• Orient the rotor (5) and the hat (6) as shown in Figure 1. Attach rotor to hat using bolts (7)
and washers (8). Using an alternating sequence, apply red Loctite
®
271 to the threads, and
torque to 155 in-lbs. For an added measure of security, the bolts may be safety wired using
standard 0.032 inch diameter stainless steel safety wire as shown in Figure 3. Please refer
to Wilwood’s data sheet DS-386 (available at
www.wilwood.com/Pdf/DataSheets/ds386.pdf
)
for complete safety wire installation instructions.
•Slide the rotor registration adapter (9) onto the axle register on the axle flange with the
smaller O.D. facing toward the hat/rotor (5/6). Slide the hat/rotor assembly onto the axle
hub. NOTE: The hat must fit flush against the axle hub flange or excessive rotor run out
may result. Install three lug nuts (finger tight) to keep the rotor in place while continuing with
the installation.
•Mount the caliper (Shelby supplied) onto the caliper mounting bracket (1) using bolts (10) as
shown in Figure 1. Torque caliper mounting bolts to 70 ft-lb.
•NOTE: For best performance and service life, Wilwood recommends using new brake pads with new replacement rotors.
• Remove the lug nuts that were holding the rotor in place. Install the wheel and torque the lug nuts to the manufacturer’s specification.
Ensure that the wheel rotates freely without any interference.
BEGIN BY SLIDING THE 0.032"

SHOWN (BELOW) USING SAFETY
WIRE PLIERS. NOW SLIDE ONE
WIRE THROUGH TWO OF THE
HOLES (180° APART) AND WRAP THE
OTHER WIRE AROUND THE BOLT.
TWIST THE WIRES TOGETHER TO
