THE IAG SPEC DIFFERENCE: WHERE INNOVATION MEETS UNBEATABLE PERFORMANCE – 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.
COILOVER SPECS – The front suspension in the IAG Spec Street Series Coilovers By Fortune Auto are engineered to the following specifications. Front: 117mm front shock stroke, custom shock valving, 240mm shock body, 7-inch spring length, 5kg/mm spring rate. The rear suspension coilovers meet the following specifications: 100mm rear shock stroke, custom shock valving, 200mm shock body, 7-inch spring length, 6kg/mm spring rate. Our Street Series Coilovers are equipped with 1” extended top hats.
CUSTOM TUNED – NOT OFF THE SHELF – With an extra 9mm 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 5kg/mm front spring allows for optimal weight transfer to the front during braking and to the rear during acceleration. Our 7-inch front spring increases travel, reducing the risk of bottoming out, while the extra 9mm 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.
EXTENDED REAR TOP HAT – 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. The adjustability of this 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 potential damage to your coilovers.
LIGHTWEIGHT AND DURABLE CONSTRUCTION – The IAG Spec Street Series Coilovers By Fortune Auto incorporate the use of lightweight, yet 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.
FLOW DIGRESSIVE TECHNOLOGY BY FORTUNE AUTO – 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 and occasional track use.
