Sport Brake Rotors
Cross Drilled & Slotted
Brakes are the one area of performance modifications that are
often misunderstood. Some think the OEM stock is fine,
some think that BBKs are a must, and there are probably a dozen or
so opinions about x-drilled and/or slotted rotors. Lets set the
record straight once and for all. Start with what you have, and if
that currently works for you, keep it. When its time for you to
upgrade the performance of your car and step up your driving style,
then maybe its time to upgrade your brakes as well. This is where
we step in. Here at PWJDM all of our products are well thought out,
we dont just go off on a tangent and do things. We actually do sit
down and calculate things out before our moves are made. Our latest
and greatest for the month the Password JDM
Performance Brake Rotors are no different 100% drilled, slotted,
and zinc plated here in the USA with quality control
at every level thats common with all PWJDM
products.
PWJDM Performance Brake Rotors are well thought
out. Each design is first proven on a 3D CAD system
and then modeled to fit the vane pattern unique to each rotor
application. Our goal has always been to improve performance
without sacrificing quality. PWJDM starts off by
sourcing blank rotors from the best foundries. We offer our rotors
in 2 distinct designs. The first design is a X-drilled/slotted
rotor thats perfect for moderate to aggressive street use. The
second design is a dimple drilled/slotted designed for track use.
What makes our rotors different from the competition is that we
perform all the slotting/drilling in house on our 3axis
HAAS CNC machines using only American
Made Carbide tooling for precision thats unmatched by the
competition. Each individual hole is also chamfered on the
CNC machines as well. This does cost us a bit more,
but the cost is also offset by the fact that everything is done in
house other than sourcing the blank rotors from the best foundries.
Once drilled and slotted, each rotor is then individually zinc
plated within a few hours to protect all raw surfaces against
corrosion. Finding a rotor of this quality will probably cost you
twice to three times as much with the competition.
X-drilled/slotted rotors offer the best of both worlds in terms
of street performance. X-drilling greatly improves brake response
by giving pads the ability to quickly outgas and cool off during
pad contact. The slots acts like wipers clearing the pad face and
eliminating the glaze created by pad friction during contact. We
found that this combination although a bit more expensive to
produce, actually works best in most application. Use of these
rotors has shown to greatly increase brake performance and pad life
as a result of the additional cooling from x-drilling. We calculate
the number of x-drills and slots based on the size of the rotor,
the number of vanes and the application to optimize performance. We
think its counterproductive to just drill as many holes in a rotor
and calling it a performance item that something the competition
would do.
Dimple Drilled/Slotted Rotors offers the best of both worlds in
terms of track performance. Dimple Drilling allows the rotors to
outgas during contact without too much cooling. When on the track,
what you want from a rotor is one thats stable in temperature
without the excessive heat cycling that will crack rotors over
time. This design has proven itself time and again to get the job
done and increase brake performance and still keeping the pad temps
within an optimal heat range for the best in brake performance. The
slots acts like wipers clearing the pad face and eliminating the
glaze created by pad friction during contact. Through our extensive
testing, Dimple drilling and slotting outperforms all other designs
for track use. This is the best solution
As you can see, not all performance 1pc rotors are equal.
PWJDM has taken the time to research and design a
better rotor option. Our time as been well spent so you can have
the best rotors on the market at a price thats reasonable. These
are definitely the best bang for your buck in these trying times.
Buy a set today and start I meant stop as soon as possible. Better
brakes should definitely be high on your list of mods to do. When
the time comes, remember that PWJDM products are that
much better than the competition all because we design and produce
each product in house so you can have the best.
