BC Racing ASP Series Adjustable Spring Perch Kits
BC Racing Adjustable Spring Perch (ASP) kits are the ideal suspension upgrade for drivers who want a lower, more aggressive stance while retaining full functionality of their factory electronic damping and adaptive suspension systems. Designed for modern performance vehicles, ASP kits provide height adjustability without the compromises often associated with traditional lowering springs or full coilover conversions.
As adaptive suspension becomes standard on more platforms, enthusiasts need solutions that enhance stance and handling without disabling the technology they paid for. The BC Racing ASP Series delivers exactly that — height adjustable springs engineered to work seamlessly with OEM dampers, preserving ride modes, comfort, and everyday drivability.
What is the BC Racing ASP Series?
ASP stands for Adjustable Spring Perch. Each kit combines vehicle-specific performance springs with an adjustable perch system that allows precise ride height tuning. Unlike fixed lowering springs, ASP kits give you the flexibility to dial in your stance while maintaining proper suspension travel and predictable handling.
Because the springs are engineered around OEM damper characteristics, the result is a refined driving experience with improved stability and control — even at lowered ride heights.
Why choose height adjustable springs?
Traditional lowering springs lock you into a predetermined drop, which may not suit your wheel setup, road conditions, or performance goals. Coilovers offer full adjustability but often require deleting or bypassing electronic damping systems. The BC Racing ASP Series bridges this gap by providing adjustable ride height while preserving adaptive suspension functionality.
This makes ASP kits an excellent choice for drivers who want customization without sacrificing comfort, technology, or reliability.

Built for modern adaptive suspension vehicles
As more vehicles adopt electronically controlled dampers, suspension upgrades must evolve. The BC Racing ASP Series is designed with these platforms in mind, allowing you to lower your vehicle and fine-tune ride height while keeping the factory damping system working as intended.
Whether you’re aiming for a subtle drop or a more aggressive stance, ASP kits provide the flexibility to customize your suspension without compromising comfort or the advanced features of your OEM adaptive system.
