IAG Spec Street Series Coilovers by Fortune Auto for 2015-21 WRX/STI

IAG Performance and Fortune Auto have joined forces to bring you the IAG Spec Street Series Coilovers By Fortune Auto, designed for the 2015-2021 Subaru WRX and STI vehicle models. These single adjustable coilovers strike the perfect balance between everyday driveability and occasional track use, enhancing the handling of your vehicle without compromising comfort. This complete kit, featuring both front and rear coilovers, delivers improved handling and performance at an unbeatable price.

At IAG Performance, we're committed to pushing the boundaries of automotive performance. Through constant research, development, and testing on countless track days, we’ve developed a reputation for innovation. When we find a part we like from a brand we trust, like the Fortune Auto 500 Coilovers, we take it a step further to make it even better. The IAG Spec Street Series Coilovers are the result of our commitment to perfection. We've enhanced key features of the Fortune Auto 500 Coilovers, improving performance, road feel and overall handling to deliver a coilover system that’s optimized for both street and track use.

The enhancements in the IAG Spec Street Series Coilovers focus on refining suspension travel and improving everyday driving comfort, while still delivering track-worthy results. With an extra 10mm of front shock stroke compared to Fortune Auto’s coilovers, we’ve optimized suspension travel, resulting in a more forgiving and smooth ride. The softer 7kg/mm front spring allows for optimal weight transfer to the front during braking and to the rear during acceleration. Our 8-inch front spring increases travel, reducing the risk of bottoming out, while the extra 10mm stroke restores the suspension travel that’s often reduced when lowering your coilovers. When you're finished attacking the tarmac, the 24 clicks of rebound and compression adjustment allow you to convert your suspension from track-focused to comfort without compromise.

The IAG Spec Street Series Coilovers By Fortune Auto are equipped with a 1 inch extended top hat, which allows the shock absorbers to travel within their optimal range, even if the vehicle has been lowered. This adjustable coilover kit makes it easy to drop your car to gain the benefits of improved handling, aerodynamics, improved traction and road feel. Incorporating an extended top hat allows the full range of shock stroke, maintains the correct preload, all while avoiding damage to your coilovers.

The IAG Spec Street Series Coilovers By Fortune Auto incorporate the use of lightweight and durable T6061 aluminum in the camber plates and spring perches to maximize weight savings without compromising the strength or integrity of the suspension. Additionally, the coilover springs are constructed from an advanced premium alloy of chrome silicone, providing both elasticity and strength, ideal for high-performance applications.

The IAG Spec Street Series Coilovers feature Fortune Auto’s Flow Digressive piston technology, which allows for stiff low-speed compression and rebound movement. To compensate for fast stroke speeds like high speed bumps or rough roads, the coilovers automatically adapt to become supple, providing superior mechanical grip and control, even over irregular surfaces. This technology delivers the best of both worlds, offering a versatile shock absorber that excels in everyday driving, as well as occasional track use.

It’s been a privilege to team up with Fortune Auto to create the IAG Spec Street Series Coilovers. Known for their cutting-edge suspension solutions and race-winning innovations, Fortune Auto’s relentless pursuit of performance and quality has resulted in systems that offer exceptional handling, comfort, and durability at an affordable price.
