Wilwood 120-9693-SI DynaPro Forged Billet Brake Caliper Lug Mount - 5.25

The Wilwood DynaPro Lug Mount forged billet caliper delivers championship-proven stopping power with cutting-edge engineering designed for racing and high-performance street applications. This 5.25" mount caliper combines stress-flow forged construction with advanced design features that maximize clamping efficiency while minimizing deflection.

Advanced Forged Construction:

• Stress-flow forged from premium billet aluminum—realigns metal grain structure within body contours for superior strength compared to standard machined billet
• FEA-optimized body design with fortified radial transitions between piston housings and bridges eliminates weak points and shoulders
• Radiused critical areas substantially increase resistance to deflection and body separation under extreme braking loads
• Includes center bridge bolt kit (standard on SI models) for additional reinforcement against body flex
• Fully detailed machined finish provides professional appearance for show or competition

Performance Features:

• Heavy-wall stainless steel pistons resist corrosion and reduce heat transfer from brake pads
• Thick piston wall construction prevents backside deflection for firm pedal feel even with power-boosted systems
• Quick-E-Clip pad retainers support 7812-type pads from top for fast service without caliper removal
• Slimmer profile design eliminates bottom pad supports for easier fitment in tight clearance applications
• Exclusive SRS bridge plates prevent pad gouging wear and eliminate pad rattle while dampening vibration harmonics that cause squeal
• Internal fluid passages with four-corner bleeder screws allow mounting in any front, rear, left, or right position
• Side inlet (SI) configuration for flexible plumbing options

The result is measurably reduced caliper deflection and fluid volume displacement, translating directly to shorter pedal travel, firmer pedal response, and more efficient clamping force—exactly what demanding racers and performance enthusiasts require.
