I've been working at PFC for a while now. well it's finality time I gave the wife's car a little TLC
 |
| Got her 350z roadster up in the air. |
 |
About 75k miles ago, I sourced my rotors from
FrozenRotors.com. These little bad boys lasted me a while!
|
 |
| I pulled the pins out of the Brembo caliper. This
will release the pads |
 |
To compress
the caliper pistons I grip the top of the pads and squeeze. The pad will push
the pistons back into the caliper, while using the rotor as a leaver. After this the pads are toast, but I knew
that going into this project.
|
 |
After that I pulled
the pads and unbolted the caliper. I placed the rotor on the ground to compare
it to the new 2 piece rotors.
|
 |
You can see
the directional veins. This feature increase air speed flowing out of the
rotor, keeping it cooler.
|
 |
| The cheaper way of making a rotor is not have non directional or straight veins. This means the rotor was built to a price, and not to be built as good as it could be. Having directional veins is a mark of a purpose built rotor. |
 |
By now you
have also noticed the 2 piece design. The aluminum hat and iron rotor is dome
for numerous reasons. Excuse me while I go full nerd!
|
 |
| Weight: This combo will save 5lbs per corner. Rotational
energy is the hardest to stop. Saving 5 lbs will help stopping distances. Ride quality and grip will increase. |
 |
Prevent rotor coning/drag.
When a rotor gets hot it will grow, this is called thermal expansion. When a rotor gets really hot it will reach the outer limits of outward thermal expansion. After it can't grow outwards anymore it will begin to bend or what people in the brake industry call “cone”. It will bend towards the hottest side. |
 |
"Coning” creates allot of drag, this ruins pads, kills
rotors, destroys top speed, and shells mpg. It’s all around a bad thing to deal
with.
|
Sorry, I was on a rant for a min
 |
Back to the install! It is incredibly important to clean
your hubs. A little raised will create allot of kick back, and could ruin your
new rotors.
|
 |
I grabbed a sanding block and went to town. I’m not trying
to buff it to a shine. I’m just trying to removing any high spots and rust.
|
 |
| Shiny! |
 |
| New set of 01 race pads! 0960.01.17.44 the part # for a 350z |
 |
| Slid the new guys in ,and re-installed the calipers. |
