STM-Spec D2/Swift Drag Racing Coilovers for Evo 7/8/9

The STM-Spec D2/Swift Coilover setup is now ready for your Evo 7/8/9. Engineered with drag racing in mind, we've meticulously tailored and tested this suspension to deliver a commanding launch, while also providing outstanding street manners with a firm, yet accommodating ride quality, making it versatile enough for mixed autocross applications. It's the complete package.

This is the exact same setup we employed in our 8.0 @ 182 STM Evo 8 RS build!

Your coilovers will be shipped with the springs pre-installed, though final adjustments will be necessary upon installation. If you have any questions regarding the setup process, feel free to contact us for assistance.

Vehicle Fitment:
2001-2006 Mitsubishi Lancer Evolution VII VIII IX

Setup Instructions:
1. Install coilovers at the desired ride height. No need to be perfect as it will change during the next few steps.
2. Once coilovers are installed and the car is back on the ground, jack the rear of the car up from the center (typically from the subframe is best).
3. While watching the suspension travel (spring compression), lower the car. As soon as the wheels are firm on the ground and the suspension starts to lower/travel, measure the distance of spring movement as you let the car the rest of the way down.
4. Using a Spring compressor, adjust the spring preload collar the same amount as the measured spring travel while letting the car down. (If the travel was 1", add 1" of preload to the spring collar) This will allow the shock to have maximum travel letting the suspension work through even the most aggressive launches.
5. Repeat these steps for the front.
6. Once the preload is determined and locked in, Adjust the ride height by spinning the body of the shock to the desired position/height.
7. You are now ready for an alignment.
