Well, I fucked up and i'm not able to do my Physics project in time for it's due-date, so i'm bullshitting it. My intention was to test aftermarket brake rotors vs. stock and see if the stopping distance changed significantly. All I need to know is if someone could tell me what (on average) the stopping distance was for an EG Civic Si. From 60mph to 0mph, how far did it take to come to a complete stop, is what i mean. I'm just gonna take that number and divide it in half, 'cause I was gonna do 30 - 0mph for safety reasons. I'd really appreciate the help, or even a link if you have one. I found the stopping distance for an EK using the search, but not an EG.

Don't know why you would do it on brake rotors, as they don't affect stopping distance, only thing they do is dissipate the heat from braking and slots also prevent pads from glazing.

Sssshhh! My physics teacher doesn't know that...

i'd have to say your fucked

i agree with marauder in saying that the rotors won't have nearly the effect that pads will have. You should just make up a bunch of falsified data and say how through your research you learned that pads affect breaking distance more than rotors. yaddayaddayadda, remember it is always the effort that counts, not whether or not you were right.

Why am I fucked? It's not like I have to prove rotors make a difference. It doesn't matter if my "hypothesis" is correct, just as long as I have the report and 'data'. My original intention was to test factory vs. aftermarket rotors, then for ***** and giggles test the new pads I got.

All I need is a number. 140ft, 150ft, I can't seem to find it anywhere

its not gonna be half the distance, itll be closer to like 1/3 or 1/4 of the distance, simple physics.

duh blacksheep

just right in your analysis and conclusion that rotors didnt make a difference, so you didint need the test for distances...whats the big deal? =P

Thanks, that helps

Well hows this...

Just change it up a little bit and say that standard rotors with glazed over pads stop worse than the same pads with slotted rotors. Since the slots keep the pad surface fresh.

I'd say the 30-0 mph braking distance is probably like 40 feet. Think you'll have a hard time finding it unless you do research for like car and driver magazine.

The four things that affect the brake system are:

1) line pressure
2) effective clamping radius
3) caliper piston area
4) friction coefficient (between rotor and pad)

I tried searching car and driver's website, as well as road and track, though I didn't get anything on the Si other than the '99/00 and the EP3. The list of things that affect the brake system really help

then just do it off of a 2000 or ep3, what does it matter, your bullshitting the evidence anyway?

Or just bullshit the entire thing.

Maybe i'll just use the EK data I found. Not a huge difference between an EK hatch and an EG hatch.

w00t, report is done. 7 pages (minimum of 5), including graphs and a couple pictures.

Is 40 feet too short? Should I bump up that number a little? Remember, this is 30 - 0mph
