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.
Our 4-wheel kit features a 2-piece 345mm front drilled and floating rotor with 6-piston
caliper and rear 328mm drilled and floating rotor with 4-piston caliper.
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 these vehicles:
2001-2006 E46 M3 (Including Competition Package)
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 radial mounting, differential
piston bores, 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 billet or forged 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.
The 6-piston variant has the same "hydraulic footprint" (meaning pedal
effort is the same), but has a unique six-piston differential bore configuration
provides balanced loading for even pad wear in sustained high heat
environments.
All variants 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.
