treyZ28: I have done a little research on you and I have come to the conclusion that you have contributed nothing to this site. Go back and search every one of your post and all I can find is multiple post of you either **** talking or putting down other members. Obviously there is not a sole here that will be able to compete with your knowledge of brakes, motors, shocks, or driving ability. I challenge you to become a positive person and contribute information in a non-abrasive matter. This may yield you the attitude and respect that you seem to be looking for. Stop feeding us with your number dropping and fact quoting, and possibly there would not be so much hostility toward you.

I am sure you will come up with some smart *** reply to this post as I have seen you do with every post here. Don't waste your time, I don't care to read your crap anymore. Once you can post valuable info without the attitude please feel free to e-mail me, I would love to hear what you have to say. There seems to be some good info in that BIG head of yours, I think it may behoove of you to learn a better delivery method.

Thanks,
B

 

Ok, let me make Macadayear's question very clear since you obviously love to correct his English spelling and grammar, then go on about stuff irrelevant to the topic. No wonder you got fired from that brake company, you were obviously very good at it. We're supposed to believe you?

That is the driver side front rotor. What he meant when he said he thought he put it on backwards was his referring to the way the hole and slot pattern go. If you took this rotor and put it on the passenger side, the holes and slots would be going the other way, right? That's what he was asking. Is that clear enough for you?

If I had to guess, you came from ls1.com, have a 12 inch ****, can bench 400 pounds and are dating Heidi Klum.
Oh yea, you probably look like this too,

 

oh and one more thing:

 

I think this is ready to come out ---> and





Oh yeah and ...

 

Naa, just make sure you use proper English and spell every word correctly, you know, like he does
He has good information I suppose. I mean, he worked at a brake company and got fired Hmm, why aren't the real pros posting on here? We just get the crap riff raff to come on here and SAY (key word here) that they've worked for an 11 billion dollar company and everything they say is gospel. Believe who/what you want.

 

 

i got in this one late but id like to say that stock rotors are the ****.

 

ok. This thread was not meant to be like the last one, but it has gone that way. I have a challenge for you guys. Throw information out saying that cd-ed and slotted rotors DO make a difference. I don't want your opinions like you have been giving me the whole time. I can "feel" it..Show me some solid information that shows cd-ed rotors actually help on a daily driver. I know i haven't thrown numbers out myself, but i have gievn you results of test i personally have ran and those of my co-workers. i am trying to give you what i have found without being completely biased. yea the slotted rotors will cool some, i will agree to that as i have before, but you loose braking surface. The only way to actually say that these help performance is being able to show that the effects of the amount of heat dissipated are greater than that of the amount of braking surface lost. agreed?

Like i have said previously the only true way to get much better braking performance is to go the overly expensive route and get better(bigger) calipers, bigger rotors, and bigger, better pads, and steel braided brake lines. The more braking surface area you have the faster the truck will stop. that is a univeral truth.

 

Of coarse, lets not listen to logic, test data, and physics. We’ll throw that all out the window in favor of “yO! I got these bad *** rotors and they cut holes in the for me and now I stop better. I don’t really know, but I went down this hill and I think I stopped faster.”

You tell me to go shove my facts, research, physics, so on and so forth. You refuse to believe testing conducted by massive companies that do almost nothing but make brakes; and their chief engineer at that. You wont listen to the companies that actually sell you the cross drilled rotors and say “hey, these will **** your **** up but they look bling.”

Go look at any of the hardcore autocross guys. Think there is reason they don’t use it? Think there is a reason why baer and wilwood say on their website they DON’T cool and actually heat up rotors? But we wont listen to them, this guy drove down a REALLY BIG HILL.

And my being fired (wasn’t even actually fired) had nothing to do with my performance; make no mistake about that. Nor is it any of your businessJ. Couldn’t have been that bad; Roush hired me a few weeks laterJ. Not that big of a deal at my school though. We have guys on w/ Chevy’s Indy car and NASCAR (few, but in a school of 1500, its enough). I’m a retard compared to some of the guys at my school. Simply incredible some of the talent some guys have.

When it comes to brakes I assure you I know what I’m talking about. I didn’t come here to make up stuff about rotors and pay off major braking companies to back me. Just step back a minute and look at it. Maybe *gasp* it is an internet myth! The amazing thing is you want me to STOP using facts and data. You would rather just believe some shade-tree mechanic that resells parts with an “everyone knows that” comment. I guess its just natural to leg-hump a vendor at any given opportunity.

Beyond physics and thermo and testing; it’s more logical than anything else. Less metal to soak up heat. Less surface area for the air is actually flowing. Saying that a significant amount of air flows through those holes is like saying you should side mount a radiator to your door.

Let me try one more time. Looking at the side of the car; up and down is “Y” direction; left and right is “X” direction. Into and out of the page (or through the car) is “Z.” Air is flowing in the X,Y plane. Across the car and because of the vents inside the rotor, up and down as well (vents spinning in a circle “shoot” in all directions on the XY plane.) There is almost no air going sideways through the car. Air does not want to make right hand turns. It has no momentum or velocity in that direction (aside from a bit or turbulence and cross wind). That is why you want to maximize the surface area where the air is flowing (again, think why a side-mount radiator would be dumb). The only place I can see cross drilling being effective is on open wheel things like a bike. Bikes are really too light to have heat fade in the rotors though with such an exposed rotor. They are better off lightening the rotors. Fade will probably come from brake fluid overheating.

I have no idea where the shocks or driving ability thing comes from; I never did any suspension research and I’m a mediocre driver on my best day. Never been to LS1.com; average **** and I’d probably be lucky to bench 175 right now.

Now some of you still don’t “see it.” There is a lot of stuff that would surprise you, just yesterday we got some test data that seemed flat out wrong and beyond anything anyone here would have guessed. But that’s why we do wind tunnel testing, our intuitions can be wrong.


Nick: as far as the cooling thing; as you stated its either worse or a completely negligable gain at best. I've heard both schools of thought. Stimpson and Jason (TRW) said negligable. A few other guys in the group back in the day said hurt. I'm still following hurt but I think it depends on wheel, underbody and overall vehicle disign as to how it is routing the air. Some wheels might draw in air while others are very enclosed/wide.

 

to me you can brake this and that.i like this picture.to me it sais a lot by itself.oh yay this is on a 200mph nascar.
