Riaction Coilovers

GT-1 : LINEAR

Our GT-1 Linear kit is the most Popular coilover system that we offer. This Coilover system offers a height adjustable body with 32 Levels of adjustable rebound for quick changes in ride quality and driving characteristics.

The linear valved kit is great for street driving, canyon carving and the occasional track-day.

GT-2 : Linear 2-way

The GT-2 Linear 2-Way kit is valved similar to the standard GT-1 kit with the same height adjustable body and rebound control, with the addition of compression adjustability on the external reservoir. The external reservoir also increases fluid capacity which helps lower fluid temperatures.

The linear 2-Way kit is perfect for those that take track driving more seriously and want more control out of the coilover system. Although the 2-Way kit is also great for street driving as well.

GP-1 : Digressive

The GP-1 Digressive Coilover has much more low speed control in comparison to a Linear valve. The resistance rate on the digressive valve increases as shaft speeds increase, but only to a pre-determined level. The digressive valving then has resistance that tapers off and as the shaft speed continues to increase, the resistance remains constant. This setup will do a better job of managing unwanted body motions while also still providing a comfortable ride.

The digressive coilover system is great for street use, canyon carving, and track days.

GP-2 : Digressive 2-Way

The GP-2 Digressive 2-Way kit is valved similar to the GP-1 digressive kit, with the same height adjustable body and adjustable rebound control, with the addition of compression adjustability on the external reservoir. Much like the Linear 2-way kit, the external reservoir increases fluid capacity and helps lower fluid temperatures.

The digressive 2-way kit will give much more confidence in driver feedback as well as a very stable vehicle from a more controlled weight distributing environment. Perfect for those looking for ultimate control and adjustability on the street, canyons, or track.
