Seat EZIII Sprint 15.5in 3pc Black Cover

The Seat EZIII Sprint 15.5in 3pc Black Cover by BUTLERBUILT is purpose-built for drivers and mechanics who demand professional-grade seating solutions in high-performance vehicles and race cars. Whether you're outfitting a dedicated track machine, a weekend warrior, or upgrading your daily driver with serious ergonomic performance, this three-piece modular seat cover system provides the structural support and durability that separated amateur builds from championship-level installations. BUTLERBUILT has earned respect in the automotive community for delivering race-proven seating that holds up under sustained lateral loading and extended driving sessions.

The EZIII Sprint design features a 15.5-inch width specification, engineered to fit intermediate frame widths without the bulk of heavier touring seats or the sacrifice of lateral support that narrower designs impose. The three-piece construction allows independent adjustment and replacement of individual components—cushion, back, and side bolsters—so damage to one section doesn't force a complete replacement. Black powder-coated or ballistic-grade covering resists UV degradation, abrasion from harness webbing, and the sweat and heat cycling that degrades lesser materials over time. At 25.4 lbs, this seat strikes a meaningful weight balance for vehicles where every pound matters, yet maintains the substantial padding and reinforced framework necessary for consistent support during cornering and braking events.

Mechanics and fabricators favor BUTLERBUILT seats when building or restoring road-course and autocross platforms, club racers, and street machines where OEM seating either lacks lateral hold or presents ergonomic misalignment with performance driving posture. Installation typically requires standard seat-mount hardware (cross-member mounting to existing frames or custom brackets) and works well paired with four-point or six-point harness systems. The modular design fits most contemporary race-car architectures and adapts readily to custom fabrication scenarios where standard seats prove incompatible with tube frames or fixed-seat enclosures. Verify mounting footprint and width clearance against your specific vehicle's interior geometry before ordering.
