The ALLSTAR PERFORMANCE C/O Slotted Top QA1/Carrera coil-over spring seat is a precision aluminum component engineered for high-performance suspension tuning on QA1 and Carrera shock absorber systems. This 2.5-inch inner diameter spring seat accommodates standard coil-over springs and features a drilled, black anodized aluminum construction that combines lightweight rigidity with corrosion resistance—critical properties for vehicles subjected to track duty, road racing, or sustained performance driving where suspension geometry and spring preload adjustment directly impact handling dynamics.
The slotted design enables fine-tuned spring preload adjustments without requiring complete shock disassembly, a feature that streamlines setup time during testing or mid-event suspension changes. The 2.5-inch ID specification is the industry standard for most modern coil-over spring kits, ensuring compatibility across a wide range of aftermarket suspension systems. Black anodizing provides both aesthetic consistency with shock bodies and a durable protective layer against salt spray, moisture, and thermal cycling—considerations that matter significantly during extended track sessions or off-season storage. Aluminum construction keeps unsprung mass minimal, reducing rotational inertia at the wheel.
This component is designed for suspension builders, performance shops, and serious amateur racers working with QA1 or Carrera shock platforms. Whether assembling a custom coil-over package for a road course car, drift platform, or bracket racing vehicle, this seat provides the structural interface between the spring and shock body. Individual unit sale allows replacement or upgrade of a single seat without purchasing a complete shock assembly, making it an economical choice for maintenance or system reconfiguration.
Compatible with QA1 and Carrera coil-over shock systems that use 2.5-inch spring bores, this seat represents a core suspension component for any builder prioritizing adjustability and lightweight design. Sold individually.
