Default when is time to change the pads/rotors on the stoptech 332mm kit?

Pads thickness = ??? mm
Rotor thickness = ??? mm

Do you guys actually bust out the measure tape and measure it? or kind of just check it visually?

Default Matt at StopTech told me to change the rotors when they're below 30mm. But, I won't until they crack

more than just the surface cracks that they have now.

Pads are visual.

how many miles on your stoptech rotors and what driving style? :-)

Default Hee hee...it's pass first, then brake! :-P

I followed him into a turn at Mid Ohio (coming off the back straight at 110) and saw him fly right past my braking point...at which point I said to myself "HELL NO!".

Default BTW, unless you track your car, you might not want to use this advice.

His method is more or less fine if the rotors are constantly subjected to extreme heat cycling. When the rotors have had enough, he'll develop cracks that will extend out to the edge of the rotor.

For a street driven kit that doesn't see a lot of track use, you might not be able to use those stress cracks as a marker, since you may never develop them. You're probably better off just using stoptech's guidelines of 30mm or thereabouts.

What's the average mileage you can get out of the rotors and pads?

Default I use a caliper to measure rotor thickness but you are supposed to use a mic.

I will probably use them when they go below minimum thickness.
I think the brake pad compound has as much or more to do with rotor wear than driving style.

that's difficult to answer since it depends on use and pad choice.
