* READ THE INSTRUCTIONS
* KW suspension is a German manufacturer and the instructions come in German and English.
* A clean work area and basic safety equipment such as safety goggles and gloves are recommended.
* Extra care is required when working with struts and compressed springs. Wear gloves. Be safe.
1. While individual wheels can be done with a jack and jackstands, using a lift is considerably more convenient for easy access.
2. A spring compression tool is essential. They can be rented at most local auto parts stores. The rest can be accomplished
with normal hand tools.
3. Adjusting the rear ride height is more difficult than the front and it becomes more convenient to drop the whole assembly down
to make the adjustment process easier.
4. We also used short bits of two by four wood blocks to gain additional compression of the springs during installation.
5. The kit requires elimination of the factory sport suspension ride adjuster, but the difference is not discernable and the car
drives and handles beautifully even though we raised the front ride height 1-inch and the rear 1/2- inch.
6 Front adjustments are easily accomplished, but the rear requires that you drop the assembly back down to gain access with
the spanner wrench.
7 Best performance and longevity will be derived from your new Goodyear tires if you obtain a high quality balance job and
ensure that the front end is properly aligned to factory specs. Also pay close attention to fluctuations in tire pressure in seasonal
weather and always run the manufacturer's recommended tire pressure.
