Description

Improved shock dampening Multiple spring rate combinations Adjustable ride height: 1" to 3" OEM top hat compatibility Description Vehicle Fitment Technical Data Install Guide Progress Technology Series II Competition Coilovers for 92-00 Honda Civic (EG/EK) / 94-01 Acura Integra (DC2) EG and EK Civics and DC2 Integras have great suspension designs to begin with. They use double wishbones at all four corners, which is rare for cars this size. But after 25-plus years, most are on tired shocks, saggy springs, or a mismatched set of parts the last owner installed. The geometry is still good. The springs and shocks around it are worn out. Lower one on cheap springs and it bounces over every dip. Leave it stock and it floats and leans. Either way, the car doesn't handle the way it should. Progress's Series II Competition coilovers fix that with improved damping, 1 to 3 inches of adjustable ride height front and rear, and nine spring rate combinations to pick from. That's the real advantage here. Instead of one rate that's a compromise for everybody, you pick the rate that matches your car, your roads, and how hard you drive it. Get the rate right and these work as well for a daily driver as for a weekend autocross car. Get it wrong and you'll be unhappy either way, so read the guide below before you order. Picking Your Rate (Front/Rear) For daily drivers and street cars: 350/250: the most comfortable option. Good for a car that sees rough roads every day. 450/350: firmer up front, so the car leans a little toward understeer and feels safe and predictable. A good street-performance choice, especially with a heavier engine. 350/350: balanced, with less understeer than stock. Fun without getting harsh. For spirited driving and autocross: 350/450 and 350/550: stiffer in the rear, so the car turns in quickly and rotates instead of pushing wide. You'll feel more of the road. 450/450 and 450/550: more grip and very little understeer. A good match for swapped cars that still see…
