Prothane 8-2015 Total Suspension Bushing Kit Honda Civic Si 1999-2000 with Upper Bushings

The Prothane 8-2015 Total Kit is a comprehensive polyurethane suspension bushing kit engineered for the 1999–2000 Honda Civic Si with upper bushings included. Prothane's polyurethane bushings are a direct upgrade over worn or soft OEM rubber bushings, delivering tighter chassis response, reduced flex, and significantly longer service life under demanding street and performance driving conditions.

Polyurethane outperforms standard rubber by resisting compression set, oil, and heat degradation — common failure points in factory suspension components. This kit restores or improves suspension geometry and steering precision by eliminating the vagueness associated with deteriorated rubber bushings.

Key Features:

• Complete total kit — includes all major suspension bushings needed for a full refresh
• Includes upper bushings for comprehensive front suspension coverage
• Made from high-durometer polyurethane for enhanced durability and performance
• Direct replacement fitment — no modifications required for installation
• Resists oil, heat, and ozone degradation for extended service life
• Improves chassis feedback, handling precision, and suspension response
• Supplied with grease for proper installation and long-term performance

The Prothane 8-2015 is an ideal solution for Civic Si enthusiasts looking to eliminate suspension slop, restore factory geometry, or build a more responsive chassis for spirited driving or autocross use.
