Wilwood 270-12111D Starlite Wide Disc Brake Hub - 55-XD 5

The Wilwood Starlite 55-XD disc brake hub delivers exceptional strength and performance for demanding racing applications without the penalty of excessive weight. This advanced hub design represents a significant evolution of racing's most popular wide 5 hub pattern, weighing just over 7 pounds while providing superior structural integrity.

Key Features:

• Bolt-on rotor mount plate design eliminates brake torque loading from the main hub body
• Stress loads transferred to the thicker, stronger section near the inner wheel bearing for measurably reduced deflection
• Versatile rotor mounting configuration supports both fixed and dynamic mounting applications
• Dynamic mount t-nut bolt kits isolate thermal expansion stresses from dissimilar materials (iron rotor and aluminum mount)
• Black e-coat finish seals castings and preserves appearance
• Front hubs include Snap Cap dust covers for complete protection

What's Included:

• Hub assembly with rotor mount plate
• Mounting bolts for plate-to-hub attachment
• Snap Cap dust covers (front hubs only)

Note: Rear drive flanges, bolt-on dust caps for front conversion, and rotor bolt kits sold separately. The 55-XD's innovative design makes it ideal for circle track, road racing, and other high-performance applications where strength-to-weight ratio is critical.
