braking
#26
In an effort to answer the original poster's question:
Changing your pads, rotor, and lines will not significantly reduce your 60-0 distance. Stopping is a mostly a function of tires and weight. In other words, better brakes are good, but if you are using the same tires, they will still break traction at the same point, and it will result in about the same stopping distance.
However, what it WILL do is result in better consistancy. You can continually heat cycle the brakes, and they will continue to operate and stop in the same distance they did before. Whereas the stockers will eventually start to fade (which results in very difficult stopping). So in other words, upgrading brakes is by no means a bad idea. It'll give you much better consistancy and feel to your stopping ability.
Hope that helps,
Rob

Also, in reference to your comment about the use of slotted rotors: usually, the only racers that use them are the short-heat runners (less than 50 miles). They also change them after EVERY track event, as they are usually unsuable after that amount of time. Just a little FYI.

OK, below is the real world results of a 3200 lb '67 Camaro that had already been treated to Global West Suspension upgrades and 17" forged rollers. It had factory drums which were ditched for aftermarket Baer binders, front first and then they came back for the rears later which is where this comes from...
Next, is a Miata for weight comparison's sake...
"These are powerful brakes, firm and reassuring, with stops from 70 mph in 168 feet, bettering the last test Miata by 13 feet."

Okay, here we go. This is page 7-1 from my 85 RX-7 Owners manual. It clearly shows the stopping distance for a normally operating GSL-SE is somewhere between 145 and 150ft, depending on loading conditions.

Article, not owner's manual which is best wishes scenario, not real world....or are we to believe that the owners of the first RX-8s really do have 247 HP as their OWNER'S manuals clearly tells them? Do you see the fallacy of believing the owner's manual now?
Article, please...
You, too, schwarzer ritter....

Again, I advise you sir, to do some research to increase your knowledge base on certain subjects before spreading misinformation.

So now, we have to figure out who's telling the truth...Motor Trend or Car and Driver...
I know what I read...I used to get all the car mags, but dropped Automobile, Hot Rod, Motor Trend, and EuroCar because they were less than legit and more driven by who pays the bills. Automobile wasn't really like that, but it was too elitist for me to stomache. I've never dropped C&D or CarCraft for these same reasons. The stuff they do works in the real world and they are hardly discredited. I'm going with Car & Driver, thanks anyway....

60-0 is the normal comparison used for braking. Pay attention to the methods and test conditions, not just the results....
