Eibach 2022+ Honda Civic Si Pro-Kit 彈簧組

Installed these over the weekend and the drop is exactly what the Si needed—sits about an inch lower with a much more aggressive stance. The lower center of gravity is noticeable in corners, and the ride is still comfortable for daily driving.

The progressive spring design really smooths out rough pavement while still reducing body roll in corners. Install was straightforward and the ride height looks perfect without being too aggressive.

The drop is subtle enough that the car still looks stock to anyone who doesn't know, but the lower center of gravity is immediately noticeable in corners. Progressive springs soak up bumps way better than I expected for this price.
