BC Racing has introduced the ASP Series (Adjustable Spring Perch) — a new suspension solution built for modern performance vehicles equipped with adaptive damping systems. Designed for drivers who want a lower stance and ride height adjustability, ASP kits allow you to fine-tune height while retaining full functionality of your factory electronic damping system.
As more vehicles rely on adaptive suspension technology, the ASP Series fills a critical gap between traditional lowering springs and full coilover conversions.

A smarter way to lower adaptive suspension vehicles
Lowering springs have long been a popular way to improve stance, but they come with limitations: fixed ride height, reduced flexibility, and less control over final ride height. Coilovers offer full adjustability, but on many modern vehicles they require disabling or bypassing electronic damping systems.
The BC Racing ASP Series offers a smarter alternative.
By combining vehicle-specific springs with adjustable spring perches, ASP kits allow precise ride height tuning while preserving the functionality of factory adaptive dampers. This means no warning lights, no loss of Comfort or Sport modes, and no compromise in the technology you paid for.
What is the ASP Series?
ASP stands for Adjustable Spring Perch — a height-adjustable spring system that replaces factory springs while working within the engineered travel range of OEM dampers. Each kit uses custom-tuned springs designed specifically for lowered ride heights and optimized damper performance.
This design allows drivers to achieve a tailored stance and improved chassis balance while maintaining the refined ride quality expected from modern adaptive suspension systems.
Why retaining electronic damping matters
Today’s performance vehicles — including BMW models with Adaptive M Suspension, Audi platforms with magnetic ride, and many late-model Japanese performance cars — rely on electronically controlled dampers to adjust ride quality in real time.
Traditional suspension upgrades often force owners to disable these systems, resulting in warning lights, reduced functionality, or a loss of selectable drive modes.
The ASP Series is engineered to avoid that compromise.
Because the system works with the factory dampers rather than replacing them, drivers retain full use of adaptive suspension modes while benefiting from a lower center of gravity and improved high-speed stability.
Key benefits of BC Racing ASP kits
- Ride height adjustability without full coilover conversion
- Retains OEM electronic damping and drive modes
- Vehicle-specific springs engineered for proper damper travel
- OEM-like ride quality with improved stability
- Ideal for modern adaptive suspension platforms
ASP vs lowering springs vs coilovers
The ASP Series occupies a unique position in the suspension market:
Lowering Springs
- Fixed ride height
- Limited adjustability
- Retains electronic damping
Coilovers
- Full adjustability
- May require disabling electronic damping
- More complex installation
BC Racing ASP Series
- Adjustable ride height
- Retains OEM electronic damping
- Balanced performance, comfort, and customization
Built for modern performance platforms
As vehicles continue to integrate advanced suspension technologies, upgrades must evolve alongside them. The BC Racing ASP Series reflects this shift, offering a solution that enhances stance and handling while preserving the functionality of electronic damping systems.
For enthusiasts who want the perfect ride height and full use of their adaptive suspension, the ASP Series delivers a modern, practical upgrade.
