Wilwood Forged Dynalite Internal 4 Piston Brake Caliper - Type III Anodised Grey, 4.80 sq/in, 0.38 Inch (9.7mm)

The Wilwood Forged Dynalite Internal 4 Piston Brake Caliper is designed to deliver reliable, high-performance braking across a wide range of vehicle setups using 10 13 (254 330mm) diameter brake discs. It features an advanced spacer-less forged aluminium body with improved rigidity and reduced weight for consistent braking performance under load.Below are the key features that contribute to the caliper's performance, durability, and suitability for demanding use:Spacer-less Forged Aluminium Body: Manufactured without internal spacers using a single-piece forging process, this caliper offers improved strength and stiffness, resulting in less deflection under braking load and more consistent braking performance.Stress-Flow Forging Process: The forging technique re-aligns the metal grain flow to match the caliper shape, enhancing structural integrity and reducing internal weaknesses that would otherwise occur in block-milled bodies, which improves fatigue life and overall caliper durability.Radial Transition Bridge Design: Developed through finite element analysis, the rounded internal transitions between key caliper zones reduce stress risers and increase resistance to deformation, helping to maintain precise brake pad alignment under pressure.Compact Lightweight Design: With caliper weights starting from just 3.00 lbs (approx. 1.36 kg), the reduced unsprung mass improves suspension response and vehicle handling without compromising brake performance.Stainless Steel Pistons: These pistons resist corrosion and reduce heat transfer to brake fluid, helping to prevent fluid fade and maintain consistent pedal feel during repeated use.Flexible Mounting Compatibility: Designed to work with brake discs from 10 to 13 inches in diameter, giving you flexibility to use them across a range of car setups or adapt to different track requirements.Range of Surface Finishes: Available in anodised, powder-coated, or polished finishes to provide corrosion resistance and suit different aesthetic or environmental needs.If you're working on a road or track car where braking consistency, strength, and packaging are a priority, this caliper offers a strong balance of weight and performance. With features focused on strength and thermal stability, it's a smart addition to your braking setup for demanding use. The Forged Dynalite Internal caliper is a practical choice that gives you greater confidence in your braking system across varied conditions.SPECIFICATIONSuitable Rotor Size - 10"-13" (254-330mm)Number of Pistons - 4Piston Material - Stainless SteelPad Area - 6.36 in/sqMounting Type - RadialInlet Port - 1/8" NPTMounting Centre - 5.25" (133.4mm)Weight - 3.6lb (1.64kg)Calipers are non-handed and sold individually.Please note: Brake pads are not included but are available to purchase from our Motorsport brake pad category.
