Mini Sprint Front Rotor
and Brake Combo
This ultimate lightweight Mini-Sprint front brake combination includes a precision CNC-machined aluminum front brake rotor specifically designed Keizer hubs with 5 x 2.38" mount circle. The rotor is heat-treated, anodized, drilled, and scalloped, the full symmetrical machining provides perfect balance and flatness. The lightweight two-piston (1.25" diameter) caliper, for
use with .25" wide rotors, weighs only .90 pounds. Designed for tight fit applications while utilizing a standard 2.38" mounting. The composite metallic compound “Purple Pads” are ideal for high-temperature durabili- ty on aluminum brake rotors.

The most effective method of eliminating thermal stress and distortion, dynamic-mounted rotors are machined to accept special bolts and T-nuts, allowing the rotor to expand and contract independently of the mounting hub or hat.
Superior heat absorption and dissipation make GT-36/GT-48 rotors ideal for professional motorsports. Cast from premium carbon iron for thermal stability, resistance to distortion, and extended life.

UL-32 Straight Vane Rotors
Ultralight rotors are the popular choice for dirt track and lighter duty pavement racing. Premi- um-grade, long-grain carbon iron provides excel- lent thermal stability, long life, and resistance to heat checking. UL-32 rotors include straight vanes for improved cooling.

UL-36 Curved Vane Rotors
WIL160-12292
3-hole mount aluminum rotors are precision
CNC-machined from high-strength billet plate.
Full symmetrical machining provides perfect bal-
ance and flatness, and the truest rotation of any
rotor being built. These rotors fit the popular 3 x
5.00" bolt circle found on most sprint and midget
front hubs. A durable black anodized finish
prevents corrosion and simplifies the visual inspection of the contact faces. The best results are always achieved using Wilwood "Purple" brake pads.
Manufactured from a proprietary iron alloy de- veloped to withstand extreme temperatures with
the highest possible degree of resistance against distortion, warping, cracking, and wear. This alloy
is a derivative of the technology and materials developed by Wilwood for extreme-duty military
spec rotors. Every Spec 37 rotor is machined to
less than .001" run-out, flatness, and parallelism. Combined with our proven GT Series asymmetri-
cal face slot pattern and individual dynamic balancing.
