The Flatout SR coilover system offers a compelling blend of comfort and performance for the Audi A4 B8 S4 Avant Quattro, making it a popular choice for daily drivers who enjoy spirited driving and occasional autocross events. This review delves into the features, specifications, and benefits of this suspension upgrade.
Flatout SR Coilovers: Designed for the Enthusiast
The Flatout SR coilovers are engineered to provide a noticeable improvement in handling and responsiveness without sacrificing ride comfort. This balance is achieved through a combination of high-quality components and meticulous design. The system allows for a significant lowering range, from a subtle 0.5″ to a more aggressive 3.0″ both front and rear, enabling drivers to fine-tune their vehicle’s stance and center of gravity.
Key Features and Specifications
- Mono-Tube Shock Design: Facilitates easier rebuilds and potential future upgrades due to its modular construction. Individual components can be replaced or upgraded as needed.
- High-Quality Materials: Chromoly piston rod, proprietary aluminum piston, stainless steel shims, and medium-weight synthetic shock oil ensure durability and consistent performance. A nickel-plated shock casing provides excellent corrosion resistance.
- Optimized Spring Rates: Carefully selected linear coil springs or barrel springs (for short-stroke suspensions) provide the ideal balance between performance and comfort, maximizing adjustability and preventing spring binding. Specific spring designs cater to unique vehicle requirements, such as those found in certain BMW and European models.
- Adjustable Rebound: 20-point rebound adjustability allows drivers to fine-tune the damping characteristics to suit their driving style and road conditions.
- Camber/Pillowball Upper Mounts: Standard inclusion of camber plates and pillowball upper mounts (for a-arm suspensions) provides enhanced adjustability for precise alignment and handling. Multi-link rear suspensions typically utilize the OEM upper shock mount.
- Comprehensive Kit: Includes all necessary hardware, including 5mm wheel spacers to prevent rubbing issues, and may include adjustable end-links for the sway bar depending on the application. Rear knob extensions are also available upon request.
- 3-Year Warranty: Flatout offers a 3-year warranty against defects, providing peace of mind for buyers. Coilovers are hand-assembled and typically ship within approximately two weeks.
