Incorporating the real-world needs
of racers
and street car enthusiasts, UUC's "rationalized" brake package
that uses premium Wilwood Engineering components for better braking,
lighter
weight, and idealized front/rear brake bias, all in an affordable
package with
the largest offering of performance street and race pads available.
This rear add-on is designed for perfect bias with the UUC Stage2 Front
kit for
the 2001-2006 E46 330i/Ci
Configurations:
4-piston with 1-piece vented and slotted rotors.
Standard caliper color is black with optional red calipers. All kits include stainless steel
brake lines, street performance pads, and all brackets and hardware
required for installation.
This kit part number fits the rear of these vehicles:
2001-2005 E46 330i/Ci, 328i/Ci, 325i/Ci, 323i/Ci (includes all 4-door,
2-door, Touring, and Convertible models)
From its inception in 1977, Wilwood
Engineering has been at the forefront of high performance disc
brake
technology. Wilwood calipers are found in virtually every professional
and
motorsports arena, and often found in the winner's circle.
Wilwood incorporates a variety of innovative and time proven
performance
enhancements in its caliper designs. They include high temperature
seals, SRS
Squeal Reduction and bridge reinforcement plates, internal heat
shields, quick
access pad retention, shock dampened fluid tubes, and center bridge
bolts
(features vary by model).
The Superlite series of Wilwood calipers integrates
"Big Brake" style and Wilwood's latest technology. Each caliper is
precision CNC machined from high strength orged aluminum. The key to
the
superior performance of the Superlite
caliper comes from the
extremely durable,
efficient and lightweight body design.
At
about 4lbs 10oz., it is the product of computer generated solid
modeling and FEA
stress analysis technology. Full
length
stiffening ribs and a reinforced radial transition from the piston bore
housings
to the closed end bridges have
produced the
strongest Superlite caliper bodies ever built. When compared to open
bridge
calipers that use tube or stand spacers
between the
body halves, the closed end bridge design is measurably stronger
with less separation or deflection under load. Additional strength and
resistance to deflection comes from the
four
high-strength steel end bridge bolts. A fifth center bridge bolt
provides even
more overall strength and easy access
to the
pads without the need to remove the caliper from the mount.
The
4-piston
variant of the Superlite is legal for various SCCA and BMW CCA classes
that
limit piston count.
This caliper feature pistons made from stainless steel pistons, used
for its
slow heat transfer properties and high
resistance to
corrosion. Cooler temperatures translate to longer service life and
less
chance for heat induced pedal fade.
In
addition, each
Superlite is equipped with SRS bridge plates. SRS plates eliminate all
bridge
wear caused by pad gouging and
extend the
service life of the caliper. The spring-loaded action of the SRS plates
also
eliminates pad rattle and dampens
the
harmonic vibrations that contribute to pad squeal. Two piece bleed
screws and
dampened fluid tubes are recess
mounted to
shield them from track debris and other potential damage sources. High
temperature,
square faced bore seals provide the largest possible sealing area and
controlled
piston retraction on release. The
full range
of Wilwood pad compounds is available to match the brake response and
heat range
of any competition or sports
driving
application.
