[Supras] stock brake rotors

[Walker, Brian (Rich. Dist)]

I'm no expert but honestly, I don't think there is a performance gain
from those type of rotors. Of course, with slots and drilling you are
increasing surface area slightly, which would mean they can shed a
little more heat. You're also decreasing contact area for the pad
slightly, which would mean a little less braking power (we're talking
very small amounts)
>From the research I've done, pads nowadays don't release a gas layer
like they used to which was the main reason for slotting/drilling, to
remove or scrap that layer away. When you have a drilled/slotted piece
(provided it's added after manufacturing vs. cast into the piece) you're
also adding areas prone to cracking. That's not going to be a big deal
for street use, most people use slotted/drilled for street because they
look cool. There are some processes out there like cryo treating that
are supposed to reduce the possibility of cracking, I've never tried
them though.
 
The performance improvement would be seen through better pads (more
torque to stop) and lines (more pedal effort applied to caliper).
Cooling and better fluid will combat problems that arise from heatsoak
like fade and dead pedal (boiling fluid).

Hi Brian,
     Those were very nice vids from your VIR track event.  I recall that
you are using a set of  aftermarket brake pads, but I wanted check if
you're still using the stock or an aftermarket, like slotted or cross
drilled.  Do you think there is more braking performance that can be
gained by switching to such aftermarket rotors?
 
Thanks in adance,
Khalid, 90 T
