The STM-Spec D2/Swift Coilover setup is now ready for your 15+WRX and 08+STi! Engineered with drag racing in mind, we've meticulously tailored this suspension to deliver a powerful launch while maintaining exceptional street manners and a firm yet forgiving ride quality. It's the ultimate all-in-one solution. This is the very setup we utilized in our 8.0 @ 182 STM Evo 8 RS build!
Your coilovers will be shipped with the springs pre-installed, although final adjustments will be required upon installation. If you have any inquiries about the setup process, feel free to reach out to us for assistance.
Vehicle Fitment:
2015-2021 Subaru WRX
2008-2021 Subaru STi
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.
