a lot of metal left.

Step 3:
Have a mechanic install your pads/rotors. I'm not so sure turning wrenches are your strong point.

You may also want to have your brake fluid flushed on your car if it has been 3 years.

Andrew / Depoint50 is a dealer with plenty of knowledge. Send him a PM.


My spoon feeder just broke so you will need to search from here on out.

Troll?

Gbrettin, sorry I lost track of this thread, I forgot to say Thank You for helping me so much, im usually good with it but I completely forgot due to alot of things going on. I think ill go with the Z1 one piece slotted rotors and see if I can get a set of OEM brake pads. I think it will be quicker just to bring everything to the shop and have them replace everything, its my DD and only car so I cant really wait to long. Thanks for all your help, its being put to good use!

Z1 370Z / G37 (Sport) Performance Rotors - Akebono

Im going to get these SLOTTED.
Do i only get the fronts or should i get all four.
Should I just get all four and all OEM brake pads.
Do these even fit on the back wheels?

There are two different sizes when you buy all four. Larger on the front:tiphat:

so if i just put quantity to 4 would they know to send me two diff sizes?

There's the option to buy all four. Of course they know lol. If you are still confused... Order over the phone

In your spare time read this: Car Bibles : The Brake Bible
For reference it's 180 for 2 front oem rotors.

Drilled, slotted, or drilled and slotted will have no worth while benefit for street driving. They a number of negatives to them, one being a tendency to wear pads faster and any heat issues would be better resolved from by other methods (better pads, fluids, brake ducts, etc).

No problem. Happy I could help.

And yes, the fronts are very different from the back rotors.

Although... it would be wild to see some front rotors installed on the back and turn up the stopping power.

For reference, here is what the front and rear rotors look like up close installed:

Front:

Rear:
http://www.the370z.com/attachment.ph...1&d=1409168216

^ Those (FRONT) are 2 piece slotted and drilled, which is not what he ordered. I dont' see the need in getting new rear brake rotors at this time Minsu. The vibration is coming from the front ones.

I'm happy with my Z1 OEM style rotors, although they have a stupid black coating on the center hat that just turned into liquid goo at the track when they got hot.

What pads did you used?

Front - Carbotech 1521
Rear - EBC Yellow

It looks like you're using spacers (with new bolts) on the rear. I could use some myself to push out my XXR rims as the offsets do no match factory specs so the rear tires are a bit too far in. Any suggestions for spaces?
