Many of the earlier models feature an active electronic suspension setup. If you are not going with something like the TEIN system, but want to keep your factory adjustable suspension (the KYB GR-2s are NOT adjustable), then you will need the factory ECS struts. Get them here!! If you have a later year model, or non-turbo without the ECS adjustable suspension, you can also get the NON-ECS struts here as well.
Note: These are sold individually - add 2 to cart for a pair.
