The IAG Spec Street Series Coilovers By Fortune Auto are equipped with a 10mm extended travel front and rear, 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.

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. In addition, 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, along with occasional track use.
