On the WRX, there is no need for the slotted rotors. The OEM brakes size can
easily stop the vehicle with just the plain Brembo vented rotors and some
racing brake pads. For cars with ample braking size, I would always opted
for the carbon or Kevlar brake pads. It is in the pads (not to forget- add
some front steel braided lines for high pressure), for those who like to
stop at the last second, will suffice car braking.
Most Jap rice burners vehicles really don't need any slotted rotors or
drilled out types. Maybe for cosmetic or taste but functionality, you just
wasted your money. Even while racing in the SOLO CLASS II, I use the carbon
type from EBC (Greenstuffs) and they are great for fast stopping power on
regular vented rotors. You are looking at the vehicle body weight and
driver's driving habits that makes the determination of which way to go in
replacing the brakes.
Now with heavier vehicles (Dakotas, Astro, Rams...), utilizing car brakes on
truck frame vehicles, known by GM buyers as cutting corners on production,
you will need to opt for vented and either slotted or drilled type rotors.
Also, you will need to ensure that the brakes pads are the dustless version
with low wear rate and can accept high-temps while trying to stop in the
beast in a worst-case scenario. For towing I would opt for this version that
is cheaper on the wallet.
If you have the money then you should go to four or a six-caliper type
braking system. It is very expensive but at least it will stop quickly
under extreme loads.

"Democracy cannot exist as a permanent form of government.
It can only exist until voters discover they can vote themselves
largess (generous gifts) from the public treasury. From that moment
on, the majority always votes for the candidates promising the most
benefits from the public treasury, with the result that a democracy
always collapses over loose fiscal policy, always followed by a
dictatorship. The average age of the world's greatest civilizations
has been 200 years. These nations have progressed through this
sequence: from spiritual faith to great courage; from courage to
liberty; from liberty to abundance; from abundance to complacency;
from complacency to apathy; from apathy to dependence; from
dependence back again to bondage.

Hello Daker's!
I know the majority of us enjoy the Powerslot/Raybestos combination for
braking. I had a few questions for y'all ;) (please excuse my wannabe
Southerner expression - my Aunt/Uncle live in NC, so it keeps coming into my
vocab) My standard driving is 80% highway/10% city/10% country. 5 times /
year I pull our pop-up camper (approx 2,500lbs). Hoping to have a floatation
device to pull of 5,500lbs ;^P
1) For those that have made the switch to the above combo, have you noticed
an increase in pad usage with the slotted rotors compared to the OEM's? How
often do you change your pads now as compared to before?
2) As an alternative to the powerslots, have any of you considered going to
a 4-piston caliper? This way the pad will be gripping on both ends of the
pad. I'm curious to know with the non-slotted rotors if this will benefit
the stopping distance as much as the slotted rotors will.
3) Does anyone make a larger rotor and caliper combo to fit inside our 16X8
rims? These stock OEM rotors are tiny compared to what could fit inside.
I know doing any of these will help in minimizing the stopping distance, I'm
just trying to get the best bang for the buck. The 4-piston idea came up
talking with a fellow engineer that put them on his WRX that he races on
road courses. Of course he installed the powerslots as well. He has noticed
a fair increase in wear in pads with his ride. I thought I'd ask about our
vehicles compared to an AWD car to compare.
FYI, I won't be able to respond until Monday, but I'll post the summary when
I return. I'm shuttering now in my '01 and need to get this corrected.
Thanks for your help guys and gals! Have a great weekend!
