Do you already have lowering spring or are planning to get them and are confused about what shock absorbers to get? This can be confusing with so may choices out there. I recommend the KONI Sport Shocks.
1. KONI Sport Shocks are adjustable. You can adjust the damper for the amount of rebounding damping that you want. This allows you to change the handling characteristics of the car for your driving preference. Just about every aftermarket spring company uses a different spring rate. With the KONI adjustables you are able to set the dampers to work best with your aftermarket springs. Dampening of a shock/strut decreases with tens of thousands of miles and with the adjustability KONI offers you can continue to increase the dampening over time.
2. KONI's are designed to improve the handling of the car from the moment they are installed and I can personally attest that they do. I like the fact I can set them softer for the street and then if I am doing a track/autocross event I can firm them up for better handling.
3. KONIs are built for a lifetime. They have a limited lifetime warranty for the original purchaser. These will be the last shock/struts you will ever need to buy. My original shocks and struts for my car started to leak at around 38,000 miles. I now have over 109,000 miles and my KONIs are going strong. Here is a picture of my 04 Subaru Impreza WRX Wagon lowered on H & R Sport Springs with KONI Sport dampers.
