STILLEN 1-piece Sport Rotors are a great choice
for performance, durability and style when staying with OE factory
calipers. These high-performance upgrades directly replace those
plain OE factory rotors with no modification required. Applications
for cars are finished with a tough clear zinc plating for
exceptional corrosion resistance and to avoid the pad contamination
and environmental issues with cadmium plating. Most truck and SUV
applications have a tough, black e-coat to keep the elements at
Why cross-drilled or slotted (or both)?
Cross-drilled rotors are a quick and simple way to improve initial
pad bite. With the additional leading edges at each hole, the pad
is able to grab the rotor just a little bit harder when it's time
to stop NOW! Tests have shown (and drivers can feel) the immediate
improvement. The holes also provide better cooling under hard use.
Pad wear may be accelerated slightly (depending on driving
technique), so only high quality brake pads should be considered.
Cross-drilled rotors are not recommended for serious track duty -
choose Slotted or Hook Slot rotors (when available) instead for
elevated temperature use.
But I've read that cross-drilled rotors are prone
to? While there is often some strand of truth in the
various tales circulating around the Internet, we have found that
many issues related to premature cracking or irregular pad wear are
due to rotors made of inferior materials, substandard manufacturing
techniques, poor pattern design or improper use. With over two
decades of experience in high-performance brake upgrades, STILLEN
has proven that high-quality, well-made cross-drilled rotors are a
worthy upgrade for high-performance driving duty short of serious
What makes are STILLEN Sport Rotors
different? High-quality, 1-piece blanks are sourced
from the world's best foundries. Each application is carefully
scrutinized for the optimum face pattern, whether cross-drilled,
slotted, cross-drilled and Slotted or Hook Slot. The latest CAD
(Computer-Aided Design) tools are used to optimize the face pattern
for full pad sweep to reduce hot spots and grooving.
All cross-drilled holes are radius-chamfered with special tooling
to minimize stress-raisers for maximum resistance to heat and
longer rotor life compared to lower-priced offerings. Slots are
ramped to reduce pad dust retention and noise. STILLEN Sport Rotors
arrive finished, machine-balanced and ready to install!
I spent a lot on custom wheels. What will these rotors look
like months from now? Sport Rotors for most car
applications are zinc plated for corrosion resistance, which keeps
them looking good and rust-free in most environments. Truck/SUV
applications are typically black E-coated for a tough,
OK, I'm ready to upgrade. What next? Enhance a
new set of Sport Rotors with STILLEN Metal Matrix brake pads or
choose from other performance pad options. For the complete
package, choose stainless steel braided brake lines and fresh AP
Racing brake fluid for a more positive brake pedal feel and
resistance to fluid boiling. Remember, car manufacturers recommend
a brake system flush at no longer than 24 month intervals, shorter
for hard brake use. If it has been too long, upgrading brake lines
at the same time will save time and labor.
