I'll take a front set of these when they are ready .... great project Brandon.

moosejaw

as will I

gaiex

Looking for those for months!!!!!!!!

I'm on the market for a pair of floating rotors for the c32 brakes, when are you planing to start shipping it?

Me and my friends on the MB Portuguese forum are waiting for prices

Hjartarson

Sweet - I'll be sure to pick up 2 of these when mine need replacing

slowrey

I can't wait to buy em' and can't wait til you have all four available.

gaiex

I want to debate one subject with you guys,

I've been told that for our front brake system using lighter rotors won't be good, because of the power of the caliper, and thats why the stock rotors sucks!
I noticed another thing, brembo stock rotors replacement are also heavier than the OEM!!

So, lighter weight is better!? I always thinked so, but for this brake system now I'm confused, I was searching for lighter and better rotors from months...

PS: who told me that was an person who works in the brakes area...

moosejaw

I thought our rotors are brembo, like our calipers

gaiex

I don't think so, I'm betting on Lenförd ones.

I forgot to mention, ATE also have replacement rotors but they announce 345x30mm instead of 32!!! weight saving!?

e1000

see my reply above - #21.

gaiex

Can you explain me better whats the difference between true floating and the normal floating!?

e1000

There are 3 types of rotors, Full floating, partial floating, and single piece. Both Full floating and partial floating rotors use a 2piece design. This is good for two reasons. It allows for expansion of the outer disk area to prevent warping and it allows a lightweight aluminum hat for weight savings. The way the outer piece and inner hat are held together differentiates a full floating vs. partial floating. Partial (semi) floating rotors use a type of spring to hold the two together and the spring holds the disk in place in relation to the hat. Full floating rotors do not have this spring. For example, the rotors above are 2-piece full floating rotors. Brembo 2-piece floating rotors are partial floating.

One piece rotors are obviously the worst, they are heavy and are more likely to warp under extreme conditions.

e1000,

your reply to my post was an excellent explanation to my question. As I read it, gaiex is asking a completely different question "will going to a considerably lighter rotor somehow be a mismatch with the factory caliper?" - my guess is no, but I'm certainly no expert to answer it.

e1000

Honestly, I'm not quite sure what he was asking but I was hoping my answer above would clarify things for him. Lots of people have misconceptions about brakes and brake rotors. For example, Honda guys love getting cross drilled or slotted direct replacement rotors only to find out they warp very easily. This is because they're removing mass from an already small disk.

e1000

PICS!!!!!!!!!!!

Partial (Semi) Floating rotors - notice the spring mechanism:


The Code3 rotors above are a full-floating design and you can see how they do not have the spring.

redfarsi

what advantage does a 2 piece system have other then being cheaper to produce and being lighter? Could we expect these to come in drilled and slotted as well?

Thanks!

ps. great product!

gaiex

Why they put there a spring!? whats the function?
wasn't easier to put only screws...

c32AMG-DTM

Ummm... 2-piece rotors have several advantages, many of which have already been discussed... but "cheaper to produce" definitely ISN'T one of them - which is why they cost significantly more than 1-piece rotors.

For example, a set of stock OEM C32 1-piece front cross-drilled rotors can be purchased for about $240, give or take. These 2-piece C3P rotors are going to run somewhere around (i.e. under) $800 for a front set, according to Brandon. Which, incidentally, is a steal vs. upgrading to a BBK w/ 2-piece rotors.

Final point - if you read Brandon's first post, he clearly mentions that the picture is the prototype and the production rotors will be slotted, with a black (anodized, presumably) hat.

redfarsi

Yes I read the part about the black hat, but I obviously missed the point about the slotting. I guess I was wrong on this one. Thanks for taking the time to clarify it for me c32AMG-DTM.

Code3 Performance

Just an update. The rotors will be available in either slotted, or slotted/drilled. They are about 6 weeks out now.

e1000

nice! I just got new rotors put on.

BenzoAMGpower

very nice upgrade... I would have definately gone that route if I hadnt gotten my Stoptechs already!!

hooleyboy

I want them. are you running any kinds of real world tests on them? if so can we maybe see a video stop from 60-0 or something like that on a benz? Maybe see a video of how these rotors out preform OEM?

e1000

For a single stop you won't see any difference. The limiting factor for our brakes is the grip that the front tires can provide. The difference between these rotors and a 1 piece rotor is that under heavy use they won't warp as easily AND, due to lighter weight, ride comfort may improve.

c32AMG-DTM

+1

Just adding to this - removing rotating unsprung mass has all sorts of performance advantages, you theoretically should see shorter braking, quicker accelleration, and better directional changes (i.e. sharper handling). Physics is physics. If these are sufficient enough to be measurable differences from stock 1-piece, it'd have to be tested to see - but all those characteristics should get better, just like if you added a wheel/tire package that's lighter than stock.

steve_bris

are these available yet ?
