Product Details
Our Lowering Springs transform your factory dampers into a fully height-adjustable coilover suspension system without sacrificing EDC (Electronic Damping Control). By pairing chassis-specific sporty spring rates with custom sleeve-over hardware, this kit improves handling dynamics, reduces body roll, and lets you precisely control vehicle stance and chassis balance.
Unlike fixed lowering springs, this system features threaded perches that enable exact ride-height adjustments, adjustable up to -1.5" in the front and -0.875" in the rear. This adjustability allows drivers to dial in aesthetics, eliminate uneven fender gaps, or corner-balance the vehicle for optimized cross-weight distribution at the track. The upgraded spring rates work in tandem with the original valving of the OEM dampers, retaining full utility of the factory and drive modes.
Complete with a laser-etched Allen key size reference to prevent hardware damage during setup. High-density polyethylene (HDPE) spring isolators are integrated to prevent metal-on-metal contact, eliminating binding. The system also features dedicated mounting points for the stock accelerometer sensors, ensuring seamless sensor integration
FEATURES
- Threaded sleeve-over perches allow precise corner balancing and ride height tuning
- Range of adjustability: -0.375" to -1.5" (front), 0" to -0.875" (rear).
- Integrated accelerometer mounting brackets retain full factory Electronic Damping Control (EDC) sensor feedback and cabin mode selection.
- High-rate performance springs tune overall roll stiffness while remaining within range of the OEM shock valving.
- CNC-machined 6061-T6 billet aluminum construction for all threaded adjustment sleeves and spring perches.
- Pinch-bolt locking mechanism with laser-etched Allen socket dimensions prevents thread galling during adjustments.
- High-density polyethylene (HDPE) lower perches isolate the spring coils to prevent metal-on-metal binding, coil clash, and noise transmission.
