Progress Coilover II System 88-91 Honda Civic / CRX (350/350) Description
The new Progress Coilover Systems for the 1988-1991 Honda Civic / CRX have been redesigned with improved shock dampening rates, modern foam-type bump stops, and less part content for a simple and durable sport suspension system. This is a perfect system for street performance, new track day and autocross entusiasts, as well as project cars with engine swaps.
THREE Competition Series II (CS-II) CALIBRATIONS ARE AVAILALE. They are explained below:
STREET PERFORMANCE - ORDER part # 77.0101
These kits use 350# front and 250# rear springs. This calibration rides well on uneven road conditions if set up at a reasonable ride height around 1.0" to 1.5" less than OEM. Expect a dramatic improvement in handling capability and steering response. This is the choice for sport-tuned "daily drivers".
STREET-SPORT - ORDER part # 77.0101.SS
These kits use 350# front and 350# rear springs. This calibration is more aggressive and transitions faster for the "sport" driver. Expect a dramatic improvement in handling capability and response, and some reduced ride quality. This is the great choice for "street and track day" multi-use vehicles, and vehicles driven hard on better (smoother) roads.
AUTOCROSS /DRAG LAUNCH - ORDER part # 77.0100
These kits use 350# front and 500# rear springs. This calibration has more grip, and is intended for use with "performance" alignment settings and sticky tires. If ride quality is a major concern, don?t go here because the stiffer rear springs make for an uncomfortable (choppy) highway ride. This is a more balanced and less forgiving setup intended for enthusiast track days and autocross events. This kit will also launch well for mild drag applications. Expect a huge improvement in handling capability. This would also be a great low-budget setup for new (road racing) drivers going to a (track) driving school.
For the sake of comparison, typical OEM spring rates for these applications are approximately 220#/in front, and 110#/in rear. With the numerous Civic & Integra applications, there is a range of spring rates, and these CS-II systems are significant upgrades from your OEM damper and spring calibrations.
