The Street Performance Standard: EB4 Forged 4-Piston Caliper

Transform your daily driver’s braking performance with the EB4 caliper. This is the ideal first step into the world of big brakes, engineered to deliver a massive improvement in stopping power and pedal feel over your factory setup. Its lightweight, asymmetrical forged design ensures a perfect balance of strength and performance.

The EB4’s ultra-rigid, reinforced body eliminates caliper flex, giving you a firm, confident pedal that responds the instant you need it. We packed it with high-performance components, including ventilated pistons and high-temperature seals, to deliver consistent, fade-free braking even under aggressive street driving. It's the perfect, cost-effective upgrade for daily driven cars, crossovers, and compact SUVs.

Is this a worthwhile upgrade over my stock brakes?
