For more information, visit www.P65warnings.ca.gov.The APR Roll-Control Lowering Springs (SUS00021) are the premier suspension solution for the VW MK7 Jetta GLI, designed to bridge the gap between aggressive aesthetics and daily-driveable comfort. Unlike many "drop springs" that offer a harsh, bouncy ride, APR’s engineering team utilized extensive street and track testing to develop a specific ride height and spring rate configuration. This system significantly lowers the center of gravity and increases spring rates by over 50%, resulting in a car that feels more planted through corners with a dramatic reduction in body roll.
Constructed in the USA from premium high-tensile chrome silicon steel, these springs are finished in APR’s signature Red powder coating for superior corrosion resistance. They utilize a dual-rate design that transitions into a linear feel under load, ensuring the suspension remains predictable during spirited driving while staying supple enough for commuting. Whether your GLI is equipped with DCC (Dynamic Chassis Control) or standard dampers, these springs are a direct plug-and-play upgrade.
Key Features:
- Perfect Stance: Delivers a balanced drop of approximately 33mm (1.3") in the front and 38mm (1.5") in the rear.
- Enhanced Handling: Increases spring rates by 50% (Front) and 59% (Rear) to sharpen turn-in and stability.
- Dual-Rate Engineering: Provides a "linear" feel during loaded driving while maintaining comfort during normal cruising.
- DCC Compatible: Specifically tuned to work seamlessly with both factory DCC electronic dampers and standard Non-DCC dampers.
- Premium Materials: Made in the USA from chrome silicon steel to prevent sagging and ensure long-term durability.
- Anti-Bottoming Design: Optimized ride height prevents the dampers from constantly "crashing" over large bumps.
Technical Specifications:
| Metric | Front Specification | Rear Specification |
|---|---|---|
| Approximate Drop | 33 mm (1.3 in) | 38 mm (1.5 in) |
| Final Spring Rate | 323 lbs/in (+50% vs stock) | 362 lbs/in (+59% vs stock) |
| Spring Design | Dual-Rate (148 - 323 lbs/in) | Dual-Rate (218 - 362 lbs/in) |
| Material | High Tensile Chrome Silicon Steel | |
Performance Tip: For the ultimate balance of handling and ride quality, APR highly recommends combining these springs with the APR Performance Bumpstop Kit (SUS00025) to optimize damper travel.
